Embodiment 1

[0015] Example 1: Extraction and preparation of Guangdong Zizhu water extraction sample

[0016] Take the Guangdong purple pearl medicinal material, pulverize (through a 24-mesh sieve), accurately weigh 10 g of the pulverized Guangdong purple pearl powder, put it in a 500ml round bottom flask, and extract twice with distilled water under reflux at an extraction temperature of 98°C. Distilled water 100ml, the first extraction for 1 hour, the second extraction for 3 hours, suction filtration after each extraction, the filtrate and the washing liquid of the washing dregs were combined and concentrated in a 50ml volumetric flask.

Embodiment 2

[0017] Embodiment 2: Extraction and preparation of Guangdong Zizhu dry extract

[0018] Get the Guangdong Zizhu medicinal material, pulverize (cross 24 mesh sieves), accurately weigh 10 g of the pulverized Guangdong Zizhu powder, put it in a 500ml round-bottomed flask, and extract twice with 20% ethanol under reflux at an extraction temperature of 98° C. Add 110ml of 20% ethanol each time, extract for 2 hours for the first time, and extract for 1.5 hours for the second time. Suction filter after each extraction, and combine the filtrate and the lotion of washing dregs into a 50ml volumetric flask.

Embodiment 3

[0019] Embodiment 3: Extraction and preparation of Guangdong Zizhu dry extract

[0020] Get the Guangdong Zizhu medical material, pulverize (cross 24 mesh sieves), accurately weigh 10 g of the pulverized Guangdong Zizhu powder, put it in a 500ml round-bottomed flask, and extract twice with 40% ethanol under reflux. The extraction temperature is 98 ° C. Add 120ml of 40% ethanol each time, extract for 3 hours for the first time, extract for 1 hour for the second time, extract for 2 hours for the third time, suction filter after each extraction, combine the filtrate and the lotion of washing medicine residue into a 50ml volumetric flask middle.

Abstract

The invention provides an extraction method of parts of total flavonoids of callicarpa kwangtungensis chun. The invention is designed against that the Chinese herbal medicine callicarpa kwangtungensis chun is lack of direct extraction method of the parts of the total flavonoids with the good effects. The extraction method adopts 50 percent to 60 percent of alcohol to carry out the reflux extraction of the callicarpa kwangtungensis chun, so the extraction method is not only simple and easy to be operated, but can also achieve the good extraction effects.

Description

technical field [0001] The invention relates to the field of pharmacognosy, in particular to an extraction process of Guangdong Zizhu, a traditional Chinese medicinal material. Background technique [0002] Guangdong Zizhu is mainly used in the treatment of gynecological inflammatory diseases, such as Kanggongyan Tablets, Kanggongyan Granules, Gongfukang Capsules, etc., which are compound preparations with Guangdong Zizhu as the main drug, and have played a very good role in clinical practice. Efficacy, according to statistics, cervicitis accounts for about 40-50% of the total number of obstetrics and gynecology outpatients, ranking first in gynecological diseases. Therefore, it is of universal significance to strengthen the in-depth development of Guangdong Zizhu. Guangdong Zizhu is the dry stem, branch and leaf of the Verbenaceae plant Guangdong Zizhu (Callicarpa kwangtungensis Chun.). It is mainly produced in Pingxiang, Anyi, Yichun, Anyuan, Jinggangshan, Anfu and other ...
