Notes:
The mass spectra of three groups of tanshinones have been examined and a number of characteristic features noted which might be helpful in the micro-identification of the natural products. The fragmentation patterns are similar to each other except for the relative intensity within the same group of tanshinones and are accounted for in terms of the general fragmentations of furans and quinones. Characteristic ions at m/e 178, 165 and 152 found in all kinds of tanshinones may be considered to be of highly aromatized hydrocarbon fragments and are of good for the structure elucidation of these compounds.
