    Abstract The study entailed the investigation of the roots of Euphorbia wallichii, which resulted in the isolation of 29 ent-atisane diterpenoids (1-29), 14 of which were previously unknown. These previously undescribed ones were named euphorwanoids A-N (3-5, 7, 9, and 10-18). Various techniques, including comprehensive spectroscopic methods and calculated electronic circular dichroism, were employed to determine their molecular structures. Additionally, the absolute configurations of ten ent-atisane diterpenoids (1, 2, 5, 6, 8, 9, 11, 12, 14 and 16) were established through X-ray crystallographic analyses. All isolated compounds' potential to inhibit the influenza A virus in vitro were evaluated. Compounds 18, 20, and 24 exhibited notable antiviral activity against the A/Puerto Rico/8/1934 strain. Their effective concentrations for reducing viral activity (EC

    Abstract A chemical study focusing on the N-containing constituents of Hymenocallis littoralis was carried out, leading to the isolation of two new alkaloidal flavonoids (1–2) and five known alkaloids (3-7). Structures of the isolated compounds were established mainly by spectroscopic techniques, including NMR spectroscopy and mass spectrometry as well as the CD experiment. These compounds were subjected to the in vitro cytotoxicity assays using Hep3B cells, and among them only the known pancratistatine (3) and lycorine (5) could significantly inhibit the Hep3B cell proliferation.

    Abstract Perennial herb Hymenocallis littoralis(Amaryllidaceae) boasts anti-tumor, anti-virus, and anti-inflammatory activities. As the representative constituents, alkaloids have attracted much attention, whereas the non-alkaloid constituents have been rarely reported. Therefore, this study investigated the non-alkaloid constituents of H. littoralis and their contribution to the various pharmacological activities of the herb. Thirteen non-alkaloid compounds were isolated from the 95% ethanol extract of dried whole plant of H. littoralis after a series of chromatographic separation steps and spectral analysis, and they were identified as 5,7-dihydroxy-6,8-dimethoxy-2-hydroxymethyl-4H-chromoen-4-one(1), undulatoside A(2),(2S)-7,4'-dihydroxyflavane(3), naringenin(4), 4',7-hydroxy-8-methylflavanone(5), 8-methylnaringenin(6), 8-demethylfarrerol(7), 6-methyl-aromadendrin(8), 4',5,7-trihydroxy-8-methylflavanone(9), syzalterin(10), 6-methylapigenin(11), isoliquiritigenin(12), and undatuside C(13) based on the spectroscopic data analysis. Among them, compound 1 was a new chromone derivative, and compounds 2 and 4-13 were isolated form this plant for the first time.

    Abstract A phytochemical study was carried out on the extract of Trillium tschonoskii rhizomes, resulting in the isolation of thirty-six steroidal glycosides (1-36). Their structures were established mainly by spectroscopic analyses as well as necessary chemical evidence, of which 1-25 were identified as new analogues. Herein, all the isolated analogues were screened for the cytotoxicity against intrahepatic cholangiocarcinoma (ICC) cell lines of HuCCT1 and RBE through tumor colony formation and CCK-8 survival analysis, and the results demonstrated that three compounds 9, 12, and 26 significantly repressed tumor colony and sphere formation in both cell lines, respectively. Furthermore, the three analogues possessed a remarkable inhibitory role of organoid formation established from hydrodynamic induced mouse primary intrahepatic cholangiocarcinoma. Moreover, the functional assays of flow cytometry analysis, cancer stemness related gene expression, and western blotting assays all indicated that compound 26 could significantly repress cancer stem markers. Taken together, these results demonstrate that steroidal glycosides derived from T. tschonoskii rhizomes could be potentially implicated in human ICC therapy.

    Abstract The change of icariin( ICA) content in thirty-three samples of five Epimedium species listed in the Chinese Pharmacopoeia( 2015 edition),including E. brevicornu,E. sagittatum,E. pubescens,E. koreanum,and E. wushanense has been investigated in this study. The results indicated that the optimized process procedure was baking at 150 ℃ for 30 min,and 3'''-carbonyl-2″-β-L-quinovosyl icariin( CQICA) could not be translated into ICA and ICA could be converted under this heating process condition. ICA increased remarkably after the heating process by 1-3 times in E. brevicornu,E. wushanense and E. koreanum,and increased lightly in E. brevicornum and E. pubescens,while ICA slightly increased or decreased in E. sagittatum and E. wushanense.

    Abstract The safety evaluation of timosaponin BII (TBII) in beagle dogs with toxicokinetic study was performed. For the acute oral toxicity study, the minimum lethal dose (MLD) of TBII was more than 2000 mg/kg and suggested the characteristics of absorption saturation. For the 28-day repeated dose oral toxicity and toxicokinetic studies, there was no significant effect on all test parameters except for prolonged APTT in the 60 and 180 mg/kg groups, which recovered after withdrawal. The increase of drug exposure of 180 mg/kg group was not proportional to the increase of administration dose, showing the characteristics of absorption saturation.

    Abstract Six new prenylated flavonoid glycosides, including four new furan-flavonoid glycosides wushepimedoside A–D (1–4) and two new prenyl flavonoid derivatives wushepimedoside E–F (5–6), and one know analog epimedkoreside B (7) were isolated from biotransformation products of the aerial parts of Epimedium wushanense. Their structures were elucidated according to comprehensive analysis of HR-MS and NMR spectroscopic data, and the absolute configurations were assigned using experimental and calculated electronic circular dichroism (ECD) data. The regulatory activity of compounds 1–7 on the production of testosterone in primary rat Leydig cells were investigated, and 4 and 5 exhibited testosterone production-promoting activities. Molecular docking analysis suggested that bioactive compounds 4 and 5 showed the stable binding with 3β-HSD and 4 also had good affinity with Cyp17A1, which suggested that these compounds may regulate testosterone production through stimulating the expression of the above two key proteins.

    Abstract Gypenosides (Gps) are the major bioactive components in Gynostemma species. They include neutral Gps and acidic malonylgypenosides (MGps). MGps are abundant in Gynostemma species and can be transformed into corresponding Gps via extraction, concentration, and drying. If only the Gps were quantified and MGps were ignored, the quality of Gynostemma species would be underestimated. This study aimed to develop a sample preparation method involving demalonylation and ultrahigh-performance liquid chromatography-charged aerosol detector (UHPLC-CAD) analysis to determine the contents of gypenoside XLIX (Gp XLIX) and gypenoside A (Gp A). First, the optimized ultrasonic extraction method was established to extract G. longipes powder ultrasonically. Then, the extracted solution was put into a closed container (centrifuge tube) and heated in a water bath at 95 °C. Then, MGps were converted into corresponding Gps. The proposed preparation method was compared with the other three methods, including water bath reflux heating, alkali hydrolysis, and extraction of heated powder, and was shown to exhibit higher conversion and better convenience. Subsequently, an UHPLC-CAD method was established and validated. Gp XLIX and Gp A showed excellent linear correlations between 15.55 and 248.8 μg/mL and 24.10-385.5 μg/mL, respectively (R
