The triterpenes ursolic acid (1), 27-p-Z-coumaroyloxyursolic acid (2), 27-p-E-coumaroyloxyursolic acid, alpha-amyrine-3-palmitate and lupeol-3-palmitate were isolated through a bioactivity-guided fractionation from the acetonic extract of the aerial parts of Viburnum jucundum Morton in addition to
The cytotoxic activity of two pentacyclic triterpenoids (ursolic acid and alpha-amyrine) isolated from the methanolic extract of the aerial parts from Erica andevalensis, whose structures have been established on the basis of spectroscopic and chemical evidence, has been assessed against three human
