大花罗布麻叶(Poacgnam hendlrsonii(Hook.f.)Woodson)的乙醇提取物(P.H.I)可延长果蝇寿命,促进动物免疫功能,降低血清过氧化脂质水平,减少人工白内障的形成。体外试验有明显的抗自由基作用,经6个月长期毒性试验未见有明显的毒性反应,也未见有致突变现象,结果提示大花罗布麻叶有可能作为一种安全而有效的延缓衰老药物。
The ethanol extract (P. H. I) of Poacgnam hendlrsonii (Hook.f.) Woodson leaves prolongs the lifespan of fruit flies, promotes animal immune function, lowers serum lipid peroxide levels, and reduces the formation of artificial cataracts. In vitro tests showed significant anti-free-radical effects. There was no obvious toxicity response and no mutagenesis after 6 months of long-term toxicity test. The results suggested that Daphne genifolia leaves may act as a safe and effective anti-aging drug.
