Problems solved by technology

[0005] Since the crocin components are unstable to light and heat, the crocins in gardenia medicinal materials are mostly extracted by warm soaking method, which takes a long time and low efficiency.
If can provide a kind of extraction method that can effectively extract crocin from Gardenia jasminoides, and the impurity content is little, will be able to bring possibility for reducing the cost of crocin components

Abstract

The invention provides an extracting method of gardenia, comprises the following steps: taking gardenia, adding water, boiling to extract at 50 DEG C at reduced pressure, combining the extracting solution to obtain the gardenia extract. The invention further provides the gardenia extract and a preparation method thereof. The invention further provides a detection method of the gardenia extract. The gardenia extract provided by the invention can be extracted at low-temperature boiling dynamic condition, the crocin I content in the extract is improved, other impurity dissolving-out quantity is reduced, and the extract quality is improved. The detection method provided by the invention is capable of effectively separating a plurality of components in the gardenia extract, the spike is good, the base line is stable, and a reliable basis is provided for controlling the quality of the gardenia extract.

Description

technical field [0001] The invention relates to a gardenia extract, which belongs to the field of pharmaceutical preparations. Background technique [0002] Gardenia is the dried and mature fruit of Gardenia jasminoides Ellis, a Rubiaceae plant. It is a commonly used traditional Chinese medicine in clinical practice. It can relieve fire and trouble, clear away heat and dampness, cool blood and detoxify when taken internally, and has the effects of reducing swelling and relieving pain when used externally. [0003] Gardenia contains active ingredients such as iridoid glycosides (such as iridoid glycosides), terpenoid glycosides (such as crocin) and organic acids. Among them, the crocin components include crocetin Ⅰ, crocin Ⅱ and crocin Ⅲ, etc., which are common compounds contained in gardenia and saffron, a precious Chinese medicinal material, and have inhibitory Pharmacological effects such as growth of tumor cells, treatment of cardiovascular diseases, protection of liver ...
