目的：研究无瓣海桑（Sonneratiaapetala）果实提取物对D-半乳糖致衰老小鼠抗氧化能力的影响。方法：选用D-半乳糖（D-gal）诱导建立衰老小鼠模型，并分别灌胃无瓣海桑果实醇提物、乙酸乙酯提取物和正丁醇提取物，观察无瓣海桑果实各提取物对衰老小鼠血清、心脏和肝脏组织中超氧化物歧化酶（SOD）、谷胱甘肽过氧化物酶（GSH-Px）、丙二醛（MDA）的影响。结果：与模型组相比，无瓣海桑果实提取物可以有效提高衰老小鼠体内SOD、GSH-Px酶活力，降低MDA含量（P < 0.05）。结论：无瓣海桑果实提取物能有效提高D-半乳糖致衰老小鼠体内抗氧化能力从而达到延缓衰老的作用。

To study the effect of extracts of Sonneratiaapetala fruit on the antioxidant capacity of aging mice induced by D-galactose. D-galactose (D-gal) was selected to establish a mouse model of aging. The aged mice were fed with extractsof Sonneratiaapetala fruit , alcohol extracts, and ethyl acetate extracts respectively. The effects of extracts on superoxidedismutase (SOD), glutathione peroxidase (GSH-Px) and malondialdehyde (MDA) in serum, heart and liver of aging micewere observed. The experimental results show that, compared with the model group, the extract of Sonneratiaapetala fruitcan effectively increase the activity of SOD and GSH-Px enzymes and reduce the content of MDA in aging mice (P <0.05). The results showed that the extract of Sonneratiaapetala fruit extract can effectively improve the anti-oxidationability of aging mice induced by D-galactose, so as to achieve the effect of delaying aging.
