珍珠草在配方入药前经过炮炙,炮炙过程中矶松素等醌类化合物散失。作者通过对比实验说明,珍珠草经过炮炙有88.64%的总提取物散失,其中矶松素占总提取物的87.31%,这作为副产品是很有价值的。另外,珍珠草经白酒处理对于矶松素等醒类物质的提取可以缩短时间,提高收率。珍珠草中氢氰酸在炮炙前后的量变有待进一步研究。 Pearlgrass was bombarded before formulating medicines, and terpenes and other terpenoids were lost during the process. The authors demonstrated that 88.64% of the total extracts of P. serrata had been lost through the artillery borer. Among them, the isocorytonine accounted for 87.31% of the total extract. This is valuable as a by-product. In addition, pearl grass by liquor treatment for awakening and other awakening substances can shorten the extraction time, improve yield. The amount of hydrocyanic acid in pearl grass before and after the artillery blasting needs further study.
