Abstract:
Object To explore the regularity of microwave extraction (ME) on Chinese medicines in different morphological structure and different polar compositions. Methods Anthraquinone in Radix et Rhizoma Rhei (RRR), Semen Cassiae (SC), cholorogenic acid in Flos Lonicerae, baicalin in Radix Scutellariae were determined as index compositions by HPLC. The extraction rate was measured by orthogonal design. Results ME selectivity to different anthraquinone in RRR is not significant, while at the same temperature, the extraction rates of emodin, chrysophanol, physcion in RRR are higher than those in SC. Conclusion The ME selectivity to the different morphological structure of Chinese medicines is obvious, but to the different polar compositions is not distinct.
