Essential oil composition ofVitex agnus-castus-comparison of accessions and different plant organs

Abstract

Leaves, immature and mature fruits of seven different accessions of chaste tree (Vitex agnus-castus L., Verbenaceae), cultivated at one location, were analysed for their essential oil composition. The main compounds of the essential oil were 1,8-cineole, sabinene, a-pinene, b-phellandrene and a-terpinyl acetate, trans-b-farnesene and bicyclogermacrene. Although the same compounds were present in all plant organs, the leaves differed from the fruits in the concentrations of all compounds except a-terpinyl acetate and <epi-13>manoyl-oxide. The compositions of immature and mature fruits were equal. Two distinct chemotypes (an a-pinene chemotype and an a-terpinyl acetate chemotype) could be identified in Vitex agnus-castus. Both chemotypes occurred between as well within accessions. The differences between the accessions were based mainly on the occurrence of these chemotypes in accessions and the frequency of their occurrence within accessions.

Chemical composition and acaricidal activity of the essential oils from Vitex agnus-castus L. (Verbenaceae) and selected monoterpenes

“…α-Pinene is another monoterpene that has been found in significant amounts in samples collected in Brazil (8.9%) (Zoghbi et al 1999), Spain (16.4%) (Novak et al 2005), Montenegro (9.4%) (Stojkovic et al 2011), Nigeria (9.1%) (Hamid et al 2010) and Italy (7.6%) (Senatore et al 1996). However, α-pinene was only found in the leaves in the present study, accounting for ≤ 2.3% of the oil.…”

“…Terpenoids with a greater molecular weight, such as diterpenes, have been found in different parts of the plant at amounts ranging from 7.9 to 0.1% in samples collected in Spain (Novak et al 2005), Brazil (Zoghbi et al 1999 and Italy (Marongiu et al 2010, Galletti et al 1996, Senatore et al1996. The most common diterpene in V. agnus-castus is reported to be manool and its derivatives.…”

“…NEVES and CLAUDIO A.G. DA CAMARA Different parts of V. agnus-castus (leaves, fruit and flowers) contain essential oils, the chemical composition of which varies with the geographic origin. Previous investigations into the essential oils of this species collected in different regions of the world have found the major constituents to be 1,8-cineole, limonene, α-pinene, sabinene, α-terpineol, β-(E)-farnesene, α-terpenil acetate, β-caryophyllene and bicyclogermancrene (Erygita et al 2015, Novak et al 2005. Due to the diverse biological properties of these chemical constituents, species of the genus are a rich source of bioactive compounds.…”

Vitex ferrugineaSchumach. Et. Thonn. subsp.amboniensis(Gürke) Verdc.: glandular trichomes micromorphology, composition and antifungal activity of the essential oils

“…Germacrene D were not detected in the oils of these species or it only occurs in a very low quantity (0-0.35%).The oil composition of V. ferruginea subsp. amboniensis is also very distinct from V. agnus-castus, the most well studied species of the genus, which is characterized by high amounts of monoterpenes, particularly sabinene and 1,8-cineole (5)(6)(7)(8)(9).…”

“…In Africa the genus is represented by c. 87 species included in two subgenera, Vitex and Homskioldiopsis (4). Despite its pantropical distribution and traditional uses, the research on the phytochemical and biological activities in Vitex has covered only a few species easily accessible: the European and Asian V. agnus-castus (5)(6)(7)(8)(9)(10)(11)(12), the Asian V. negundo, V. pseudo-negundo, V. rotundifolia and V. trifolia (13)(14)(15)(16) and the African V. diversifolia, V. obovata subsp. obovata, V. obovata subsp.…”
