Abstract
Two new steroids, 3α,17α,19,20-tetrahydroxy-4α-methylpregn-8-ene (1) and 3α,12α,17α,20-tetrahydroxy-4α-methylpregn-8-ene (2) and three new sesquiterpenoids, 12-hydroxy-α-cadinol (3), 3α,12-dihydroxy-δ-cadinol (4), and 3α,6α-dihydroxyspiroax-4-ene (5), have been isolated from cultures of the fungus Phellinus igniarius. Their structures were characterized based on extensive spectroscopic data. In preliminary in vitro assays, compounds 3 and 4 exhibited the vascular-activities against phenylephrine-induced vasoconstriction with the relaxing rates of 11.0 % and 7.0 % at 3 × 10-4 M, respectively.
