“…As a matter of fact, the chemistry of Diospyros gilletii and other Diospyros species has been studied and reported by several authors [14][15][16][17][18]. The research by Tameye [17], which detailed the extraction and isolation of pure compounds in various parts (leaves, stem bark, and twigs) of Diospyros gilletii, led to the identification of seven coumarins: 11-O-(E)-cinnamoylnorbergenin (1) (leaves), 4-O-p-hydroxybenzoylnorbergenin (2), 4-Ogalloylnorbergenin (3), norbergenin (4) (leaves, stem bark, and twigs), a per-acetylated derivative of 4-O-p-hydroxybenzoylnorbergenin (5), a per-allylated derivative of 4-O-phydroxybenzoylnorbergenin (6) (stem bark), and 11-O-p-hydroxybenzoylnorbergenin (7) (twigs) (Figure S1, Supplementary Materials); three pentacyclic triterpene acids: ursolic acid (8), ursolic acid 28-allyle (9) (leaves), and corosolic acid (10) (leaves and twigs); and five pentacyclic triterpenoids: lupeol (11) (leaves, stem bark, and twigs), betulin (12) (leaves and twigs), betulinic acid (13) (leaves and stem bark), oleanolic acid (14) (leaves), and rotundic acid (15) (twigs) (Figure S2, Supplementary Materials). Compounds 8, 10, 11, 13, and 14 were also identified in Diospyros fragrans by the same research group [18].…”
