甜叶菊原产于南美巴拉圭,其甜度为砂糖的数百倍,多在饮料、食品中使用。甜叶菊还具有抗轮状病毒、降压、治疗Ⅱ型糖尿病等多种药理作用。甜叶菊茎的发酵提取物可减轻过敏症状,但有关药理学研究尚少。本次探讨了甜叶菊发酵提取物的抗组胺作用。 材料与方法:①试验材料的制备:将甜叶菊的干燥叶、茎粉碎,取干燥粉末1kg溶于10L水中,90～100℃搅拌提取1h,逐渐冷却至50℃,用150～200目筛过
Stevia is native to Paraguay, South America, and its sweetness is several hundred times that of sugar. It is used in beverages and foods. Stevia also has a variety of pharmacological effects such as anti-rotavirus, blood pressure, and type II diabetes. The fermented extracts of stevia stems reduce allergic symptoms, but there are few pharmacological studies. This study explored the antihistamine effects of Stevia fermentation extracts. Materials and methods: 1 Preparation of test materials: Dry leaves and stems of stevia were crushed, and 1kg of dry powder was dissolved in 10L of water. The mixture was stirred and extracted at 90-100°C for 1 hour, gradually cooled to 50°C, and sieved with 150-200 mesh.
