“…Yet, only for six species i.e., A. atropurpurea [ 8 , 9 ], A. australis [ 8 , 9 ], A. macrophylla [ 8 , 16 , 17 , 18 , 19 ], A. microstachya [ 8 , 20 ], A. ovata [ 8 , 9 ] and A. robusta [ 8 , 9 , 22 , 23 , 24 , 25 ], the phytochemical studies regarded both kinds of natural compounds. Indeed, for four species i.e., A. borneensis [ 11 ], A. dammara [ 12 ], A. moorei [ 8 ], and A. philippinensis [ 21 ], only the essential oil composition was studied whereas for two species i.e., A. alba [ 6 , 7 ] and A. lanceolata [ 14 , 15 ], only the polar fraction composition was analyzed. Among the essential oil metabolites, none has been reported in all the compositions present in literature.…”
