Abstract

The invention discloses a total alkaloids extractive of piper hancei and application thereof, belongs to the technical field of medicine, and in particular relates to a total alkaloids extractive of traditional Chinese medicine piper hancei and application thereof. The extractive is obtained from the traditional Chinese medicine piper hancei, and comprises the following alkaloid components: sinoacutine amide, hairy grama piperine, long pepper amide A, pepper a-amanitine, Guinea pepper, piperine, piperettine, piperovatine, N-p-tonka-bean acyl tyramine, N-trans- asafetida acyl tyramine, birthwort lactam AIIIa, birthwort lactam II, and 2E, 4E-N- isobutyl-7-3,4-methinedioxy phenyl-2, 4-diene heptamide, long pepper nerinine and a derivate thereof, wherein the total content of the total alkaloids components is counted by 5 to 100 percent by weight.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a total alkaloid extract of traditional Chinese medicine yam and its application. Background technique [0002] Betel is the stem, leaf or root of Piperaceae plant Betel, harvested in autumn, with pungent and warm nature. It has the effects of expelling wind and dampness, promoting blood circulation and reducing swelling, promoting qi and relieving pain, resolving phlegm and relieving cough. It is mainly used to treat wind-cold-damp arthralgia, stomach pain, dysmenorrhea, bruises, wind-cold cough and dyspnea, and hernia pain. Modern pharmacological studies have shown that betel can inhibit platelet aggregation induced by platelet activating factor (PAF), and inhibit the inflammatory response caused by PAF. Commonly used among the people to treat bruises, rheumatic arthralgia, etc. Betelwort mainly contains alkaloids, organic acids, sterols and glycosides, and so on...
