摘要:

目的:研究党参多糖(CPPS)抗氧化及延缓衰老的作用。方法:选用D-半乳糖(D-gal)诱导建立衰老模型,CPPS分别按高剂量(250mg/(kg·d))、中剂量(150mg/(kg·d))、低剂量(50mg/(kg·d))连续灌胃50d,观察CPPS对小鼠脑、肝脏组织超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)、丙二醛(MDA)的影响;用CPPS高剂量(0.08%)、中剂量(0.016%)、低剂量(0.0032%)培养果蝇,进行果蝇生存实验。结果 CPPS可以显著提高SOD、GSH-Px的活性(P<0.05或P<0.01),降低MDA含量(P<0.05)。高、中剂量CPPS都显著提高果蝇平均寿命和最高寿命(P<0.05)。结论 :CPPS具有一定抗氧化延缓衰老的作用。

Abstract:

Objective: To explore the effect of Codonopsis pilosula polysaccharide (CPPS) on oxidation and senescence
resistance. Methods: Aging mouse models were induced by injection of D-galactose. CPPS at high, middle and low doses were
intragastrically administered to aging model mice. Malondialdehyde (MDA) content, and glutathione peroxidase (GSH-Px) and
superoxide dismutase (SOD) activities in brain and liver homogenates were measured. According to different polysaccharide
doses, the survival of fruit flies was also investigated. Results: CPPS could improve the activities of SOD and GSH-Px (P < 0.05,
P < 0.01) and decrease the content of MDA in brain and liver homogenates (P < 0.05). The average life span and maximum
life span in the high and middle dose groups were significantly higher than those in the control group (P < 0.05). Conclusion:
CPPS has obvious roles in anti-oxidation and senescence resistance.

Key words: Codonopsis pilosula polysaccharide (CPPS), anti-oxidation, senescence resistance
