Biosynthesis of withanolides in Acnistus breviflorus: biogenetic relationships among the main withanolides

To excised leaves and 15-day-old seedlings of Acnistus breviflorus sodium [1-14C]acetate, [2-14C]mevalonolactone and [14C-methyl]methionine were administered in separate experiments. From the absolute incorporation values of withaferin A (1), jaborosalactone A (2) and jaborosalactone D (3) isolated...
