Chemical constituents from Peucedanum decursivum / 中草药

ABSTRACT

Objective: To investigate the chemical constituents from Peucedanum decursivum. Methods: P. decursivum was extracted with 95% ethanol, the compounds were isolated via various chromatographic methods, and their structures were identified by detailed spectroscopic analyses. Results: Twelve compounds were isolated from the acetic ether fraction in the 95% extract of P. decursivum and were identified as isobergapten (1), bergapten (2), pimpinellin (3), isopimpinellin (4), columbianetin acetate (5), sphondin (6), qianhucoumarin E (7), xanthotoxin (8), osthole (9), ferulic acid (10), β-sitosterol (11), and psoralen (12). Conclusion: Compounds 1, 4, and 5 are isolated from the plants in Peucedanum L. for the first time, and compounds 2, 3, 6-10, and 12 are firstly isolated from P. decursivum.
