Problems solved by technology

[0005] At present, the commonly used methods for the analysis and detection of fatty acid compounds and / or sterol compounds include gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). , its disadvantages are side reactions such as oxidation, decomposition and isomerization during the esterification process, and it is difficult to ensure complete esterification, which increases the analysis time during the esterification process and complicates the analysis method, because both free fatty acids and fatty acid derivatives are Derived into fatty acid methyl esters, etc., these methods cannot be used to directly determine the content of non-derivatized fatty acid compounds and / or sterol compounds, and are not suitable for detection in the production process

Abstract

Disclosed is a detection method of fatty acid compounds and / or sterol compounds in rape bee pollen, which is characterized by comprising: a) pretreating the rape bee pollen to-be-measured to get rape bee pollen extracts; and b) detecting fatty acids and / or sterol compounds in rape bee pollen extracts by HPLC-ELSD and HPLC-UV method. The detection method of fatty acid compounds and / or sterol compounds in rape bee pollen is high in controllability and low in energy consumption, and is conductive to industrial production.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine pharmacy, and in particular relates to a method for detecting fatty acid compounds and / or sterol compounds in rape bee pollen. Background technique [0002] Clinical practice at home and abroad has proved that pollen and its preparations are ideal drugs for the treatment of prostate diseases. Li Yonghui (Li Yonghui. Research on the pharmacodynamic substance basis of vegetable pollen against benign prostatic hyperplasia. Master's degree thesis of Shanghai Institute of Pharmaceutical Industry (D), 2009) reported in the literature that rape bee pollen, vegetable pollen, corn pollen, For pine pollen and sunflower pollen, more than 10 kinds of pollen of different varieties and different production areas were collected in major production areas of the country. Anti-inflammatory and anti-testosterone propionate-induced hyperplasia in rats were used as pharmacological screening models. Aspirin,...
