Studies of the active substances in herbs used for hair treatment. II. Isolation of hair regrowth substances, acetosyringone and Polyporusterone A and B, from Polyporus umbellatus Fries
Biol Pharm Bull 1999 Nov;22(11):1189-92.PMID:10598026DOI:10.1248/bpb.22.1189.
Fractionation of the 50% ethanol extract of Polyporus umbellatus Fries by column chromatography on Amberlite XAD-2, silica gel, Sephadex LH-20 and octadecyl silica gel (ODS) (C18)) monitored by a hair-regrowth activity assay, afforded three active principles, 1, 2 and 3. The structures of 1, 2 and 3 were determined as acetosyringone, Polyporusterone A, and polyporusterone B by comparison of their spectral data with that of authentic samples, respectively. The effects of several compounds related to acetosyringone, 3,4-dihydroxybenzaldehyde or Polyporusterone A on hair regrowth were also investigated.
Armillaria mellea Symbiosis Drives Metabolomic and Transcriptomic Changes in Polyporus umbellatus Sclerotia
Front Microbiol 2022 Feb 3;12:792530.PMID:35185819DOI:10.3389/fmicb.2021.792530.
Sclerotia, the medicinal part of Polyporus umbellatus, play important roles in diuresis and renal protection, with steroids and polysaccharides as the main active ingredients. The sclerotia grow and develop only after symbiosis with Armillaria sp. In this study, a systematic metabolomics based on non-targeted UPLC-MS method was carried out between the infected part of the separated cavity wall of the sclerotia (QR) and the uninfected part (the control group, CK) to find and identify differential metabolites. The biosynthetic pathway of characteristic steroids in sclerotia of P. umbellatus was deduced and the content of ergosterol, Polyporusterone A and B in the QR and CK groups were detected with the High Performance Liquid Chromatography (HPLC). Furthermore, the expression patterns of putative genes associated with steroid biosynthesis pathway were also performed with quantitative real-time PCR. The results showed that a total of 258 metabolites originated from fungi with the fragmentation score more than 45 and high resolution mass were identified, based on UPLC-MS metabolomic analysis, and there were 118 differentially expressed metabolites (DEMs) between both groups. The metabolic pathways indicated that steroids, fatty acid and carbohydrate were active and enriched during P. umbellatus sclerotia infected by A. mellea. The content of ergosterol, Polyporusterone A and B in the QR group increased by 32.2, 75.0, and 20.0%, in comparison to that of the control group. The qRT-PCR analysis showed that series of enzymes including C-8 sterol isomerase (ERG2), sterol C-24 methyltransferase (ERG6) and sterol 22-desaturase (ERG5), which played important roles in the final steps of ergosterol biosynthesis, all presented up-regulated patterns in the QR group in P. umbellatus. The comprehensive metabolomic and transcriptomic information will contribute to further study concerning the mechanisms of P. umbellatus sclerotial formation infected by A. mellea in the future.
Studies on constituents of fruit body of Polyporus umbellatus and their cytotoxic activity
Chem Pharm Bull (Tokyo) 1992 Jan;40(1):143-7.PMID:1576664DOI:10.1248/cpb.40.143.
From the crude drug Chorei, the fruit body of Polyporus umbellatus, seven new components named Polyporusterone A, B, C, D, E, F and G, were isolated and their structures were determined on the basis of the spectral data. These compounds showed cytotoxic action on leukemia 1210 cell proliferation.
Inhibitory effects of triterpenes isolated from Chuling (Polyporus umbellatus Fries) on free radical-induced lysis of red blood cells
Biol Pharm Bull 2005 May;28(5):817-21.PMID:15863885DOI:10.1248/bpb.28.817.
Chuling, sclerotia of Polyporus umbellatus FRIES, has long been used for urological disorders in traditional medicine. In this study, we demonstrated that Chuling in vitro protects red blood cells from 2,2-azo-bis(2-amidinopropane)dihydrochloride (AAPH)-induced hemolysis. The inhibitory effect was dose-dependent at concentrations of 50 to 1000 microg/ml. Moreover, tests were carried out to identify the main ingredient of Chuling with scavenging effect on free radicals. Triterpene carboxylic acids isolated from the methanol extract of Chuling, namely, Polyporusterone A and polyporusterone B, were found to have inhibitory activities against AAPH-induced lysis of red blood cells. The anti-hemolytic effect was significantly stronger in polyporusterone B compared with Polyporusterone A. Furthermore, the ingestion of 150 mg of Chuling was associated with a significant increase in free-radical scavenging effect of plasma in rats.
