山药不同炮制品成分比较

A Comparative Study on Chemical Constituents in Different Processed Products of Dioscorea opposita

采用药典收载的方法和薄层扫描法,分别对山药及其3种不同炮制品水溶性浸出物、醇溶性浸出物和尿囊素含量进行了定量比较。结果表明,4个样品水溶性浸出物和醇溶性浸出物含量变化基本相似。尿囊素含量则是麸炒山药最高,炒山药最低。说明水溶性浸出物、醇溶性浸出物含量与尿囊素含量之间无相关性。可考虑增加尿囊素含量指标来控制山药炮制品质量。

The quantitative comparisons of Water-soluble extract, alcohol-soluble extract and allantoin in crude and three processed products of Dioscorea opposita is carried out by the method recorded in Pharmacopoeia and TLCS respectively. As a result,the changes of water-soluble extract and alcohol-soluble extract during the four samples are similar. It is the hightest in the processed product stir-fried with soil and lowest in the crude. But for allantoin.it is the highest in the processed product stir-fried with wheat bran and lowest in that stir-fried with no material.It is suggested that the contents between water-soluble extract,alcohol-soluble extract and allantoin are not interrelated. It shall be considered to increase the content of allantoin as a quality control index to control the quality of the processed products.
