title: Alkaloids and coumarins of Thamnosma montana.
abstract: From the turpentine broom, Thamnosma montana, four alkaloids and three coumarins were isolated and characterized. Skimmianine (5), N-methyl-acridone (4) and 5-(3'-methyl-2',3'-dihydroxybutanyl)-8-methoxypsoralen (1) were obtained previously from T. montana. Robustine (2) is reported from a Thamnosma species for the first time and acridone (6), thamnosmonin (9), and thamontanin (14) are reported from a natural source for the first time. Evidence for the structures of the new isolates is presented.
