Plantes De Nouvelle-Caledonie. LXXVII. Diterpènes D'Agathis lanceolata

Antifeedant Activity of Anticopalic Acid Isolated from Vitex hemsleyi

“…This compound was previously isolated from Agathis lanceolata resin (Manh et al, 1983), Pinus strobus (Zinkel and Magee, 1987), and Trachylobium verrucosum resin (Hugel et al, 1996). The physical and spectroscopic data of 10 were consistent with those previously reported.…”

Phytochemistry, Chemotaxonomy, and Biological Activities of the Araucariaceae Family—A Review

“…Nevertheless, resin, stem barks, branches, and the generic aerial parts have also been considered. In some cases, one only type of organs were analyzed i.e., A. alba , A. australis , A. dammara , and A. ovata of which only the leaves were analyzed [ 6 , 7 , 8 , 9 , 12 , 13 ], A. lanceolata of which only the phytochemical analysis of the resin is reported in literature [ 14 , 15 ] and A. moorei of which only the phytochemical analysis of the leaves is reported in literature [ 8 ]. The exudate of only A. philippinensis [ 21 ] as well as the seeds of only A. robusta purchased in the United Kingdom [ 25 ] have been analyzed for their phytochemical composition reporting the presence of essential oil metabolites for the former and fatty acids for the latter.…”

“…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.…”

“…By the way, these compounds have actually been used as chemotaxonomic markers at the genus level [ 22 , 28 , 29 , 30 , 31 , 32 , 33 ], even if their occurrence seems, now, to be extended at the whole family level. Some diterpenes have also been reported for this genus from A. lanceolata [ 14 , 15 ], A. macrophylla from China [ 16 ] and from Fiji [ 18 , 19 ] and the resin of A. microstachya [ 20 ]. Only in one case i.e., A. macrophylla , some triterpenes have also been noticed [ 17 ].…”

“…In some cases i.e., A. atropurpurea leaves from Australia [ 8 ], A. australis leaves [ 8 ], A. macrophylla from Australia [ 8 ], A. microstachya leaves [ 8 ], A. moorei [ 8 ], A. ovata from Australia [ 8 ], and A. robusta from Australia [ 8 ], [α] D and NMR analyses accompanied the GC ones. Indeed, for the analysis of the polar fraction metabolites, SE was the only method for the extraction of these compounds, CC, TLC, LC, and HPLC, together or separated, were the methods for the separation procedure of the compounds and [α] D , IR, NMR, and MS, together or separated, were the methods for the identification procedure of the compounds [ 6 , 7 , 9 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 22 ].…”
