Plant Toxicity and Pharmacological Properties

The leaves of Buxus sempervirens L. contain sitosterol, stigmasterol, cycloartenol, lupeol, germanicol and β-amyrin in the free state. All of these compounds, except stigmasterol, were also found in the esters fraction, as were obtusifoliol, 24-methylenelophenol, and 24-ethylidenelophenol, The triterpene diois betulin and moradiol were isolated, the latter for the first time from a plant source. In nineteen Buxus samples from England, Wales and Scotland, the sterol compositions were quite similar while those of the triterpene monols varied considerably.
