Abstract

The invention relates to a total flemingia philippinensis flavonoid extract and an extracting method and medicinal application thereof, and belongs to an extract in an active medicinal part of a Chinese medicament and an extracting method and medicinal application of the extract. The method comprises the following steps of: drying and crushing flemingia philippinensis serving as a Chinese medicament, performing reflux extraction, microwave aided extraction or ultrasonic aided extraction by using 40 to 85 percent ethanol, filtering, concentrating, drying to obtain a crude total flemingia philippinensis flavonoid extract, separating and purifying with AB-8 macroporous resin, collecting the eluent, recovering the solvent, and thus obtaining the total flemingia philippinensis flavonoid extract for new Chinese medicament research, wherein the total flavonoid content measured by adopting ultraviolet spectrophotometry is more than 50 percent. The purified total flemingia philippinensis flavonoid extract has the effects of treating diseases such as hyperlipidemia and thrombus.

Description

technical field [0001] The invention belongs to a preparation method of a traditional Chinese medicine extract and a medicinal use thereof, and in particular relates to an extract of total flavonoids from qianjinba, an extraction method thereof and a medicinal use thereof. Background technique [0002] Qianjinba belongs to the subfamily Papilionoideae of Leguminosac, and is widely distributed in the southeast, south-central, and southwest regions of China. The root of Qianjinba is used as medicine, which has the effect of dispelling rheumatism and strengthening the waist and knees. It is used for rheumatoid arthritis, lumbago and leg pain, lumbar muscle strain, leucorrhea, and bruises. "Dictionary of Chinese Medicine" records that "Qianjinba tastes sweet and pungent, slightly bitter, mild in nature, non-toxic, has the effects of dispelling wind and dampness, eliminating blood stasis and detoxification, and can treat rheumatic arthralgia, chronic nephritis, bruises, carbuncle...
