Myricetin-3-0-rutinoside from

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]. 

Figure 7.10 Separation of a standard mixture of 13 phenolic compounds by automated multiple development by use of a 20-step universal gradient composed of acetonitrile, methylene chloride, and hexane. The drying time was 4 min, and the gas phase for conditioning the plate between runs was prepared from 10% aqueous formic acid. The phenols were (1) rutin, (2) kaempf-erol-3-rutinoside, (3) quercetin-3-arabinoside, (4) quercetin-3-galactoside, (5) chlorogenic acid, (6) myricetin, (7) caffeic acid, (8) quercetin, (9) apigenin, (10) ferulic acid, (11) acacetin, (12) flavon, (13) coumarin.
