“…Phytochemical examination of P. glandulosus revealed the presence of secondary metabolites such as alkaloids, flavonoids, saponins, terpenoids, steroids, tannins, and glucosides [ 28 – 31 ]. Further phytochemical studies isolated a methoxylated flavonoid derivative plectranmicin, a monoterpene derivative plectranmicinol, and seven known compounds (5-hydroxy-3,7,2′,4′-tetramethoxyflavone, 5,7-dihydroxy-3,2′,4′-trimethoxyflavone, 7-hydroxy-5,6,4′-trimethoxyflavonen, 3-epi-betulinic acid, 3 -O-β -D-glucopyranosyl stigmasterol, β -sitosterol, and 4-epi-fridelin) [ 32 ]. Nanmeni et al [ 33 ] isolated seventeen compounds form de ethanolic whole plant extract including the mixture of stigmasterol and β -sitosterol, oleanolic acid, pilloin, β -sitosterol 3- O - β -D-glucopyranoside, chrysoeriol, luteolin 7-methyl ether, 5-hydroxy-7,4′-dimethoxyflavone, mixture of maslinic acid and benthamic acid, 5,6-dihydroxy-7,3′,4′-trimethoxyflavone, ladanein, hederagenin, cylicodiscic acid, mixture of chrysoeriol 5- O - β -D-glucopyranoside and 7- O -methyl luteolin 5- O - β -D-glucopyranoside, and galuteolin.…”
