Abstract
The solid-state cultured products of Antrodia camphorata as health foods has been blooming for the past few decades in Taiwan. In continuing our studies on the chemical constituents of the solid-state cultured products of this fungus, 6-methoxy-4-methyl-2,3-(methylenedioxy)phenol (1) and 4,4′-(ethane-1,2-diyl)bis(2,3,6-trimethoxyphenol)(2) together with 2,3,6-trimethoxy-4-methylphenol (3), 1(10→6)abeo-ergosta-5,7,9,22-tetraen-3α-ol (4), citreoanthrasteroid B (5) and dankasterones A (6) and B (7) were purified by a series of column chromatography. Their structures were elucidated by spectral data analysis. For bioactivity assay, compounds 4–7 showed significant cytotoxicity toward murine colorectal CT26 and human leukemia K562 cancer cell lines with IC50 values ranging from 6.7 to 15.3 µM and from 12.5 to 23.1 µM, respectively.
