[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...
