Terpenoids and coumarins isolated from the fruits of Poncirus trifoliata.
Four new triterpenes, 21alpha-methylmelianodiol (1), 21beta-methylmelianodiol (2), hispidol A 25-methyl ether (3) and hispidol B 25-methyl ether (4), and a new coumarin, isoschininallylol (5), were isolated from the fruits of Poncirus trifoliata RAFINESQUE, along with seventeen known compounds. The structures of the new compounds (1 - 5) were elucidated by interpretation of their spectroscopic data.
