The aim of this study was to elucidate the relationship between the chemical components and the growth of S. horneri as recyclable resource for a sustainable future. S. horneri at an ocean depth of 5 m grew rapidly. The biomass was abundant from January until April. After maturation and gamete release at the middle of April, plant senescence began occurring, and only short plants remained at the sea bottom. On the other hand, S. horneri at an ocean depth of 1 - 2 m grew slowly and could be harvested until early June. The protein, lipid and total dietary fiber content of S. horneri at an ocean depth of 5 m showed apparent gender-based differences.展开更多
研究以海藻膳食纤维为主,传统降脂中药山楂、绞股蓝、泽泻为辅的功能食品的降血脂作用。参考卫生部保健食品辅助降血脂功能评价方法,以高脂饲料建立高脂血症小鼠模型,灌胃给予含不同成分的复合物(海藻膳食纤维高、中、低剂量组,复合物...研究以海藻膳食纤维为主,传统降脂中药山楂、绞股蓝、泽泻为辅的功能食品的降血脂作用。参考卫生部保健食品辅助降血脂功能评价方法,以高脂饲料建立高脂血症小鼠模型,灌胃给予含不同成分的复合物(海藻膳食纤维高、中、低剂量组,复合物Ⅰ、Ⅱ、Ⅲ组,辛伐他汀组,正常对照组和模型组灌胃生理盐水)。4周后,测定血清总胆固醇(total cholesterol,TC)、甘油三酯(triglyceride,TG)、高密度脂蛋白胆固醇(high density lipoprotein cholesterol,HDL-C)以及低密度脂蛋白胆固醇(low density lipoprotein cholesterin,LDL-C)水平,计算肝脏系数,苏木精-伊红染色观察肝脏脂肪变性程度。结果表明:海藻膳食纤维能显著降低高脂血症小鼠血清TC、TG及LDL-C水平,升高HDL-C水平;且加入少量药食同源的中药(绞股蓝提取物和泽泻提取物)后的复合型海藻膳食纤维能使高脂小鼠血脂水平更接近正常值。说明复合型海藻膳食纤维功能食品有较好的降血脂作用。展开更多
