The mass spectra of 55 sesquiterpenoids containing 14 novel compounds were measured by gas chromatography-mass spectrometer (EI method at 70 eV), in which 15, 11, 10, 10, 4 and 5 compounds were classified such as longifolanes, caryophyllanes, cadinanes, cedranes, longipinanes and thujopsanes, respectively. Their spectra were studied systematically upon the relation of sesquiterpene skeleton and characteristic peaks of each skeleton were researched.On the result, common ions of m/z 109, 121, 135 and 161 were found in the mass spectra of longifolanes; common ions of m/z 119, 133, 161 and 177 were done in the mass spectra of caryophyllanes; common ions of m/z 121, 133, 147 and 161 were done in the mass spectra of cadinanes; common ions of m/z 95, 107, 135 and 147 were done in the mass spectra of cedranes; common ions of m/z 119, 133, 134 and 135 were done in the mass spectra of longipinanes and common ions of m/z 107, 121, 135 and 147 were done in the mass spectra of thujopsanes.
