Abstract: A new 7,8-secolignan, as well as seven known compounds; were isolated from Nectandra turbacensis (Kunth) Nees (Lauraceae) (leaves and root bark). These compounds were identified as, one secolignan, turbacenlignan A (1); four diaryldimethylbutane lignans: meso-monomethyl dihydroguaiaretic acid (2), threo-dihydroguaiaretic acid (3), schineolignin B (4), and austrobailignan-5 (5);and three 7,7' -epoxylignans: henricine (6) and the identifiable mixture of veraguensin (7) and galgravin (8). Compounds 1-8, were first isolated from Nectandra turbacensis (Kunth) Nees (Lauraceae) (leaves and root bark) and compounds 1, 6-8, were isolated for the first time from Nectandra genus.
