Problems solved by technology

[0017] Disclosed in CN 1322543 A is carried out ethanol extraction to the longan, and the method for purifying the longan amide alkaloid by saponification, the shortcoming of this method is: (1) used poisonous and carcinogenic solvent benzene in saponification, can cause production environmental pollution, can cause production workers poisoning, can bring toxic solvent residue, bring safety problem to product; The effect of the product will not be very good, and it is necessary to take a large amount of extracts, which is more likely to cause safety problems
The disadvantages are: (1) silica gel, alumina column chromatography and high pressure liquid chromatography are not easy to be industrialized; (2) there are environmental problems in using a large amount of silica gel and alumina; (3) the product cost is high; (4) it is difficult to obtain relatively Active parts of polyamide alkaloids

Abstract

The invention relates to a long pepper extract, a preparation method and a medicine combination thereof. The long pepper extract mainly contains methyl piperate and seven piperlongumine compounds, namely, peperlomguminine, piperine, decadiene amide, pepper nonine alkali, quinia, octadecyl triene amide and eicosatriene amide; by weight percentage, the total weight of the eight compounds accounts for 29.07-87.80 % of the total weight of the long pepper extract, wherein, peperlomguminine accounts for 0.95-3.43 % of the total weight of the long pepper extract, piperine accounts for 14.52-42.78 %,methyl piperate 0.82-3.11%, decadiene amide 1.36-4.27%, pepper nonine alkali 2.96-8.03%, quinia 1.04-3.26%, octadecyl triene amide 3.17-10.94% and eicosatriene amide 4.25-12.42%. The invention also provides the preparation method of the long pepper extract, the medicine combination and the application thereof.

Description

technical field [0001] The invention relates to a Piper longum extract, a preparation method thereof, a pharmaceutical composition containing the Piper longum extract and applications thereof. Background technique [0002] Piper Longum (Piper Longum L.) is the near-ripe or mature fruit of Piper Longum L. The fruit is harvested when it turns from green to black, removed from impurities, and dried in the sun. [0003] The functions and indications of Piper longum are warming the middle and dispelling cold, lowering Qi and relieving pain. For cold pain in the abdomen, vomiting, diarrhea, migraine; external treatment of toothache. [0004] The chemical components in Piper longum mainly include amide alkaloids, volatile oils, acids, esters, lignans and other components. Among them, the main active ingredients that have been studied in depth are amide alkaloids, methyl piperonate and volatile oils. Among them, amide alkaloids mainly play a role in reducing blood lipids, cardiov...
