説明
The yellow hexane extract from Uroactinia hirschmanni HIRAMATSU (Acari: Mesostigmata) consisted of 2 compounds by GLC analysis, which gave the same molecular ion at m/z 188 with similar sets of fragment ions, and each of which was isolated by a preparative TLC. One was identified as plumbagin (5-hydroxy-2-methyl-1, 4-naphthoquinone) by GLC, GC/MS and NMR analyses using authentic compounds. The other was suggested to be its isomer from mass spectrum and was identified as 7-methyljuglone (5-hydroxy-7-methyl-1.4-naphthoquinone) by NMR spectrum. Glandular pores, responsible for emitting these naphthoquinones, were detected as black spots on the body surface, by dipping mites bodies in a Tollen's reagent (aqueous AgNO3-NH4OH). This study represents the first time these naphthoquinones have been demonstrated in such a time.
