- 中文摘要: 4.alpha.-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 clinically active components found in Antrodia cinnamomea. Using the specific fragmentation in their mass spectra together with the ratio of these diagnostic ions in their respective SIM mass spectra, and/or their MS/MS spectra, a fast, simple, and efficient mass spectral method has been developed for identification of these compounds in Antrodia cinnamomea preparations without prior isolation of the individual compound.
