From the fruits of Ocotea minarum a new indole alkaloid, tryptophol-5-O-beta-D-glucopyranoside, was isolated in addition to the coumarin scopoletin and the flavonoids taxifolin, quercetin-7-O-beta-D-glucopyranoside, eriodictyol-3'-O-beta-D-glucopyranoside and naringenin-7-O-beta-D-glucopyranoside. A new alkyl phenol, 3-(1,4-dihydroxypentyl)-5-methoxyphenol, was obtained from the heartwood in addition to 5-propylresorcinol, trans-asarone, lyonyresinol, 3-O-beta-D-glucopyranosyl stigmasterol and stigmasta-4,22-dien-3-one, whereas from the trunk bark the sesquiterpene lanceolic acid (as its methyl ester derivative after methylation procedures) and beta-sitosterol were isolated. 5-propylresorcinol and lanceolic acid are reported for the first time as natural products.
