Grosvenorine is the majorflavonoid compound of the fruits of Siraitia grosvenorii (Swingle) C. Jeffrey, a medical plant endemic to China. In the present study, for the first time, the grosvenorinemetabolism in an in vitro simulated human gastrointestinaltract (including artificial gastric juice, artificial intestinal juice and intestinal flora), as well as its pharmacologicalactivities (including
Grosvenorine 是罗汉果(Siraitia grosvenorii (Swingle) C. Jeffrey)果实中的主要黄酮类化合物,这是一种中国特有的药用植物。本研究首次在体外模拟人体胃肠道(包括人工胃液、人工肠液和肠道菌群)中的罗汉素代谢及其药理活性(包括抗补体、抗菌和抗氧化)活动),进行了调查。结果表明,罗汉果被人体肠道菌群代谢;其四种代谢物通过半制备型 HPLC 分离,并通过 NMR 鉴定为山柰素、afzelin、α-鼠李糖异核素和山奈酚。进一步的药理评价表明,罗汉果具有良好的抗菌和抗氧化活性,其代谢物具有更强的活性。虽然罗夫纳林没有明显的抗补体活性,但其代谢物显示出有趣的活性。本研究表明,肠道细菌在罗汉果的胃肠道代谢中起重要作用,并显着影响其药理活性。
