Aframomum stipulatum (Gagnep) K. Schum and Aframomum giganteum (Oliv. & Hanb) K. Schum as Aroma Tincto Oleo Crops resources: essential oil, fatty acids, sterols, tocopherols, and tocotrienols composition of different fruit parts of Congo varieties

Abstract

BACKGROUND: Today, few known plant species provide both an essential oil (EO) and a vegetable oil (VO). Seed and husk of two Aframomum species were investigated and compared in terms of EO, fatty acids, tocopherols, and tocotrienols. RESULTS: EO yield reaches 15.3 g kg−1 in the seeds and 3.2 g kg−1 in the husks, while VO yield is 180.0 g kg−1 in the seeds and 25.0 g kg−1 in the husks. β‐Pinene, 1,8‐cineol, α‐selinene, terpine‐4‐ol, linalool, myrtenal and β‐caryophyllene are the major compounds of seed and husk EO. Fatty acid analysis of two Aframomum species shows that oleic, linoleic, and palmitic acids were the major compounds of VO. Total sterol contents reached 4.3 g kg−1 in seed VO and 8.5 g kg−1 in husk VO. An appreciable amount of tocopherols (0.52 g kg−1) was found in seed VO. CONCLUSION: The seed and husk oil of A. stipulatum and A. giganteum fruits are rich sources of many bioactive constituents such as fatty acids, sterols, tocopherols and tocotrienols. These tropical wild fruits can be considered as new Aroma Tincto Oleo Crops (ATOC) resources that contain both EOs and VOs. Copyright © 2012 Society of Chemical Industry

Thermal Properties of Monoglycerides from Nephelium Lappaceum L. Oil, as a Natural Source of Saturated and Monounsaturated Fatty Acids

“…The oil extract was concentrated in a rotary evaporator by distillation at reduced pressure and 40 °C until the solvent was totally removed. Mean kernel content was determined gravimetrically using three different samples replicated three times. − …”

A review on chemical constituents of essential oils of Aframomum genus

“…For instance, the principal compounds of the leaf oil from Kinshasa region were thymol, eugenol and p-Cymene. The husk oil of this species possessed β-pinene, 1,8-cineol and α-terpineol as the major components while β-pinene, β-caryophyllene and α-humulene were the dominant compounds of the seed oil (Ngakegni et al, 2013). In addition, the essential oils of A. exscapum (Sims) Hepper collected from various locations of the Ivory Coast have been reported.…”

“…The composition of essential oils isolated from A. giganteum have been reported by previous studies. Accordingly, the seed essential oil of A. giganteum collected from the Congo Republic was characterized by the predominance of β-pinene, 1,8-cineol and α-selinene while the husk oil possessed α-selinene, linalool and β-pinene as the major components (Ngakegni et al, 2013). In addition, the leaf oil of A. giganteum grown in Gabon was found to be rich in cis-pinocamphone, cis-pinocamphone and trans-verbenol while caryophyllene oxide, β-caryophyllene and β-caryophylla-4(14),8(15)-dien-5-ol were the main compounds in the rhizome oil (Agnaniet et al, 2004).…”

Chemical Profile and Radical Scavenging Activity of Extracts <i>Musanga cecropioides</i> (R. Brown) Seeds Oil from Congo

“…Before analysis by gas chromatography (GC), triacylglycerols of vegetable oils and fatty acids (FAs) were transformed into their corresponding methyl esters (FAMEs) according to the procedure reported by Müller [12,13]. Twenty milligrams of oilwere solubilized in 1 mL TBME, and then 100 µL of this solution was mixed with 50 µL TMSH solution (0.5 mol.L -1 in methanol).…”
