title: [Coumarins from Peucedanum harry-smithii var. subglabrum].
abstract: The root of Peucedanum harry-smithii var. subglabrum was extracted with methanol, then separated with solvents at different polarity into four fractions: aqueous (H2O), ethyl acetate (AcOEt), chloroform (CHCl3) and petroleum ether (DAB-6). From AcOEt psoralen, bargapten, xanthotoxin, marmesin, umbelliferone, scopoletin, (+/-) peuformosin, Pd-I b, (+/-) selinidin, praeruptorin D were isolated by column chromatography on silica gel, using petroleum ether/ethyl acetate as eluent. The structures of the coumarins were identified by 1H-NMR and 13C-NMR.
