A chemical survey of 49 Moroccan medicinal plant species comprising 45genera of 27 families was performed by electron spin resonance spectroscopy(ESR). 3,4-Dihydroxyphenylethanoid glycosides were especially evident as strongchemotaxonomic markers for the subfamily Lamioideae of the Lamiaceae, beingobserved in Marrubium vulgare, Aloysia triphylla and possiblyrecorded here for the first time in Oxyris quadripartita (Santalaceae).Chlorogenic acid was observed in Artemisia herba-alba but not in A. absinthium or in two other Asteraceae species. Rosmarinic acid wasobserved in Mentha spicata, Nepeta apulaei, Nepetasp., Thymus maroccanus and T. saturoides, all belongingto subfamily Nepetoideae of Lamiaceae. However, the acid was not observedin four other species of the subfamily. Thymoquinol was observed in Curcubitapepo, Crotalaria saharae, Nigella sativa (seed) and Piper longum but not in P. Cubeba. The compound was also foundin Thymus maroccanus but not in T. saturoides. A strongsignal of lawsone was observed with Lawsonia inermis. A naphthohydroquinoneof unknown structure as well as juglone were observed from the stem bark of Juglans regia. Protocatechuic and caffeic acids were observed in theseeds of Ricinus communis, Aloysia triphylla and in Nepeta sp. Gallic acid and/or its esters were observed in six speciesof six families and often observed together, e.g., in the leaves of Euphorbiafalcata. 6-Hydroxydopamine was identified in Piper longum. NoESR detectable phenolics were observed in nearly 20 species. [ABSTRACT FROM AUTHOR] |
