Abstract

Two new compounds, (6__S__,13__S__)‐6‐{[β‐D‐glucopyranosyl‐(1→4)‐α‐L‐rhamnopyranosyl]oxy}cleroda‐3,14‐dien‐13‐ol (1) and kadsuric acid 3‐methyl ester (2), together with nine known compounds, (6__S__,13__E__)‐6‐{[β‐D‐glucopyranosyl‐(1→4)‐α‐L‐rhamnopyranosyl]oxy}cleroda‐3,13‐dien‐15‐ol (3), (6__S__,13__S__)‐6‐[6‐O‐acetyl‐β‐D‐glucopyranosyl‐(1→4)‐α‐L‐rhamnopyranosyl]oxy}‐13‐{[α‐L‐rhamnopyranosyl‐(1→4)‐β‐D‐fucopyranosyl]oxy}cleroda‐3,14‐diene (4), (6__S__,13__S__)‐6‐{[6‐O‐β‐D‐glucopyranosyl‐(1→4)‐α‐L‐rhamnopyranosyl]oxy}‐13‐{[α‐L‐rhamnopyranosyl‐(1→4)‐β‐D‐fucopyranosyl]oxy}cleroda‐3,14‐diene (5), 15‐hydroxydehydroabietic acid (6), 15‐hydroxylabd‐8(17)‐en‐19‐oic acid (7), junicedric acid (8), (4__β__)‐kaur‐16‐en‐18‐oic acid (9), (4__β__)‐16‐hydroxykauran‐18‐oic acid (10), and (4__β__,16__β__)‐16‐hydroxykauran‐18‐oic acid (11) were isolated from the fronds of Dicranopteris linearis or D. ampla. Their structures were established by extensive 1D‐ and 2D‐NMR spectroscopy. Compounds 1 and 3–8 showed no anti‐HIV activities.
