Chemical structures of antifungal compounds isolated from plants. In structures 3–7, R, R1 & R2 stands for the following substituents. (3). R = β-d-glucopyranosyl-(1→3)-α-l-rhamnopyranosyl-(1→2)-α-l-rhamnopyranosyl-(1→2)-α-l-arabinopyranoside. (4). R1 = α-l-rhamnopyranosyl, R2 = H. (5). R = β-d-glucopyranosyl-(1→3)-α-l-rhamnopyranosyl-(1→2)-α-l-arabinopyranoside. (6). R = α-l-rhamnopyranosyl-(1→2)-α-l-arabinopyranoside. (7). R1 = α-l-arabinopyranosyl, R2 = β-d-glucopyranosyl
