Problems solved by technology

[0003] At present, due to the lack of antifungal compounds from natural sources, people have done a lot of work in the development of new drugs and the use of natural raw materials to extract new drugs, trying to find a strong antifungal effect and overcome the resistance of synthetic antibacterial drugs. However, among the many reports retrieved, there has been no report about papadin E (Plagiochin E)

Embodiment 1

[0027] The ground money (Marchantia polymorpa L.) collected from the area of ​​1000-1500 meters above sea level in Mount Emei, Sichuan Province was naturally dried and crushed to 8.95Kg, soaked in 8 times the volume of ground money in ether at 28°C for 5 days, filtered under normal pressure, collected ether and extracted Liquid I, repeated 4 times, combined extract I. Soak the medicinal dregs after the last extraction with 3 times the amount of methanol at 28°C for 4 times, each time for 3 days, filter under normal pressure, collect the methanol extracts, combine them, and concentrate under reduced pressure (vacuum degree 0.09Mpa) in a rotary evaporator at 60°C To obtain the methanol extract, extract the extract 3 times with ether equivalent to 3 times the amount of the extract, collect and combine the ether extract II, combine the two parts of the ether solution I and II, and then distill at 60°C to a fluid extract. Evaporate to dryness to obtain the total ether extract. Mix...

Embodiment 2

[0045] Naturally dry and crush Marchantia polymorpa L. collected from Emei Mountain, Sichuan Province, at an altitude of 1000-1500 meters to obtain 9.50Kg, soak in ether at 23°C for 4 days at 5 times the volume of Marchantia, filter under normal pressure, and collect ether for extraction. Solution I, repeated 6 times, combined extract I; soaked the medicinal dregs after the last extraction with 2 times the amount of methanol at 35°C for 5 times, each time for 2 days, filtered under normal pressure, collected methanol extracts, combined, and used a rotary evaporator Concentrate at 70°C under reduced pressure (vacuum degree 0.09Mpa) to obtain the methanol extract, extract the extract 4 times with ether equivalent to 2 times the amount of the extract, collect and combine the ether extract H, and combine the two parts of the ether solution I and II Afterwards, it was distilled at 70°C to a liquid extract, and evaporated to dryness naturally to obtain the total ether extract. Mix t...

Embodiment 3

[0047] Naturally dry and crush the picked Marchantia polymorpa L. to obtain 8.25Kg, soak 10 times the volume of Marchantia polymorpa in ether at 35°C for 7 days, filter under normal pressure, collect the ether extract I, repeat 3 times, and combine the extract I . Soak the medicinal dregs after the last extraction with 4 times the amount of methanol at room temperature for 3 times, each time for 2 days, filter under normal pressure, collect the methanol extracts, combine them, and concentrate on a rotary evaporator at 50°C under reduced pressure (vacuum degree 0.09Mpa) to obtain For the methanol extract, extract the extract twice with ether equivalent to 5 times the amount of the extract, collect and combine the ether extract II, combine the two parts of the ether solution I and II, and distill at 50°C to a liquid extract, and let it evaporate naturally. Dry to obtain the total ether extract. Mix the above-mentioned ether total extract with 3 times the amount of 300 mesh sili...

Abstract

A plagiochin E, its extracting and separating process, and its application in preparing antifunga medicines are disclosed.

Description

technical field [0001] The present invention relates to a bibenzyl compound and its extraction and separation method and application thereof, in particular to a bibenzyl compound pallagiochin E (Plagiochin E) and its extraction and separation method from Mossia genus Plantae and its application. Application in the preparation of antifungal drugs. Background technique [0002] Bibenzyl compounds are more common in bryophytes, structurally with C 6 -C 2 -C 6 The mother nucleus and its dimers exist, and are divided into different structural types based on the connection between the benzene rings, usually named according to the plant source; due to the different substituents of the benzene rings, many compounds are produced, named in turn according to the structural type they belong to. Such as dichantin B-H, J-L, phylloxin C, isophylloidin C, etc. (Susanne F., Ulrich HM., Brigirl DN., et al Biosynthesis of Cyclic Bisbibenzyls in Marchantia polymorpha. Phytochemistry, 2001, 5...
