槟榔为棕榈科,槟榔属植物槟榔Aracate[Aracatechu L]chu,L的种子。临床主要用于杀虫、行气、利水。其主要有效成分为槟榔碱(arecoline C_8 H_(13) O_2 N),槟榔质地坚硬,在药用时,为了提高有效成分的溶出,故对其进行炮制加工。鉴于槟榔碱具有水溶性、脂溶性和随水蒸发的性质。为了探讨几种炮制方法对槟榔碱含量的影响,我们采用中和法对不同方法炮制的槟榔中槟榔碱含量进行了测定比较。 1 仪器及试剂:分析天平,TG328B,分度值:0.1mg。硫酸,氢氧化钠,AR(锦西化学试剂厂)。乙醚、AR(天津市化学试剂二厂)。
The betel nut belongs to the family Apalate [Aracatechu L]chu,L. It is mainly used for killing insects, gas, and water. The main active ingredient is arecoline (C8H13O2N), and the betel nut has a hard texture. When it is used for medicinal purposes, it is processed to improve the dissolution of active ingredients. In view of the fact that arecoline is water-soluble, fat-soluble and water-evaporating. In order to investigate the effect of several processing methods on the content of arecoline, we used the neutralization method to determine the content of arecoline in betel nut processed by different methods. 1 Instruments and reagents: analytical balance, TG328B, division value: 0.1 mg.
