Senyawa Flavonoid sangat popular ka

Senyawa Flavonoid sangat popular karena aktifitas antioksidannya, Beberapa senyawa yang telah dilaporkan pada genus Mikania yaitu bentuk kerangka flavon. Pada bagian aerial M.micrantha dan M. laevigata ditemukan Flavon glikosida 3,4',5,7-tetrahydroxy-6-methoxyflavone 3-O-β-D-glucopyranoside (66) (Ferreira & Oliveira, 2010; Huang et al.,2009). Spesies lain ditemukan senyawa flavone (67) pada M. hirsutissima (Ohkoshi et al.,1999). Pada M .micrantha berhasil telah diisolasi tiga senyawa flavon dari bagian aerial yaitu mikanin (68), alpinetin (69), mikanin-3-o-sulfate (sebagai garam K+) (70) (Jiang et al (2001). Dari bagian daun M. cordata telah diidentifikasi flavon sebagai mikanin-3-O-sulfate (sebagai garam Ca+2) (71), eupalitin-3-O-sulphate (sebagai garam K+) (72), eupalitin-3-O-β-D-glucoside (73), 6-methoxykaempherol-3-O-β-D-glucoside (74), nepetin (75) and kaempherol-3-O-α-L-rhamnoside (76) (Aguinaldo et al., 2003).

Flavonoid compounds are very popular due to the activities of antioksidannya, some compounds that have been reported in the genus Mikania that form the framework of flavon. On the aerial m. micrantha and m. laevigata found Flavon glycosides 3.4 '. 5 .7-tetrahydroxy-6-methoxyflavone 3-O-β-D-glucopyranoside (66) (Ferreira & Oliveira, 2010; Huang et al.,2009). Other species found flavone compounds (67) on m. hirsutissima (Ohkoshi et al. 1999). In m. micrantha successfully isolated three substances flavones from aerial parts of mikanin (68), alpinetin (69), mikanin-3-o-sulfate (as K + salt) (70) (Jiang et al (2001). From the leaves of m. cordata flavones were identified as mikanin-3-O-sulfate (as salts of Ca + 2) (71), eupalitin-3-O-sulphate (as K + salt) (72), eupalitin-3-O-β-D-glucoside (73), 6-methoxykaempherol-3-O-β-D-glucoside (74), nepetin (75) and kaempherol-3-O-α-L-rhamnoside (76) (Aguinaldo et al., 2003).
