- 論文の詳細を見る
Chemical constituents of the flower of Cammellia japonica, Theaceae were investigated. Three flavonols, quercetin, kaemferol and sexangularetin and three phenolic compounds, p-hydroxybenzoic acid, protocatechuic acid and gallic acid were identified. A sterol mixture of α-spinasterol and stigmast-7-en-3β-ol, and a glucoside mixture of stigmastry-D-glucoside and β-sitosteryl-D-glucoside were identified on the basis of spectral evidence and gas chromatography. A new triterpene, 3β-hydroxy-28-norolean-17-en-16-on-12,13-epoxide was also identified on the basis of chemical and spectral data.
