16-epi-silicine, an alkaloids of the ervatamine-type from Pandaca caducifolia

The structures of two ervatamine-type alkaloids previously isolated from Pandaca caducifolia are established as the known silicine and the new 16-epi-silicine after careful NMR analysis of the two compounds and their olefinic derivatives.
