为了寻找一些分布更加普遍、蕴藏量更大的含小蘗硷植物,作为提取小蘗硷的后备物资,现发现“三颗针”的根、茎里面,含有很多的小蘗硷,尤以根皮含量更多。作者测定其茎皮中含小蘗硷为2.90%,根皮中含量为10.60%。四川省越西医院已经正式进行生产,根据该院采用水提法提取结果,每百斤“三颗针”茎皮能提取盐酸小蘗硷3.8斤;根部的木质,靱皮部能提取0.5斤,根皮因含量高,该院已直接用它磨成细粉供口服,目前已在临床上大最应用,效果一般良好。近来又用它制成了浓度为0.7%的针剂,给家兔作了一次静脉注射,除体温较注射向前升高4℃外;呼吸活动都很正
In order to find some of the more widely distributed and relatively large reserves of plants containing barnyardgrass, as a reserve material for the extraction of small pupae, it has been found that the roots and stems of the “three needles” contain a lot of small pupae, especially More root bark content. The authors determined that the bark in the bark was 2.90% and the content in the root bark was 10.60%. The West Vietnam Hospital of Sichuan Province has officially started production. According to the results of the water extraction method used in this hospital, each jin of “three needles” can extract 3.8 kg of hydrochloric acid, and the root of the wood can be extracted 0.5 times. With high content of root bark, the hospital has directly used it to grind fine powder for oral administration. Currently, it has been widely used in clinical practice and its effect is generally good. Recently, it has also been used to make injections with a concentration of 0.7%. An intravenous injection has been given to rabbits, except that the body temperature is 4°C higher than that of injections; breathing activities are very positive.
