Constituents of Some Essential Oil Bearing Plants from Nigeria

Abstract

The essential oils isolated from the air-dried leaves of four Nigerian plants of Commiphora kerstingii Engl (Burseraceae), Mangifera indica L., (Anacardiaceae), Callitris glauca R. Br. ex R.T. Baker. et H.G. Smith (Cupressaceae) and Ficus mucosa Welw. ex Ficalho (Moraceae), were analyzed for their constituents by GC and GC/MS. The volatile oil of Com. kerstingii contained (Z)-a-bisabolene (34.9%), b-bisabolene (9.3%), linalool (8.7%) and trans-a-bergamotene (7.9%) as the major constituents. On the other hand, the leaf oil of M. indica possessed a considerable proportion of a-gurjunene (23.6%), b-selinene (20.6%), b-caryophyllene (11.2%) and a-humulene (10.8%), while C. glauca had an abundance of a-pinene (19.6%) and limonene (13.1%). In addition, b-caryophyllene (37.0%), ethyl octanoate (14.9%) and methyl octanoate (8.3%) were the compounds occurring in higher percentages in the leaf oil of F. mucosa.

Essential oil Composition of Ficus Benjamina (Moraceae)and Irvingia Barteri (Irvingiaceae)

“…These compounds are conspicuously absent in the present study. Moreover, compounds such as phytol, 6, 10, 14-trimethyl-2-pentadecanone, and acorenone B, which are characteristics of other Ficus species from Nigeria [1][2][3]8], were not detected in the present investigation ( Table 2).…”

“…α-Copanene, cyclosativene and βocimene were the major compounds of its volatile oil [6]. The chemical composition of essential oils of some Ficus species growing in Nigeria have been reported [1][2][3][7][8][9][10]. Phytol and 6,10,14-trimethyl-2-pentadecanone have been described as chemical markers of Nigerian grown Ficus oils [2,3,[8][9][10].…”

Comparison of Microwave-Assisted and Conventional Hydrodistillation in the Extraction of Essential Oils from Mango (Mangifera indica L.) Flowers

“…The volatile constituents of mango have also been extensively investigated. In past decades, more than 300 volatile components have been identified from several varieties of mango [ 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ]. These compounds are free forms or glycosidically bound compounds [ 15 , 16 , 17 , 18 , 19 ].…”

Chemical Investigations of Essential Oils from Endemic Cupressaceae Trees from New Caledonia

“…C. rhomboidea stood out among these species because of the presence of large amounts of citronellyl-, neryl-and geranyl acetates. Several studies of the chemical composition of the leaf volatile oils from Callitris species introduced into Nigeria gave comparable results [17][18][19]. With the aim to clarify our first results on heartwood oils, the present paper reports, for the first time, the volatile components obtained by hydrodistillation of fresh leaves of C. neocaledonica, C. sulcata and N. pancheri from New Caledonia.…”
