鹿衔草化学成分的研究(第1报)

STUDIES ON THE CHEMICAL CONTITUENTS OF PYROLA CALLIANTHA

从鹿衔草中分离得到8种结晶,其中5种经分析鉴定为:高熊果酚甙(homoarbutin,1),肾叶鹿蹄草甙(renifolin,2),金丝桃甙(hyperin,3),2″-0-没食子酰基金丝桃甙(2″-0-galloylhyperin,4)和6′_0-没食子酰基高熊果酚甙(6′-0-galloylhomoarbutin,5)。除1外,其它成分均系在鹿衔草中首次分得。4是鹿衔草的主要成分具有很强的单宁活性,并具有扎氧化、清除脂质过氧自由基和抑制脂质过氧化活性。

8 compounds have been isolated from the Pyrola calliatha H.And- res.5 structures of them were elucidated by spectral data as follows: homoabrutin (1),renifolin (2),hyperin (3),2″-0-galloylhyperin (4), 6′-0-galloylhomoarbutin (5) Except (1),other compounds were isola- ted in the plant at the first time.The important contituent of the plant is structure (4),which has heavier tannin activity,antioxidation, getting rid of lipid peroxide free-radical and inhibting lipid peroxide activity。
