摘要:

响应面分析法优化海蓬子皂苷提取工艺,初步鉴定海蓬子皂苷的结构,并探讨其对α-葡萄糖苷酶与胰脂肪 酶的体外抑制活性。海蓬子皂苷最佳提取条件为料液比1∶27(g/mL)、乙醇体积分数62%、超声时间30 min。在此 条件下,海蓬子皂苷的提取量为10.14 mg/g;显色反应和红外光谱初步分析表明,海蓬子皂苷为四环三萜类皂苷; 体外实验表明,经纯化的海蓬子皂苷提取物对α-葡萄糖苷酶和胰脂肪酶均有较强抑制作用,并呈剂量效应,对α-葡 萄糖苷酶、胰脂肪酶的抑制率分别达到68.20%和84.28%。该结果提示海蓬子皂苷可能具有阿卡波糖样的降血糖机 制以及降血脂的功效。

Abstract:

Response surface methodology was used to optimize the extraction process for saponins from young leaves
of Salicornia herbacea. The saponions extracted were structurally characterized and evaluated for inhibitory effect on
α-glucosidase and pancreatic lipase in vitro. Our results indicated that the optimal extraction conditions were material-toliquid
ratio of 1:27 (g/mL), ethanol concentration (V/V) of 62%, and ultrasonification time of 30 min. Under these extraction
conditions, maximum yield of saponins of 10.14 mg/g was obtained. Color reaction and infrared spectral analysis showed
that the basic structure of saponins from Salicornia herbacea was tetracyclic triterpene saponin. The purified saponins had a
strong inhibitory effect on both α-glycosidase and pancreatic lipase in vitro in a dose-dependent manner, and the maximum
inhibitory rates were 68.20% and 84.28%, respectively. These results suggest that saponins from Salicornia herbacea may
have similar hypoglycemic mechanism and hypolipidemic effect to acarbose.
