对马哈拟青霉的卵、幼虫、蛹和成虫中的黄酮类成分进行了鉴定和定量。在幼虫体内，异牡荆素(异牡荆素6-C-葡萄糖苷)和皂苷(异牡荆素-7-O-葡萄糖苷)是主要的黄酮类化合物。在幼虫的作用下，皂苷被异卵黄素生物转化为异卵黄素，在化蛹阶段被重新转化为异卵黄素。雌雄之间积累的总黄酮量不同，特别是在成虫体内，雌性体内的黄酮类浓度比雄性高得多。这些类黄酮类化合物也在鸡蛋中检测到。这些结果表明，黄酮类化合物不仅可能用于翅膀着色，还可能作为一种化学防御化合物来抵御自然威胁。
Flavonoids in the eggs, larvae, pupae and adult butterflies of Pseudozizeeria maha were identified and quantified. Isovitexin (apigenin 6‐C‐glucoside) was the dominant flavonoid detected in pupae and imagines, whereas saponarin (isovitexin 7‐O‐glucoside) was the dominant flavonoid in larvae. Saponarin, biotransformed from isovitexin by the larvae, was found to be reconverted into isovitexin at the pupal stages. The total amounts of accumulated flavonoids differed between sexes, particularly in adults where the bodies of females had a much higher flavonoid concentration than that of the males. These flavonoids were also detected in the eggs. These results indicate the possibility that flavonoids are utilized in not only wing coloration but also as a chemical defense compound against natural threats.
