Study on the Influence of Origin and Vinegar Roasting Process on the Chemical Composition of Nutgrass Galingale Rhizome

To provide a basis for the development of quality standards by studying changes in chemical composition nutgrass galingale rhizome different origins, before and after its vinegar roasting to correct evaluation roasting. A thin-layer method was developed identify water-soluble components aconite. The volatile oil content determined according determination Appendix XVI, Part I 2010 Chinese Pharmacopoeia. from Shandong Anhui higher (1.59 % 1.61 %), while Guangdong lowest (1.14 %). highest beta-sitosterol found (0.017923 %) (0.010893 total flavonoid Henan (0.95381 (0.63565 decreased increased all three groups Nutgrass Galingale Rhizome have better medicinal efficacy use concoction is reasonable.
