Two rare megastigmane glucosides, 3- and 9-O-β-D-glucopyranosides of (3S, 5R, 6R, 7E, 9S) -megastigman-7-ene-3, 5, 6, 9-tetrol (1 and 2), were isolated from Hypericum erectum THUNB. Their structures were established on the basis of chemical and spectral data. This is the first report of the isolation of each megastigmane derivative from Guttiferae plant.

Doubt is often cast over the accuracy of the official statistics on crops, made public as FAOSTAT, for developing countries, particularly those in sub-Sahara Africa. This paper examines the recent revisions made in the ‘official’ rice statistics of Uganda, together with the rice-related statistics of the latest Uganda Census of Agriculture, to point out some anomalies in these basic rice statistics, and proposes possible revisions of the ‘official’ series.
