Embodiment 1

[0019] 1. Extract the total flavonoids of lotus leaf and Tianjihuang: take 300 grams of lotus leaf and Tianjihuang medicinal materials, extract three times with 50-95% alcohol, concentrate the extract to 1 / 4-1 / 5 volume, and put it on D101 macropore Resin, eluted with water and 70% alcohol, collected the eluate, verified by magnesium powder / hydrochloric acid detection, collected the part with high flavonoid content, concentrated the eluate to dryness to obtain a solid, that is, the effective part product, weighed and determined the total flavonoids content.

[0020] Table 1 is the extraction yield and total flavonoid content of lotus leaf total flavonoids.

[0021] Table 2 is the extraction yield and total flavonoid content of Tianjihuang total flavonoids.

Abstract

The invention relates to a medicament complex which is prepared from total flavone extract of lotus leaf and hypericum japonicum thunb, and new usage for preparing anti-hepatitis B virus medicament. The total flavone of lotus leaf and hypericum japonicum thunb of the invention is total flavone extract which is separated and extracted from lotus leaf and hypericum japonicum thunb which grow in China. The complex of lotus leaf and hypericum japonicum thunb is separated and purified, tested by mass spectrum, 13C and 1HNMR, and proved to contain the following chemical components: quercetin, quercetin-3-O-beta-D-galactopyranose, isoquercetin, and kacmpferol and the like. The complex of total flavone extract is tested by in vitro cell model and in vivo animal model and proved to have strong activity of resisting hepatitis B virus and protecting liver. The complex of total flavone extract can be further prepared into anti-hepatitis B virus medicament and dosage forms can be capsules, tablets, granules, and injection and the like.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine, and relates to anti-hepatitis B virus drugs, in particular to a drug compound containing lotus leaf and tianjihuang total flavonoid extracts and its application in preparing anti-hepatitis B virus drugs. Background technique: [0002] The lotus leaf is the dry leaf of Nelumbo nucifera Gaertn., a plant of the water lily family, and is a food for both medicine and food. Lotus leaf is bitter, flat, returns liver, spleen, stomach meridian, is used for hot summer heat and polydipsia, summer-heat-damp diarrhea, diarrhea due to spleen deficiency, blood-heat vomiting at the nose, bloody stool and metrorrhagia. Studies have shown that lotus leaf is rich in a variety of active ingredients, such as: carotene, flavonoids, volatile oils, soaps, steroids, etc. Alkali and other alkaloids. The flavonoids rich in lotus leaf are scavengers of most oxygen free radicals, which can increase the activity...
