[0015] The preparation of example 1Gigantol

[0016] The Gigantol extraction method is a prior art, and the inventor refers to the literature (Zhang Chaofeng, Shao Li, Wang Lei, etc. Research on the chemical constituents of Dendrobium dendrobii [J] Chinese Journal of Traditional Chinese Medicine, 2008, 33 (24): 2922~2925. Yang Li, Gu Lihua, Wang Zhengtao, et al. Qualitative and quantitative analysis of bibenzyl components in Dendrobium sheath [J] Chinese Journal of Pharmaceutical Sciences, 2007, 42(21): 1620-1623.) report on preparation of gigantol, specific implementation process as follows:

[0017] Dried Dendrobium nobile, chopped into coarse powder, heated and refluxed with 95% ethanol to extract 2 to 3 times, the amount of ethanol added each time was 12000ml / kg of medicinal material, refluxed for about 2 hours, combined with the medicinal liquid, suction filtered, and the filtrate was concentrated to There is no ethanol smell, and the extract is obtained, which is suspe...

Abstract

The invention relates to a medical preparation containing organic effective constituents, in particular to the application of a compound 3',4-dyhydroxyl-3,5'-dimethoxybibenzyl in preparing medicaments for treating cataract. The compound has double-target inhibition activity, and not only can inhibit the activity of AR to resist high osmotic pressure, but also can inhibit the activity of iNOS to resist oxidation, thus the compound has good effect on resisting the cataract. The compound has small molecules, thereby not only being easy to absorb by the organism, but also being capable of penetrating cell membranes without accumulation effect and toxic and side effects.

Description

technical field [0001] The invention relates to pharmaceutical preparations containing organic active ingredients, in particular to medicines containing bibenzyl compounds. Background technique [0002] Cataract is an eye disease with the highest morbidity and blindness rate in the world. There is no unified understanding of the pathogenic mechanism of cataract, but it is believed that cataract is closely related to lens protein degeneration. Treatments for cataracts include medication and surgery. Surgical treatment has certain risks. First, post-operative wound repair, residual lens epithelial cells (LEC) will rebound and proliferate and migrate, which will form cataract again, that is, "secondary cataract". More and more cataract patients belong to the early stage of development. Or waiting for surgery or the category of unsuccessful surgery; second, some elderly patients are often accompanied by other diseases such as diabetes, hypertension, heart disease, etc. Expens...
