    Abstract Three new C-geranylated flavonoids named as paucatalinones L (1), M (2), and N (3) were isolated from the seeds of Paulownia catalpifolia T. Gong ex D.Y. Hong. Their structures were determined by means of UV, IR, MS, NMR and CD techniques. Among them, paucatalinone N (3) was the fifth C-geranylflavone derivative obtained from Paulownia genus, and its geranyl variation was firstly displayed in Paulownia C-geranylated flavonoids. Moreover, Compounds 1 and 3 showed good inhibitory effects on xanthine oxidase.

    Abstract Six undescribed C-geranylated flavonoids, including five C-geranylflavanones named as paucatalinones F - J, one C-geranylflavonol named as paucatalinone K, along with seven known geranylated flavanones, were isolated from the fruit peel of Paulownia catalpifolia T. Gong ex D.Y. Hong. Their structures were elucidated distinctly according to their UV, IR, MS, NMR, and CD data. Among them, two compounds were substituted with unusual modified geranyl groups, namely paucatalinone F with an oxygenated cyclogeranyl substituent and paucatalinone H with a terminal pyranoid geranyl substituent. Furthermore, the protective effects on human umbilical vein endothelial cells (HUVECs) injury induced by H

    Abstract Three new geranylated flavonoids, including two geranylflavones (1, 2) and one geranylflavonol (3), named as paucatalinone C–E, were isolated from the fruit peel of P. catalpifolia T. Gong ex D.Y. Hong. Their structures were determined by means of UV, IR, MS, and NMR techniques. To our known, geranylflavone or geranylflavonol was the first isolation from the genus Paulownia. These isolated geranylated flavonoids displayed good antioxidant effects on DPPH and the senescent human embryonic lung diploid fibroblasts cells (2BS cells) induced by H2O2. The geranyl substituent may be an important factor for the cellular radical-scavenging effect because of its lipophilic character.

    Abstract: ... Gong-Hou mud volcanoes in eastern Taiwan to uncover the spatial distributions of biogeochemical ...

    Abstract This study analyzed cored sediments retrieved from sites distributed across a transect of the Lei-Gong-Hou mud volcanoes in eastern Taiwan to uncover the spatial distributions of biogeochemical processes and community assemblages involved in methane cycling. The profiles of methane concentration and carbon isotopic composition revealed various orders of the predominance of specific methane-related metabolisms along depth. At a site proximal to the bubbling pool, the methanogenic zone was sandwiched by the anaerobic methanotrophic zones. For two sites distributed toward the topographic depression, the methanogenic zone overlaid the anaerobic methanotrophic zone. The predominance of anaerobic methanotrophy at specific depth intervals is supported by the enhanced copy numbers of the ANME-2a 16S rRNA gene and coincides with high dissolved Fe/Mn concentrations and copy numbers of the Desulfuromonas/Pelobacter 16S rRNA gene. Assemblages of 16S rRNA and mcrA genes revealed that methanogenesis was mediated by Methanococcoides and Methanosarcina. pmoA genes and a few 16S rRNA genes related to aerobic methanotrophs were detected in limited numbers of subsurface samples. While dissolved Fe/Mn signifies the presence of anaerobic metabolisms near the surface, the correlations between geochemical characteristics and gene abundances, and the absence of aerobic methanotrophs in top sediments suggest that anaerobic methanotrophy is potentially dependent on iron/manganese reduction and dominates over aerobic methanotrophy for the removal of methane produced in situ or from a deep source. Near-surface methanogenesis contributes to the methane emissions from mud platform. The alternating arrangements of methanogenic and methanotrophic zones at different sites suggest that the interactions between mud deposition, evaporation, oxidation and fluid transport modulate the assemblages of microbial communities and methane cycling in different compartments of terrestrial mud volcanoes.

Among them, two compounds were substituted with unusual modified geranyl groups, namely paucatalinone F with an oxygenated cyclogeranyl substituent and paucatalinone H with a terminal pyranoid geranyl substituent. Furthermore, the protective effects on human umbilical vein endothelial cells (HUVECs) injury induced by H2O2 were evaluated, and paucatalinone F showed the most potential activity. The bioactive results suggested that the geranyl substituent may be an important factor for restraining oxidative HUVECs damage and Paulownia C-geranylated flavonoids might have the potential for preventing cardiovascular complications.

    Abstract Lei gong pao zhi lun (Master Lei's Discourse on Processing of Chinese Materia Medica) collated by Zhang Ji, and printed by Zhang's Yisheng Tang in Chengdu in 1932 was the first collated edition. Its original edition was not Jing shi zheng lei bei ji ben cao (Classified Materia Medica from Historical Classics for Emergency) of the Song Dynasty, but was Xiu shi zhi nan (Instruction for Drug Processing) and Lei gong pao zhi yao xing jie (Explanation on Master Lei's Properties of Drugs Processing) of the Qing Dynasty. The contents of this collated edition was far from Lei gong pao zhi lun with many mistakes, and was not the best edition to study Lei gong pao zhi lun.
