Phytochemical Characterization of Extracts from Fagraea Fragrans and Juglans Regia by GC-MS Analysis

Abstract

Fagraea fragrans and Juglans regia have several therapeutic applications. The present study aimed to analyze the phytochemical compositions of a methanolic crude extract from the stem bark of F. fragrans and an oily liquid from a chloroform extract of seeds of J. regia. Approximately, 220 g of methanolic crude extract (yield = ca.  5%) was obtained from the stem bark of F. fragrans from hot-solvent extraction, and approximately, 45 g of chloroform oily liquid (yield = ca. 1.5%) was obtained from the seeds of J. regia by maceration technique. The phytochemical compositions of these two extracts were analyzed separately by injecting an aliquot of 1.0 μL solution of each extract prepared in hexane to a GC-MS instrument fitted with a DB-5 column of the dimension 50 m × 0.25 mm, i.d., 0.25 μm film thickness. The presence of fourteen components, including fragrant aldehydes and bioactive sterols, was identified in the methanolic crude extract and the presence of eight components, including fatty acids, fatty esters, and γ-tocopherol, was identified in the chloroform oily liquid. For the first time, we report the presence of γ-tocopherol (3.46%), n-hexanoic acid (1.26%), ethyl hexadecanoate (4.70%), ethyl oleate (6.59%), and a high content of ethyl linoleate (29.93%) in this chloroform oily liquid. From this study, we concluded that F. fragrans and J. regia have bioactive compounds of pharmaceutical importance. Therefore, these compounds can be extracted from these plants for therapeutic applications.
