The overwintering eggs and the larvae of the leaf beetleGaleruca tanaceti (L.) contain hydroxylated anthraquinones. In both developmental stages, l,8-dihydroxy-3-methylanthraquinone (= chrysophanol) and 1,8-di-hydroxyanthraquinone (= chrysazin) were detected by GC-MS and GC-FTIR analyses. In the eggs, chrysazin was found only in traces. Anthraquinones were also present in ovaries and hemolymph of gravid females, which were investigated in order to examine the incorporation of these substances into the eggs. Neither in acidified nor in nonacidified extracts of the host plantsTanacetum vulgäre L. andAchillea millefolium L. were anthraquinones found. The activity of these anthraquinones as chemical defense substances was proved in bioassays with the antMyrmica ruginodis NYL. Further possible biological significances of anthraquinones are discussed.
越冬卵和叶甲幼虫（Galeruca tanaceti（L.））含有羟基蒽醌。在两个发育阶段，GC-MS 和 GC-FTIR 分析均检测到 1,8-二羟基-3-甲基蒽醌（=大黄酚）和 1,8-二羟基蒽醌（=大黄素）。在卵中，大黄素仅以微量存在。大黄素也存在于怀孕雌性的卵巢和血淋巴中，对其进行了研究，以检查这些物质是否被纳入卵中。在宿主植物Tanacetum vulgäre L.和Achillea millefolium L.的酸化和非酸化提取物中均未发现蒽醌。这些蒽醌作为化学防御物质的活性在与蚂蚁Myrmica ruginodis NYL 的生物测定中得到了证明。进一步讨论了蒽醌的其他可能生物学意义。
