Three C-glycosylflavones in the leaves of Oxalis corniculata, the host plant of the lycaenid
butterfly pale grass blue (Pseudozizeeria maha), were identified as 6-C-glucosylluteolin
(isoorientin), 6-C-glucosylapigenin (isovitexin) and isovitexin 7-methyl ether (swertisin).
Comparative spectral and HPLC analyses between the leaf extract of the host plants and the
wings of P. maha showed selective uptake of the host-plant flavonoid isovitexin to the wings
of the butterfly.
