Myricetin-3-O-rutinoside

Licania apetala var. apetala (E. May) Fritsch is a tree native to the Amazonian forest. Its leaves were extracted with the same method used for L. licaniaeflora. From the n-butanol extract of the leaves seven flavonoids were obtained quercetin 3-0- 3-D-galactopyranoside (6), quercetin 3-O-a-L-rhamnopyranoside (8) quercetin 3-O-rutinoside (18), quercetin 3-0-a-L-arabinopyranoside (9), taxifolin 3-O-a-L-rhamnopyranoside (64), myricetin 4 -O-a-L-rhamnopyranoside (66), and kaempferol 3-O-rutinoside (67), [see Fig. (1), (2), (7), and (8)] [18].
