چکیده
The new compounds 2-methyl-6-isopropyl-7-hydroxymethyl naphthalene (1), oxyphyllenone H (2), epi-oxyphyllenone (6), (E)-labda-12,14-dien-15(16)-olide-17-oic acid (3), and two new natural products 4 and 5 were isolated from the ethyl acetate part of 95% ethanol extract of Alpinia oxyphylla, together with six known compounds 7-12. The inhibitory effects of compounds 1-12 on α-glucosidase were evaluated, and compounds 1, 3 and 6 showed moderate bioactive effect, with inhibitory rates of 10.3%, 10.0% and 11.5%, respectively, compared to the positive control acarbose (41.9%) at 20 µg/mL.

Oxyphyllones A and B, novel sesquiterpenes with an unusual 4,5-secoeudesmane skeleton from Alpinia oxyphylla
Two novel 4,5-secoeudesmane sesquiterpenoids, oxyphyllones A (1) and B (2) were isolated from the fruits of Alpinia oxyphylla. Their structures were established by spectroscopic methods including 1D and 2D NMR spectra. These two compounds are the first example of naturally occurring sesquiterpenoids with a 4,5-secoeudesmane skeleton in the family of Zingiberaceae and oxyphyllone A (1) is the fi...
