Abstract

A method using liquid chromatograph to measure content of Rabdosia rubescens A element and rosemary acid in high efficiency includes preparing conditions for test, preparing control sample solution, preparing tested sample solution and carrying out measurement.

Description

technical field [0001] The invention relates to a method for determining the contents of oridonin A and rosmarinic acid in Rubescens orioides and its preparations. Background technique [0002] Donglingcao is a plant of the family Lamiaceae, the genus Camellia. Sweet and bitter in taste, slightly cold in nature, it has the functions of clearing away heat and detoxification, reducing inflammation and relieving pain, invigorating the stomach and activating blood circulation. For the treatment of pyretic carbuncle, blood stasis syndrome and other diseases. [0003] The chemical constituents in Rubescens sativa are very complex, and Rubescensin A and rosmarinic acid are effective active ingredients of Rubescens sativa and its preparation extracts. [0004] Oridonin is an anticancer drug, which has obvious therapeutic effects on various cancers and has few side effects. In vivo experiments proved that Rubescensine A injected intraperitoneally at 10 mg / kg had obvious anti-tumor...
