Buske, A.; Schmidt, J.; Hoffmann, P.; Chemotaxonomy of the tribe Antidesmeae (Euphorbiaceae): antidesmone and related compounds Phytochemistry 60, 489-496, (2002) DOI: 10.1016/S0031-9422(02)00117-6
Selected species of the tribe Antidesmeae (Euphorbiaceae, subfamily Phyllanthoideae) have been screened for antidesmone occurrence and its content by quantitative HPLC (UV) and qualitative LC–MS/MS analysis. The LC–MS analysis allowing the additional detection of 17,18-bis-nor-antidesmone, 18-nor-antidesmone, 8-dihydroantidesmone and 8-deoxoantidesmone was carried out in the selected reaction monitoring (SRM) mode. Leaf material from herbarium specimens of 13 Antidesma spp., Hyeronima alchorneoides and Thecacoris stenopetala (all subtribe Antidesminae), as well as Maesobotrya barteri, Aporosa octandra (both Scepinae) and Uapaca robynsii (Uapacinae) were analysed. Additionally, freshly collected samples of different plant parts of two Antidesma spp. were investigated to ensure the significance of the results on herbarium specimens and to compare the antidesmone content in bark, root and leaves. Antidesmone could be unambiguously identified in 12 of 13 Antidesma spp., as well as in the two other investigated genera of subtribe Antidesminae, in levels of up to 65 mg/kg plant dry weight. Antidesmone was not found in specimens from other subtribes. Antidesmone-derived compounds occur in much lower concentrations than antidesmone.Selected species of the tribe Antidesmeae (Euphorbiaceae, subfamily Phyllanthoideae) have been screened for the occurrence of antidesmone and some derived compounds by HPLC and LC–MS/MS analysis, including selected reaction monitoring (SRM). Antidesmone could be identified in 12 of 13 Antidesma species as well as in the two other investigated genera of subtribe Antidesminae. It was not found in specimens from other subtribes.
