title: [Investigation on the chromatogram of diterpenoids in Pteris semipinnata by HPLC-APCI-MS].
abstract: To identify and compare the main peaks of HPLC-APCI-MS FP of the diterpenoids in Pteris semipinnata collected from different region and time, a quadrupole mass spectrometer coupled with atmospheric pressure chemical ionization interface was employed as a detector for HPLC to establish total ion chromatography. HPLC retention time and MS spectrum were used to identify comprehensively. 4F, 5F and 6F were identified from the chromatography comparing with their standards. The saturated state of 6F and glycoside of 4F and 5F were inferred. The content of 5F in samples collected from region of Guangzhou or in Nov. and Dec. were comparatively higher. This method is highly effective and fast,which can be applied to research and develop for diterpenoids in Pteris semipinnata L as new antitumor drug resource.
