Abstract
In order to confirm the structures of momilactones A (3-oxo-9β-pirnara-7,15-dien-19,6p-olide)(I) and B (3,20-epoxy-3α-hydroxy-9β-pimara-7,15-dien-19,6β-olide)(XIII), growth-inhibitors isolated from husk of rice, their chemical and physical properties were studied in detail. Momilactone B gives a rearrangement product (XVII) on treatment with alkali, whereas momilactone A affords a decarboxylation product (X).This publication has 0 references indexed in Scilit:
