Isolation of cuminal from Xylopia aethiopica

Composition and Antioxidant Activity of the Essential Oils of Xylopia aethiopica (Dun) A. Rich. (Annonaceae) Leaves, Stem Bark, Root Bark, and Fresh and Dried Fruits, Growing in Ghana

“…Other identified compounds were β-phellandrene, (E)β-ocimene, and bisabolene (25). Cumine aldehyde has been identified in the fruit essential oil of X. aethiopica from Egypt (3) and from Nigeria (26) in contrast to our samples, where it is practically absent. Sabinene has been found in the fruit essential oil from Nigeria (25) and from the Republic of Benin (36.0%) (27), while in our samples it was detected only in traces.…”

Characterization of the Key Aroma Compounds in Dried Fruits of the West African Peppertree Xylopia aethiopica (Dunal) A. Rich (Annonaceae) Using Aroma Extract Dilution Analysis

“…A number of diterpenes have been identified in different parts of the tree (Ekong and Ogan, 1968;Faulkner et al, 1985;Rabunmi and Pieeru, 1992;Harrigan et al, 1994a), and also several bioactive compounds have been found in its fruit (Ekong et al, 1969;Boakye-Yiadom et al, 1977;Hasan et al, 1982;Sanni et al, 1990;Harrigan et al, 1994b;Rabunmi and Pieeru, 1992). Ogan (1971) and Ekundayo (1989) reported that the volatile fraction of the fruits mainly consists of mono-and sesquiterpenes, among which Rand β-pinene, myrcene, p-cymene, limonene, linalol, and 1,8-cineole were the most predominant. Additional compounds identified in the volatile oil of the fruit include β-phellandrene, (E)-β-ocimene, R-terpineol, bisabolene, and cuminal (Ogan, 1971).…”

Recently, sabinene and terpinen-4-ol were found in the volatile oil of Xylopia fruits of a Nigerian variety (Onayade-Sontan, 1991), and two novel sesquiterpenes, namely, elemol and guaiol, were identified in the essential oil of the fruits grown in the Republic of Benin (Ayedoun et al, 1996) as well as in Cameroon (Jirovetz et al, 1997).…”

Ethnopharmacological Importance of Xylopia aethiopica (DUNAL) A. RICH (Annonaceae) - A Review

“…Different studies conducted on these essential oils have shown the presence of a wide diversity of chemical compounds. In one of the early studies conducted, Ogan [49] identified for the first time, an aromatic aldehyde specifically, cuminal (p-isopropyl-benzaldehyde) as a component of the essential oils obtained from the fruits of Xylopia aethiopica. After almost a decade later, Karawya et al [50] also analysed the essential oil from the dried fruits of Xylopia aethiopica and the only aldehyde identified was cuminic aldehyde at a concentration of 6.5%, corroborating Ogan's work.…”
