METHODS AND RESULTS:
Phytochemical investigation of the fruit of Schisandra chinensis led to the isolation of a schisanartane nortriterpenoid, schindilactone H (1); an 18-norschiartane bisnortriterpenoid, wuweizidilactone I (2); two tetrahydrofuran-type lignans, schinlignins A and B (18 and 19); and three dibenzyl butane-type lignans, schineolignin A，Schineolignin B,schineolignin C (20-22), together with 16 known compounds. The structures of these new compounds were elucidated on the basis of extensive analysis of spectroscopic data. | | Records of Natural Products, 2016,10(5):654-8. | | Lignoids Isolated from Nectandra turbacensis (Kunth) Nees (Lauraceae)[Reference: WebLink] |
METHODS AND RESULTS:
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).
CONCLUSIONS:
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. |
