New Sesquiterpenoids and a Diterpenoid from Alpinia oxyphylla
AbstractThe 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.
