Essential oils of the AmazonGuatteria andGuatteriopsis species

Abstract

The essential oils of Guatteria juruensis, G. microcalyx, G. poeppigiana and Guatteriopsis blepharophylla were obtained by hydrodistillation and analysed by GC and GC/MS. The main compounds found in the leaf oil of Guatteria juruensis were spathulenol (77.5%) and α α α α α-pinene (4.5%). The leaf oil of Guatteria microcalyx was dominated by caryophyllene oxide (44.2%), α α α α α-pinene (11.9%) and β β β β β-pinene (6.3%). The major constituents identified in the leaf oil of Guatteria poeppigiana were spathulenol (53.0%), kushinol (10.9%) and humulene epoxide II (5.7%). The main volatiles found in the leaf oil of Guatteriopsis blepharophylla were caryophyllene oxide (51.0%), humulene epoxide II (6.8%) and 14-hydroxy-9-epi-(E)-caryophyllene (4.1%). The spathulenol and caryophyllene oxide could be considered as chemotaxonomic markers due their common occurrence in Xylopia, Guatteria and Duguetia species.

Polyphyly of Polycarpon (Caryophyllaceae) inferred from DNA sequence data

“…The close affinity between the genera of the Guatteria group has been suggested by many authors after Fries (1939Fries ( , 1943Fries ( , 1959 on the basis of leaf anatomy ( van Setten & Koek-Noorman, 1986), flower anatomy (van Heusden, 1992), fruit and seed morphology (van Setten & KoekNoorman, 1992), unusual chromosome differentiation and cuticular folding patterns (Morawetz & Waha, 1985), a distinct pollen type (Walker, 1971;Morawetz & Waha, 1985), and oil composition analysis (Maia & al., 2005). This close affinity was corroborated in a phylogenetic study based on rbcL sequences (Bygrave, 2000).…”

Antimicrobial and antileishmanial activity of essential oil from the leaves of Annona foetida (Annonaceae)

“…[19][20][21][22] Among these identified components, the oxygenated sesquiterpene spathulenol is considered as a chemotaxonomic marker of species of Annonaceae, because it has been identified in several species of this family belonging to the genera Annona, Artabotrys, Cleistopholis, Desmos, Duguetia, Fusae, Goniothalamus, Guatteria, Guatteriopsis, Hexalobus, Melodorum, Pachypodanthium, Piptostigma, Uvaria and Xylopia. 12,[19][20][21][22] (E)-caryophyllene is frequently found in the species of Annona, and could be considered together with caryophyllene oxide as chemotaxonomic markers for this genus. 12,[19][20][21][22] …”

The Guatteria Group Disentangled: Sinking Guatteriopsis, Guatteriella, and Heteropetalum Into Guatteria

“…(Fig. 1) (Morawetz & Waha 1985), a distinct pollen type (Walker 1971;Morawetz & Waha 1985), oil composition analysis (Maia et al 2005), and wood anatomy ). These studies suggested a close affinity of the four genera but did not determine their phylogenetic relationships with respect to each other.…”
