The invention provides a method for detecting the quality of plumeria rubra L. medicinal material or plumeria rubra L. extract. The method comprises the following steps: detecting the quality of dried flowers and extract of plumeria rubra L. of apocynaceae plumeria L. plants by virtue of an HPLC method; and determining by adopting the high performance liquid chromatography method, wherein chromatographic conditions are as follows: octadecyl bonded phase silica gel is used as a filling agent, acetonitrile-0.5% phosphoric acid water (at a ratio of 8:92) is used as a mobile phase and the detection wavelength is 210nm. The inventor researches and finds that 15-demethylated plumieride is one of iridoid glycoside components in plumeria rubra L. and the content is relatively high; and the method can be used for quality detection and control of the flowers of plumeria rubra L. According to the method provided by the invention, the content of 15-demethylated plumieride in plumeria rubra L. is determined by adopting the HPLC method for the first time, and scientific basis is provided for quality standards of plumeria rubra L.
Description
technical field [0001] The invention relates to a method for detecting the quality of frangipani medicinal material or frangipani extract. Background technique [0002] Plumeria, also known as Gardenia Burmese, Plumeria japonica, Plumeria japonica, is the dried flower of Plumeria rubra L. It is native to tropical America and is now widely planted in tropical regions of the world. In my country, it is mainly produced in Guangdong, Fujian, Guangxi, Hainan and other places. It is sweet, light, and cool in nature. It has the effects of clearing heat, promoting dampness, stopping dysentery, moistening the lungs, relieving cough and detoxifying. It is a commonly used herbal medicine in the Lingnan area, and it is also one of the main raw materials of Guangdong herbal teas. For example, the famous herbal teas sold in the market "Wanglaoji herbal tea" and "Wuhua tea" all use frangipani as the main raw material. With the development of the herbal tea industry, the demand for frangi...
