Phytochemical investigation for anti-viral compounds from Okinawan subtropical plants

对亚热带植物(Microtrois Japan onica、Stewartia puocamellia、Cananga odorata、Ardisia ququiegona和Scolopia oldhamii)和一种海绵(Phyllosegia sp.)进行了植物化学研究。共分离得到14个新的三萜类化合物，6个皂苷类化合物，3个木脂素类化合物，11个苯醌类化合物和3个三萜类化合物，14个七叶烯类化合物，这些新化合物的化学结构主要通过波谱分析得到确证。并对其抗流感病毒活性和细胞毒性进行了评价。这些成果的一部分已经发表在几个国际研究期刊上。

Phytochemical investigation of subtropical plants (Microtropis japonica, Stewartia pseudocamellia, Cananga odorata, Ardisia quinquegona, and Scolopia oldhamii) and a marine sponge (phyllospongia sp.) revealed 14 new triterpenes, six saponins, three lignans, 11 benzoquinones together with three triterpens, and 14 scalarene-type sesterterpenes, respectively.The chemical structure of these new compounds were elucidated mainly by spectroscopic analysis. The anti-influenza virus activity and cytotoxicity were also evaluated. Part of these results has been published in several international research journals.
