RESUMO
OBJECTIVE: To observe the effects of Arbuscular Mycorrhizal (AM) fungi on terpenoids in Isodon adenantha. METHODS: Three different treated plant groups were divided as followings: indoor inoculation with AM fungi, non-inoculation with AM fungi, and outdoor natural growth, the effects of AM fungi on the major terpenoids in Isodon adenantha were evaluated. RESULTS: AM fungi had little influence on the content of terpenoids in underground part of Isodon adenantha, but they showed great impact on the content of terpenoids in the aerial part of the plant. CONCLUSION: The content of terpenoids in the aerial part of Isodon adenantha is positively correlated with AM fungi.

Seventeen compounds were isolated from the 95% ethanolic extract of the root of Ficus hirta. Their structures were identified on the basis of physicochemical properties and spectral data analysis. The structures were elucidated as cyclomorusin (1), 3-O-[(6-O-E-sinapoyl)-beta-D-glucopyranosyl]-(1 --> 2)-beta-D-glucopyranoside (2), 3,5,4'-trihydroxy-6,7,3'-trimethoxyflavone (3), quercetin (4), tricin (5), acacetin (6), luteolin (7), apigenin (8), (E) -suberenol (9), meranzin hydrate (10), methyl eugenol (11), 3-methoxy-4-hydroxybenzoic acid (12), p-hydroxybenzoic acid (13), methyl chlorogenate (14), emodin (15), alpha-amyrin acetate (16), and beta-sitosterol emodin (17), respectively. Compounds 1-6, 9-15 were isolated from this plant for the first time.
