Abstract

The invention discloses a method for extracting geniposidic acid and verbascoside in semen plantaginis by an ASE (Accelerated Solvent Extraction) method. The method is shorter in extraction time and good in repeatability, and belongs to the field of extraction of the geniposidic acid and the verbascoside. The method comprises the following steps: crushing a semen plantaginis sample, enabling the crushed semen plantaginis sample to pass through a second sieve, taking 1g of the semen plantaginis sample powder and mixing the 1g of the semen plantaginis sample powder with 1g of diatomite; charging a mixture obtained in the first step into an ASE extraction pool in which a fiber filtration film is putted, and adding the diatomite to be parallel to a pool opening; extracting with methanol, and fixing the volume of an extracting solution to be 50ml by using the methanol. The method disclosed by the invention can replace a pharmacopoeia method for extracting the geniposidic acid and the verbascoside in the semen plantaginis and determining the contents.

Description

technical field [0001] The invention belongs to the field of extracting geniposide and verbascoside, in particular to an ASE method for extracting geniposide and verbascoside from seeds of plantago. Background technique [0002] "Chinese Pharmacopoeia" 2015 Edition Part I Preparation method for the test product: Preparation of the test product solution Take about 1g of the powder of this product (passed through a No. 2 sieve), accurately weigh it, put it in a stoppered conical flask, and accurately add 60% methanol 50ml, weighed, heated to reflux for 2 hours, allowed to cool, weighed again, made up for lost weight with 60% methanol, shaken well, filtered, and obtained the filtrate. [0003] This method takes a long time to reflow and requires a high level of expertise for technicians. Contents of the invention [0004] In view of the above-mentioned deficiencies, the present invention aims to provide a method for extracting geniposide and verbascoside in Semen psyllium by...
