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.

：被鉴定为蝶形青草蓝（Pseudozizeeria maha）寄主的Oxalis corniculata的叶子中的三个C-糖基黄酮被鉴定为6-C-葡萄糖基酪蛋白（isoorientin），6-C-葡萄糖基芹菜素（isovitexin）和异维新毒素7 -甲醚（swertisin）。寄主植物的叶提取物与P. maha的翅膀之间的比较光谱和HPLC分析表明，寄主植物的类黄酮异黄酮毒素对蝴蝶的翅膀有选择性的吸收。
