桑根活性成分反式二苯乙烯抗糖尿病作用研究 总被引:1,自引:0,他引:1
为探讨桑根中提取分离的2,5'-羟基反式二苯乙烯-4,3'-二-β-D-吡喃葡萄精苷(DGTS)的抗糖尿病作用,测定DGTS对α-葡萄糖苷酶和α-淀粉酶的抑制活性,观察DGTS对HIT-T15细胞的影响.结果表明:DGTS显示很强的α-葡萄糖苷酶的抑制作用,当DGTS浓度为250 μg·mL-1时,α-葡萄糖苷酶抑制率为60%;DGTS对α-淀粉酶也显示很强的抑制作用,当DGTS浓度为5 μg·mL-1时,α-淀粉酶抑制率为39%,高于50μg·mL-1的阿卡波糖.DGTS对链脲佐菌素引起HIT-T15细胞的损伤具有保护作用.证明DGTS具有抗糖尿病作用. 相似文献

Two diarylheptanoids, 1,7-bis-(3,4-dihydroxyphenyl)-heptane-3-one-5-O-β-d-xylopyranoside (I) and 1,7-bis-(3,4-dihydroxyphenyl)-heptane-5-O-β-d-xylopyranoside (II), were isolated from the bark of Alnus hirsuta. Compounds I and II exhibited strong antioxidative activity against 1,1-diphenyl-2-picrylhydrazyl radicals, with IC50 values of 8.36 ± 0.54 and 8.67 ± 1.46 μM, respectively. In addition, we demonstrated that compounds I and II inhibited the
production of nitric oxide and reactive oxygen species and the expression of proinflammatory molecules such as inducible nitric
oxide synthase and cyclooxygenase-2 in lipopolysaccharide-induced macrophages. According to our results, the two diarylheptanoids
isolated from the bark of A. hirsuta exhibited significant antioxidative activity and anti-inflammatory effects and may be useful in the pharmaceutical industry
for alleviating oxidative stress. 相似文献
