本文对采自黑龙江省黑河地区林场的桦树液进行了化学成分及保健作用的研究,测得含有干物质0.77～0.85%、还原糖1.14%,以及钙、磷、锌、硒等15种微量元素。动物实验结果初步证明,桦树液能增进幼小动物发育、促进动物生长,增重免疫器官,抗疲劳,且常规服用安全。测得口服LD_(50)及其可信限为45.941±8.650g/kg。连续应用后对脏器功能及形态无不良反应。
In this paper, the chemical constituents and health effects of birch sap collected from the forest farm in Heihe, Heilongjiang Province were studied. The contents of dry matter 0.77 ~ 0.85%, reducing sugar 1.14% and 15 trace amounts of calcium, phosphorus, zinc and selenium element. Preliminary results of animal experiments show that birch fluid can promote the development of young animals, animal growth, weight gain immune organs, anti-fatigue, and regular taking safety. Measured oral LD_ (50) and its confidence limit of 45.941 ± 8.650g / kg. Continuous application of visceral function and morphology without adverse reactions.
