Embodiment 1

[0027] Use 150kg of white poria cocos powder, soak in ether three times, each time for 48 hours, filter, take the cold extract, recover the ether under reduced pressure to obtain a light yellow extract (150g), pass through Si-gel C.C.CHCl 3 : MeOH (50:1-20:1) treatment, Fr.1, Fr.2, Fr.3 (20g), Fr.4 and Fr.5, five substances were obtained, Fr.3 (20g) was taken again Si-gel C.C.CHCl 3 :MeOH (50:1) treatment, get Fr.3.1, Fr.3.2 (15g) and Fr.3.3 three substances, take Fr.3.2 (15g) and give ODS C.C.MeOH:H 2 0 (85:15) treatment, Fr.3.2.1, Fr.3.2.2, Fr.3.2.3 (8g) Fr.3.2.4 and Fr.3.2.5 five substances, take Fr.3.2.3 (8g) Repeated recrystallization of methanol, compound pachynic acid-white crystals (1500mg). Mix it with olive oil to form a mixture with a concentration of 100mg / ml, sterilize it, and seal it to make a product.

Embodiment 2

[0029] The compound pachynic acid-white crystal obtained in Example 1 was mixed with olive oil to form a mixture with a concentration of 10 mg / ml, sterilized, and sealed to make a product.

Embodiment 3

[0031] Compound pachymic acid-white crystal 200mg obtained in Example 1 is made into capsules according to a known method to become a product.

Abstract

The invention relates to an application of a compound pachymic acid in the field of pharmacy. With the product, rejection reaction against transplant after transplant operation can be reduced, peripheral blood lymphocyte mitochondrial membrane potential stability can be protected; peripheral blood lymphocyte apoptosis percentage can be reduced, peripheral blood CD8+ lymphocyte number percentage can be stabilized, and so on. Under a non-transplant condition, peripheral blood lymphocyte percentage can be reduced, CD4+ and CD8+ lymphocyte number percentage can be regulated, and so on. When the compound is used for treating, transplant rejection reactions of transplantations of animal and human organ, tissue, cell, and the like can be reduced; and body lymphocyte number, proportion, and function can be regulated and stabilized.

Description

Technical field: [0001] The present invention relates to the application of the compound pachynic acid (3β acetoxyl 16α hydroxy lanoster 8,24(31) diene 21 acid), especially the application in the field of pharmacy. Background technique: [0002] The structural formula of the compound pachynic acid is [0003] [0004] The molecular formula of this compound is C 33 h 52 o 5 , white needle-like crystal, molecular weight 528, this compound can be prepared by extracting from the traditional Chinese medicine Poria cocos, and there is no application of this single compound in pharmaceuticals at present. Contents of the invention [0005] The purpose of the present invention is to provide a new application of the compound pachynic acid, that is, a new application in pharmacy. [0006] In fact, this project involves the application of compound pachymic acid as a medicine for treating or preventing rejection after transplantation. [0007] The invention relates to the appli...
