Abstract	Abstract. Agus A, Agussalim, Sahlan M, Sabir A. 2021. Honey sugars profile of stingless bee Tetragonula laeviceps (Hymenoptera: Meliponinae). Biodiversitas 22: 5205-5210. Honey was a functional food to improve human health, but irresponsible people used this circumstance to make fake honey. This study aimed to evaluate the profile of the sugar of stingless bee honey [Tetragonula laeviceps (Smith, 1857)] from different geographical origins in Indonesia. Honey, three samples were directly collected from three other sources for meliponiculture of T. laeviceps in Indonesia: Sleman, Klaten, and Gunungkidul. The honey sugars profile was analyzed: glucose, fructose, sucrose, reducing sugar, the sum of fructose and glucose, glucose to moisture ratio, fructose to glucose ratio, and honey pH. Glucose and fructose were analyzed by HPLC, sucrose by Luff Schoorl, reducing the sugar by Layne-Enyon, and pH by a pH meter. The current findings revealed that the geographical origins had a highly significant effect on glucose, fructose, the sum of fructose and glucose, glucose to moisture ratio, fructose to glucose ratio, and honey pH (P<0.01) and significant effect on reducing sugar (P<0.05), but not on sucrose content. Thus, it can be concluded that the origins were affecting the honey sugars profile and honey from Sleman has the highest sugars content, followed by honey from Klaten and the lower was honey from Gunungkidul.

Abstract	Vaginal candidiasis characterized by abnormal vaginal discharge and itching usually treated by azole’s drug or nystatin; however, some results of treatment are unsatisfied and become recurrent. Propolis containing polyphenols and flavonoids is known to have anti-inflammatory and antimicrobial activity. This study investigated the effect of Indonesian propolis wax from Tetragonula sp. as a therapy in limited vaginal candidiasis patients. The subjects were women who came to the Tasik Community Health Centre met the inclusion criteria such as clinical complaint and laboratory evaluation (positive hyphae/pseudohyphae and culture on Sabouraud Dextrose Agar (SDA) medium) from a vaginal swab. Evaluation of anti-candida effect of propolis was determined by clinical remission and the absence of Candida’s growth on SDA medium. Forty subjects were randomly assigned to those receiving treatment by ovule propolis (n = 20) and that treatment by nystatin (n = 20) as a control, once daily, for seven days, respectively. All methods have been approved by the Ethics Commission of the Faculty of Medicine, Universitas Indonesia. Our results indicated no significant difference in the laboratory evaluation of patients who have treated ovule propolis compared to standard therapy. This study suggests that propolis wax has a beneficial effect to develop as an anti-candida agent for vaginal candidiasis therapy.

Abstract	Propolis is widely used as traditional medicine since ancient times. It was necessary to conduct the pre-clinical study because of its relevant curative properties. This study aimed to investigate in-vitro antioxidant, standardize quality parameters, study acute toxicity, and determine in-vivo anti-inflammatory. Three spectrophotometric methods were used to determine antioxidant activity. The standardization includes physical, chemical, and microbiological evaluation. Furthermore, an acute toxicity test was conducted using 20 female Sprague Dawley (SD) strain rats divided into 4 groups with different dose of propolis. The in vivo anti-inflammatory test was carried out using the carrageenan induction method on rats' soles. A total of 36 female SD rats were classified into 6 groups as follows, Group normal, negative control, diclofenac sodium, and three propolis groups (72; 144; and 288 mg/kg BW). The results demonstrated the IC50 values of the DPPH and ABTS scavenging activity 9.694 ppm and 2.213 ppm, respectively. The FRAP reducing power was 189.05 mg AaE/g. The physical appearance of propolis capsule was vegicaps as white – white, size 0, with light brown granule. Moreover, the content weight was 418.88 mg with a disintegration time of 7 min 53 s, while the water, flavonoid, and polyphenol contents were 9.07%, 1.59%, and 98.0821 mg GAE/g respectively. The content of heavy metal and microbial contamination were not detected. The acute toxicity results showed LD50 ≥ 5 g/kg BW, no toxicity symptoms, and no abnormalities in all rats. The anti-inflammatory inhibition percentage for groups III, IV, V, and VI was 11.86%, 6.53%, 7.81%, and 6.63% respectively, while the anti-inflammatory drugs effectiveness percentage compared to positive controls were 55.00%, 65.83%, and 55.83% respectively. Based on these results, it can be concluded that propolis capsules fulfilled the standardization requirements, and it is likely to be non-toxic, and effective as antioxidant and anti-inflammatory.

Abstract	Molecular docking and dynamics simulations were conducted to investigate the antiviral activity of Propolis Sulabiroin-A to inhibit the SARS-CoV-2 virus with quercetin, hesperidin, and remdesivir as control ligands. The parameters calculated were docking score and binding energy/molecular mechanics-generalized born surface area (MMGBSA), root mean square displacement (RMSD), and root mean square fluctuation (RMSF). Docking and MMGBSA scores showed that all the ligands demonstrate an excellent candidate as an inhibitor, and the order of both scores is hesperidin, remdesivir, quercetin, and sulabiroin-A. The molecular dynamics simulation showed that all the ligands are good candidates as inhibitors. Although the fluctuation of Sulabiroin-A is relatively high, it has less protein–ligand interaction time than other ligands. Overall, there is still a good possibility that sulabiroin-A can be used as an alternative inhibitor if a new structure of receptor SARS-CoV-2 is used.

Abstract	Dental caries is a disease caused by the microbial infection that produces localized damage to the tissue classification. The process begins by demineralization in hard tissue followed by damage to the organic material. Dental caries happens because of demineralization without balanced by remineralization. In this study, tooth powder spray and tooth liquid spray was made with active ingredients of 10% w/w CPP-ACP (Casein Phosphopeptide - Amorphous Calcium Phosphate) and EEP (Ethanolic Extract Propolis), with the variation of 0%, 2%, and 4% w/w EEP in each preparation to inhibit demineralization. Each preparation should pass organoleptic and viscosity study to maintain the quality. pH of each preparation was evaluated to ensure that each preparation has pH above the critical pH of the oral environment. The stability of polyphenol as the antibacterial agent was evaluated for a month to assure the bioavailability in the preparations. The result shows that each preparation has enough organoleptic aspect and proper viscosity. pH level in each preparation is stable above critical pH of mouth environment (5.5), it ranges between 6.5 – 7.12. Polyphenol content in each preparation is stable with highest polyphenol content in tooth powder spray of 4% EEP, i.e. 1.39 – 1.45% (w/w). Qualitative evaluation of tooth morphology by SEM shows that preparations can inhibit enamel demineralization relatively to negative control.

Abstract	We revealed the plant origin of propolis from Lombok, Indonesia; its plant origin was Calophyllum inophyllum Linn. This was confirmed by observing the behavior of stingless bees and from the LC-MS analysis of the 70% ethanol extracts of the propolis and C. inophyllum resin. Furthermore, a new chromanone derivative, calophylloidic acid A (1), was isolated from the stem bark resin of C. inophyllum. The structure of 1 was elucidated using a combination method based on the IR, UV, HRESIMS, and 1D and 2D NMR analyses. The absolute structure of C-2 and C-3 positions of 1 was determined by electronic circular dichroism (ECD). This determination was supported by the time-dependent density functional theory (TD-DFT) and ECD calculations. Additionally, the C. inophyllum resin, propolis, and 1 exhibited significant antibacterial activity against Staphylococcus aureus and Escherichia coli.

Abstract	Diabetes mellitus (DM) is a metabolic disease characterised by chronic hyperglycaemia with impaired carbohydrate, fat and protein metabolism caused by defects in insulin secretion or action. Based on our previous research, stingless bee honey (SLBH) from Tetragonula biroi and T. laeviceps can inhibit alpha-glucosidase activities. Therefore, the aim of the present study was to determine the effects of daily oral administration of SLBH on body weight (BW) and fasting blood glucose (FBG) levels of male rats with streptozotocin (STZ)-induced DM. Thirty-six male Sprague Dawley rats were divided into six groups of six rats each. One group of normal non-diabetic rats served as a positive control. The diabetic groups were intraperitoneally (i.p.) injected with STZ (50 mg/kg BW) for induction of DM and divided into five equal subgroups of six animals each: an untreated group as a negative control; a group treated with 0.6 mg/kg BW of glibenclamide as a positive control and three SLBN treatment groups that had daily oral administration of 0.5, 1.0 or 2.0 g/kg BW, respectively, for 35 days. The results showed that SLBH significantly reduced loss of BW in diabetic rats. FBG levels in diabetic rat blood, collected from the tail, were measured using Accu-Chek test strips. The FBG levels in diabetic rats that have oral administered intake with glibenclamide and SLBH were stable. There were no changes in serum FBG levels in SLBH-treated diabetic rats for 35 days. Pancreatic histopathology results from all groups showed no abnormalities or tissue damage in either diabetic or non-diabetic rats. The results of this study show that administration of SLBH reduced BW loss or improved BW of rats with STZ-induced DM. Meanwhile, the reduction in loss of BW that occurred in diabetic rats after 35 days of SLBH administration was the result of reduced formation of fats and proteins, which are broken down into energy. Further research is needed to determine the antidiabetic effects of honey from other stingless honeybee species.

Abstract	Three new compounds, namely sulabiroins A (1) and B (2), and 2',3'-dihydro-3'-hydroxypapuanic acid (3), were isolated from the propolis of stingless bees (Tetragonula aff. biroi) collected on South Sulawesi, Indonesia. In addition, ten known compounds, (–)-papuanic acid (4), (–)-isocalolongic acid (5), isopapuanic acid (6), isocalopolyanic acid (7), glyasperin A (8), broussoflavonol F (9), (2S)-5,7-dihydroxy-4'-methoxy-8-prenylflavanone (10), isorhamnetin (11), (1'S)-2-trans,4-trans-abscisic acid (12), and (1'S)-2-cis,4-trans-abscisic acid (13) were identified. The structures of the new and known compounds were determined by spectroscopic analysis. The absolute configurations of sulabiroins A (1) and B (2) were determined by X-ray crystallography analysis and ECD calculation, respectively. The propolis from stingless bee (Tetragonula aff. biroi) collected on South Sulawesi contained compounds not present in propolis from other regions. Sulabiroin A (1) and isorhamnetin (11) were examined for xanthine oxidase (XO) inhibitory activity as one of biological activities; isorhamnetin (11) exhibited potent XO inhibitory activity, with an IC50 value of 3.9 µm.

Abstract	Propolis is a mixture of resin and saliva of Tetragonula spp. that have antifungal activity. The purpose of this study was to develop spray-dried microcapsule propolis (SDMP) and to analyze its antifungal activity to Candida albicans. The SDMP was obtained using a spray drying method by maltodextrin and gum arabic coating. The antifungal activity of SDMP of rough propolis (taken from the outside beehive) and smooth propolis (taken from the inside beehive) was analyzed. The macroscopic characterization showed that SDMP has a powder form with brownish-yellow color. The microscopic characterization showed SDMP has a spherical uniform particle shape with particle size 9.32 - 14.61 µm. The encapsulation efficiency of smooth and rough SDMP was 81.22% and 83.04%; moisture content 5.58% and 5.84%; water solubility 98.19% and 98.31%, respectively. The microbial inhibitory concentration to C. albicans was the diameter of 6.33±1.5 to 10±2.5 mm. SDMP displayed remarkable activity in the assays against C. albicans.

Abstract	The stingless bee, Tetragonula sapiens, is one of the species producing propolis in Indonesia. To date, there is still limited information about the standard characteristics and biological activity of propolis. This study investigated the standardized extract of Indonesian propolis in terms of its potency for controlling diabetes and high blood pressure in vitro, in accordance with its standard parameters. Three types of extracts; i.e., ethanolic extract of propolis (EEP), spray-dry propolis without wax (SDPNW), and spray-dry propolis with wax (SDPW); were prepared from T. sapiens stingless bees collected in South Sulawesi, Indonesia. The ethanolic extractable, loss on drying, ash, and water content parameters of EEP, SDPNW, and SDPW met the natural extract requirement. There is no significant value for their residual solvent levels (<0.54%), heavy metals (the absence of As, Cd, Pb, and Hg contamination), or the absence of microbial contamination. ACE inhibition activity on captopril, EEP, SDPNW, and SDPW had IC50 values of 5.97, 115.06, 112.93, and 116.70 ppm, respectively. While the IC50 values of acarbose, SDPNW, EEP, and SDPW for antidiabetic activity of α-glucosidase inhibition were 53.34, 56.48, 60.09, and 68.28 ppm, respectively. The TFC and TPC content of SDPNW were higher than EEP and SDPW, with values of 1.59% and 1.93%, respectively. It can be said that Indonesian propolis extract meets the standards for an extract and has the potential to reduce diabetic and hypertensive diseases. Further preclinical and clinical studies are needed to develop standardized propolis extract as an anti-diabetic and antihypertensive agent.
