不同巴戟天炮制品中糖分布及含量测定.doc

不同巴戟天炮制品中糖分布及含量测定[摘要] 目的：探讨不同巴戟天炮制品的糖含量与入药意义。方法：采用紫外可见分光光度法对净巴戟天、去木芯巴戟天、巴戟天木芯及蒸制后的巴戟天肉中总糖和多糖含量进行测定。结果：净巴戟天总糖为54.83%，多糖为12.09%；去木芯巴戟天总糖含量为59.58%，多糖为13.01%；巴戟天木芯总糖为23.12%，多糖为5.91%；而炮制后的巴戟肉总糖为56.61%，多糖为12.93%，糖的含量比净巴戟天高。结论：巴戟天糖主要分布在肉的部分，不同巴戟天炮制品中其糖的含量存在明显的差异。通过蒸制除去木芯，使药材得到净化，更有利于用药准确。 [关键词] 巴戟天；炮制；总糖；多糖 [中图分类号] R943.1 [文献标识码] C[文章编号] 1674-4721（2011）02（b）-042-02 The distribution of sugar and the determination of different processed products of Morinda TIAN Shaoxiong1, SUN Shuzhou2 (1.Pharmacy of Dashi People′s Hospital, Panyu District of Guangzhou City, Guangzhou 511430, China; 2.Guangzhuo Institute for the Six Drug Control, Guangdong Province, Guangzhou 511400, China) [Abstract] Objective: Discussion the distribution of sugar and the medicine meaning of different processed products of Morinda. Methods: Determine the content of the total sugar and thepolysaccharide in the means of UV-visible spectrophotometry, in which was the pure morinda, the morinda with wood core removed, the wood core of morinda and the steamed morinda meat. Results: The pure morinda total sugar was 54.83% and polysaccharide was 12.09%. The morinda with wood core removed total sugar was 59.58% and polysaccharide was 13.01%. The wood core of morinda total sugar was 23.12% and polysaccharide was 5.91%. The steamed morinda meat total sugar was 56.61% and polysaccharide was 12.93%, which was higher than the pure morinda in the content of sufar. Conclusion: Morinda sugar is mainly distributed in the part of the meat. Different processed products of morinda are significant differences in their sugar content. Steam and remove wood core, which can purify the medicine and make for the drug standard.
