Embodiment 1

[0029] Embodiment 1 gardenia extract and its preparation

[0030] Preparation:

[0031](1) Add 2 times the volume of 80% ethanol to soak the gardenia for 0.5 hours, reflux at 60°C for 3 hours, filter, and collect the filtrate; after filtering, add 2 times the volume of 80% ethanol to extract for 3 hours at 60°C. Filter, combine the filtrates, concentrate until there is no alcohol smell, and obtain Gardenia extract;

[0032] (2) Gardenia extract was added to AB-8 macroporous resin column, 2 times column volume was eluted with water, and the eluent was discarded; 3 times column volume was eluted with 8% ethanol, and the eluent was discarded; Elute with 40% ethanol by volume, collect the 40% ethanol eluate, concentrate under reduced pressure, and dry to obtain the product.

[0033] Content detection:

Abstract

The invention relates to a gardenia extract, in particular to a gardenia extract for treating hyperbileacidemia. The gardenia extract comprises geniposide, genipin 1-beta-D-gentiobioside, 6''-p-coumaroyl genipin gentiobioside, scandoside methyl ester, geniposidic acid, gardenoside and gardenoside, and is prepared through ethanol extraction and macroporous resin purification. The gardenia extract is capable of significantly reducing the bile acid level in the blood of rats, has a good effect on the treatment of hyperbileacidemia, and can be applied to the preparation of drugs for treating hyperbileacidemia.

Description

technical field [0001] The invention relates to a gardenia extract and its preparation and application, in particular to a gardenia extract for treating hyperbiliary acidemia and its preparation and application. Background technique [0002] Gardenia is the fruit of Rubiaceae gardenia, also known as yellow gardenia, mountain gardenia, and white toad. The fruit of gardenia is a traditional Chinese medicine, which belongs to the first batch of medicinal and edible resources promulgated by the Ministry of Health. [0003] The research on gardenia is very extensive. Previous pharmacodynamic studies have shown that gardenia has the following effects: (1) Effects on liver function: gardenia can reduce serum bilirubin content; Red pigment level can prevent fulminant hepatitis caused by galactosamine, and can reduce serum bilirubin, alanine aminotransferase and alkaline phosphatase in rats poisoned by a-naphthyl isothiocyanate. (2) Effect on bile secretion: Gardenia jasmine has ch...
