We purified a sterol with antitumor activity from the edible mushroom Sarcodon aspratus (BERK.) S. ITO and identified it as 5alpha,8alpha-epidioxy-22E-ergosta-6,9(11),22-trien-3beta-ol (9,11-dehydroergosterol peroxide (9(11)-DHEP)). Purified 9(11)-DHEP was a more effective inhibitor of HL60 leukemia
Among the lipophilic extracts of seven traditional edible mushrooms, the acetone extract of Sarcodon aspratus markedly inhibited the growth of HL60 human leukemia cells and induced apoptosis after 24 h incubation. The major active component was identified as ergosterol peroxide by NMR and ESI-MS
Eleven compounds were isolated and purified from Phellinus igniarius by column chromatography on silica gel, Sephedax LH-20, RP-8, MCI and preparative TLC. Their structures were identified as 3α-hydroxyfriedel-2-one (1), 3-hydroxyfriedel-3-en-2-one (2), ergosta-4, 6, 8 (14), 22-tetraen-3-one (3),
Thirteen new sesquiterpenes, pulicanadiene A (1), B (2), and C (3), pulicanone (4), pulicanol (5), pulicanarals A (6), B (7), and C (8), pulicanadienals A (9) and B (10), pulicanadienol (11), and pulioplopanones A (12) and B (13), and seven known compounds, stigmasterol, ergosterol peroxide,
This study aims to identify bioactive anticancer and anti-trypanosome secondary metabolites from the fermentation culture of Aspergillus flocculus endophyte assisted by modern metabolomics technologies. The endophyte was isolated from the stem of the medicinal plant Markhamia platycalyx and
