A new dihydropyranocoumarin, (−)-6-methoxy-
trans-khellactone, has been isolated from the stems of
Ticorea longiflora, in addition to the known coumarins, osthol,
O-methylcedrelopsin and braylin, the anthranilate alkaloids, skimmianine, γ-fagarine, dictamnine, evolitrine and 4-methoxy-
N-methyl-2-quinolone, and trimethoxyphloroglucinol. From the leaves, we have isolated the coumarin, braylin, the furoquinoline alkaloids, skimmianine, evolitrine and γ-fagarine, and the steroids, stigmasterol and β-sitosterol. The structures of the isolated compounds were elucidated on the basis of spectral data.
