Mineral and essential oil composition of jackfruit (Artocarpus heterophyllus) leaves

Abstract

The preliminary phytochemical contents of the leaves of Artocarpus heterophyllus were studied using standard methods, the mineral content of the leaves of A. heterophyllus was studied using Atomic absorption spectrophotometry (AAS) while the essential oil components were studied using GC-MS. The qualitative screening of the leaves for phytochemicals showed the presence of alkaloids, flavonoids, carbohydrate, terpenoids, tannins, cardiac glycoside, steroids, saponin, and carboxylic acid. The mineral analysis using Atomic absorption spectrophotometry (AAS) showed the presence of magnesium, potassium, calcium, sodium, phosphorus, zinc, copper, manganese, chromium and iron. The GC-MS analysis of the essential oil revealed eight different compounds; 1H-Indene, 3-methyl-, Neophytadiene, Hexadecanoic acid, methyl ester, Methyl 9-cis 11-trans-octadeca dienoate, 9,12,15-Octadecatrienoic acid, methyl ester, (Z,Z,Z)-, Phytol, Methyl stearate and Diisooctyl phthalate at a concentration of 2.128%, 1.321%, 27.160%, 11.267%, 30.587%, 19.867%, 5.006% and 2.665% respectively. This study shows that the leaves of A. heterophyllus are rich in bioactive components.
