Objective Analyzing the differences in fat-soluble chem. composition between cultivated and wild Lignosus rhinocerus. Methods The sclerotium of Lignosus rhinocerus was artificially cultivated, and then, the liposol. components were extracted from sclerotium by refluxing extraction with petroleum ether, and the difference in chem. compositions between cultivated (in rice and in sawdust, resp.) and wild Lignosus rhinocerus were analyzed by gas chromatog.-mass spectrometry (GC-MS). The relative percentages of components were also calculated Results Eleven, 10 and 14 compounds were identified from the ingredients in petroleum ether extracts of the rice group (RP), sawdust group (SP), and wild group (WP) resp. The majority of them are hydrocarbon compounds The common components are 2, 4-Di-tert-butylphenol, pentacosane and hentriacontane. The relative percentage contents of pentacosane and hentriacontane were 15.85%, 17.36%, 16.43% and 12.01%, 11.58%, 19.29% for RP, SP and WP, resp. The difference of these three are:the ingredients of the rice group mainly contain Ergosterol and Nonacosane; those of the sawdust group mainly contain Docosane, Tricosane, Tetracosane; those of wild group varieties mainly contain Tetracosane, Erucylamide, Di-Bu phthalate, and 9, 12-Octadecadienoic acid (Z, Z) -, Et ester. Conclusion The lipophilic composition in petroleum ether extracts of cultivated and wild Lignosus rhinocerus are identical, which included 2, 4-Di-tertbutylphenol, pentacosane and hentriacontane; but there are clear differences. These findings provide reference for the quality evaluation and utilization of cultivated products of Lignosus rhinocerus.2,2-Methylenebis(6-tert-butyl-p-cresol) (cas: 119-47-1) were involved in the experimental procedure.
HPLC of Formula: 119-47-12,2′-Methylenebis(4-methyl-6-tert-butylphenol)(CAS: 119-47-1) is a natural product found in Streptomyces and Aspergillus fumigatus .
