“…Melilotus species are rich in alkaloids, flavonoids, coumarins, triterpenes and saponins 5 . GC–MS Analysis of n -hexane extract of M. officinalis seed oil revealed the presence of coumarin (hepatotoxic compound) at significant level (8.40%), not recommending its oil utilization for cooking 13 .…”

Exploring novel sources of plant protein for nutrition of both humans and animals is motivated mainly by its growing demand worldwide, besides identifying healthy alternatives for animal protein. The present study evaluates metabolome diversity within 15 legume seed species. The examined samples comprised three Melilotus, four Medicago, four Trifolium, and four Ononis seed species. A holistic approach for metabolites profiling using gas chromatography-mass spectrometry (GC–MS) led to the annotation and quantification of 87 metabolites comprising alcohols, free amino acids, aromatics, fatty acids/esters, nitrogenous compounds, organic acids, sugar alcohols, sugars, terpenes, and steroids. Fatty acids represented the major metabolite class represented by palmitic, stearic, oleic, linoleic, and linolenic acids. Sucrose and pinitol were the major sugars and sugar alcohols among seeds. Ononis seeds (OR, OS and OA) were the most abundant in fatty acids, sugars, sugar alcohols, and free amino acids, whereas Melilotus species (MO and MS) were least enriched in these key nutrients posing Ononis as potential food source for humans and animals. The examined seeds were generally low in sulfur-containing free amino acids and lacking many of the essential free amino acids. Multivariate data analysis aided in the identification of Ononis metabolite markers belonging to various classes i.e., (alcohol) glycerol, (sugar) allofuranose, and (sugar alcohol) pinitol, although the differentiation between Medicago, Melilotus, and Trifolium genera was not attained suggestive for other analytical platforms for its classification.

Coriander (Coriandrum sativum L.) seeds are used as spices. In this study, fatty acids extracted from the coriander seeds collected from three places (Sululta, Jimma and Wolaita Sodo) in Ethiopia were determined as their methyl ester using GC-MS. The fatty acid components were assessed using linoleic acid ethyl ester as an external standard. Sululta sample showed five fatty acids, while Wolaita Sodo and Jimma three each with highest amount of petroselinic acid: 68.41%, 72.53%, and 64.4%, respectively, of the total fatty acids. Linoleic acid (omega-6) was found in the range of 18.24-22.37%. The polyunsaturated versus saturated (P/S) index values were found to be 1.69-2.39, which indicated that coriander seeds from the three sites have a good capacity to prevent the development of cardiovascular and some chronic diseases. The number of compounds identified in the essential oils of coriander seeds from Jimma, Sululta, and Wolaita Sodo were 7, 9, and 15 with total percent areas of 99.64, 75.14, and 96.68, respectively. The major component in the essential oils was linalool ranging from 36.72-88.50% of the total amount. In general, the chemical constituents of fatty acids and essential oils of coriander seeds indicates its good nutritional quality and usefulness for human health.
