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.
Cytotoxic steroids from Polyporus umbellatus
Planta Med 2010 Oct;76(15):1755-8.PMID:20458671DOI:10.1055/s-0030-1249926.
The steroids ergone (1), (22E, 24R)-ergosta-7,22-dien-3β-ol (2), 5α,8α-epidioxy-(22E,24R) -ergosta-6,22-dien-3β-ol (3), ergosta-6,22-dien-3β,5α,6β-triol (4), and Polyporusterone B (5) were isolated from Polyporus umbellatus by bioassay-guided approach. They showed potent anticancer activity against HepG2 cells. Ergone displayed remarkable anticancer activity against HepG2, Hep-2, and Hela cancer cells, of which HepG2 cells were the most sensitive. Furthermore, the cytotoxic effects of ergone on normal human cells (HUVEC) were smaller than on cancer cells. The results showed that ergone had more selective cytotoxic activity against cancer cells than against normal cells.
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.
