Abstract
Leaves (108 samples) of six Santalum insulare (Santalaceae) varieties, i.e. raivavense, margaretae, marchionense, raiateense, alticola, and insulare from French Polynesia, have been investigated for their O- and C-glycosylflavone contents. Apigenin-7-O-neohesperidoside was found in low amounts in all varieties except in some samples of variety insulare, whereas luteolin-7-O-neohesperidoside was found in high amounts in alticola and insulare varieties (19.2 and 24.9%, respectively). Apigenin-8-C-β-D-glucopyranoside (vitexin) was found in all varieties with contents ≤ 4.3 %, and the content of apigenin-6-C-β-D-glucopyranoside (isovitexin) was highest in marchionense variety (12.5%). Luteolin-6-C-β-D-glucopyranoside (isoorientin) contributes to the differentiation of marchionense and alticola varieties (39.6 and 40.5%, respectively), whereas apigenin-6,8-di-C-β-D-glucopyranoside (vicenin-2) was found in high amounts in raivavense, margaretae, and raiateense varieties (56.2, 53.7 and 55.8% respectively), together with luteolin-6,8-di-C-β-D-glucopyranoside (lucenin-2) (12.4, 15.8 and 18.6% respectively).
