Abstract
4 ha-Methylergosta-8,24(28)-dien-3,7,11-trion-26-oic acid and 4 alpha- methylergosta-8,24(28)-dien-3,11-dion-7 beta-ol-26-oic acid are two cl inically active components found in Antrodia cinnamomea. Using the spe cific fragmentation in their mass spectra together with the ratio of t hese diagnostic ions in their respective SIM mass spectra, and/or thei r MS/MS spectra, a fast, simple, and efficient mass spectral method ha s been developed for identification of these compounds in Antrodia cin namomea preparations without prior isolation of the individual compoun d.
