1.根据药典记载,山道年与甘汞的测定,需取用雨份样品分别操作,实际上如取一份样品也可以:用氯仿提取液作山道年含量测定,残渣作甘汞测定。这样即可节省一份样品,同时也节省了重复操作所需用的时间、药品,因为药典上记载测定甘汞时,仍需用氯仿提尽山道年的。2.抽提山道年的氯仿液,可不必用热氯仿或放在水浴上加熟提取,直接将研碎称得的样品放置250ml 烧杯内,加冷氯仿反覆抽提即可。因为山道年在氯仿中的溶解度约为1∶2,300mg 山道年用约150ml 氯仿分多次提取,是可以提尽的。这样一方面可以避免
1. According to the records of the pharmacopoeia, the determination of the year of the mountain and the calomel requires the separate operation of the rain samples. In fact, if a sample is taken, the content of the annual trace of the trace can be determined by using the chloroform extract and the residue as calomel. This will save a sample, but also save the time required for repeated operations, drugs, because the pharmacopoeia records of calomel, chloroform still need to mention the years. 2. Extracting Ching Road, the chloroform solution, may not need to use hot chloroform or on the water bath plus cooked extraction, the crushed directly to the sample placed 250ml beaker, add cold chloroform extraction can be repeated. Because of the year of the year in the chloroform solubility of about 1: 2, 300mg Hill Road with about 150ml chloroform sub-multiple extraction can be made. This can be avoided on the one hand
