Embodiment 1

[0049] 1.1 Qingliu Willow Medicine Treatment: Qingqi Liu dry leaf (10kg), crushing after 70% ethanol 120 ° C, heat reflux extraction (100L; 2 × 2H), concentrated to extract the extract at 60 ° C, concentration time of 2 days. The immersion paste was further dispersed with water, extracted with dichloromethane, ethyl acetate, n-butanol, extracted 3 times each time, extract 60 ° C, concentration time of 24 hours, extraction concentration of different polarity parts, respectively liquid. The dichloromethane site is mainly Damartane tetracelial triterpenoid compound, labeled QQL-ST, and the n-butanol site is mainly flavonoid compound, and is labeled as QQL-HT.

Embodiment 2

[0087] Study on the effect of improving gout in the same life and Damartane tetracene triterpenoids

[0088] 2.1 Anti-pain-resistant arthritis

[0089] 2.1.1 Experimental method:

[0090] Study on the effect of QQL-ST anti-pain: 40 quarantine is 40, male, according to the body weight, randomly divided into 4 groups, respectively, the normal control group, the model control group, the Qingliu dichloromethane active site group , Gouting capsule group, 10 animals per group. Each group was given a corresponding liquid, normal control group and model control group gave a given amount of pure water. 1 time a day, for 8 days. In addition to the normal control group, the remaining groups were treated 30 minutes afterwards, and the SD rats were inhaled with isoflurane (induced by 0.25% to 2%), and the bilateral rear leg knee joint was inhaled. Shaving around, medical alcohol disinfection skin, light curved knee, synthetic side, needle with a syringe No. 6, 0.5ml of uricate solution (25 mg ...

Abstract

The invention relates to a cyclocarya paliurus extract, in particular to a cyclocarya paliurus dichloromethane active site and a dammarane tetracyclic triterpenoid compound as well as an extraction method and application thereof. The structure of the cyclodammarane tetracyclic triterpenoid compound is shown as a formula I or a formula II. The dammarane tetracyclic triterpenoid compound 1-26 and the dichloromethane active part of cyclocarya paliurus have good effects in preparation of activity tests for improving gout and reducing uric acid, and are expected to become a new generation of medicines for improving gout and reducing uric acid.

Description

Technical field [0001] The present invention relates to extracts of Qingqiao, in particular, involving Qingli Liutchloromethane active parts and Darmane tetracycline triterpenoid compounds (including 3, 4-cracked rings and non-cracking loops) and their extraction Method and application. Background technique [0002] Qingliuhua [cyclocaryapaliurus (BATA1) iljinsk] Juglaruiaceae, Qingliracea, is a unique single plant, widely distributed in Anhui, Jiangsu, Zhejiang and other places. Since the 1980s, experts and scholars at home and abroad mainly conducted a lot of research on the cultivation, chemical composition, bioactivity and product development research of Qingqiao willow. The results show that the Qingliu will will willow has a variety of physiological activity and pharmacological functions for human body. [0003] Titerpenoids is a class of important natural products in natural distribution and variety of structural types, with hypoglycemic step-down, anti-inflammatory, lower...
