Scrophularia peyronii Post. from Jordan: Chemical Composition of Essential Oil and Phytochemical Profiling of Crude Extracts and Their In Vitro Antioxidant Activity
Get PDFThe genus Scrophularia is one of the largest genera belonging to the Scrophulariaceae family. Different members of the genus exhibit an interesting, wide spectrum of bioactivities. Accordingly, the current study aimed to investigate, for the first time, the chemical composition of the essential oil of Scrophularia peyronii Post. from Jordan. Additionally, extracts obtained from the aerial parts with solvents of different polarities were assayed for their phytochemical constituents and in vitro antioxidant activities. The major constituents detected in the essential oil, as revealed by GC/MS analysis, contained mainly Z,Z-farnesyl acetone (11.04%), β-elemene (6.36%), n-octanal (5.98%), and spathulenol (4.58%). Each of the aqueous methanol (Sp-M) and butanol (Sp-B) extracts contained flavonoids, saponins, anthraquinone, and glycosides. Both extracts were evaluated for their total phenolic content (TPC), total flavonoid content (TFC), and their in vitro antioxidant activity, which were assayed using the DPPH radical scavenging activity and ABTS radical scavenging methods. Additionally, the two extracts were then subjected to LC-ESI-MS/MS for the qualitative determination of their secondary metabolite content, especially in flavonoids and phenolic compounds. The results showed that the Sp-B extract of S. peyronii had the highest contents of both phenolic compounds and flavonoids and showed high radical scavenging activity, as determined by the two assay methods, when compared with the Sp-M extract. The LC-ESI-MS/MS analysis resulted in the detection of 21 compounds, including 8 flavonoids, 6 phenolic acids, 6 iridoids, and 2 acids. Although the majority of compounds were detected in both extracts, it was noticed that scropolioside B, 6′-O-cinnamoylharpagide, isoferulic acid, and 6-O-methylcatapol were only detected in the Sp-M fraction
Traditional Wild Food Plants Gathered by Ethnic Groups Living in Semi-Arid Region of Punjab, Pakistan
Get PDFWild edible food plants (WFPs) are valuable resources in the traditional food systems of many local cultures worldwide, particularly in underdeveloped regions. Understanding patterns of food preferences requires conducting cross-cultural food studies among various ethnic groups in a specific area. In this context, the current study aimed to record WFP use among five ethnic groups in Punjab, Pakistan, by interviewing 175 informants selected through snowball sampling. The indicator food species for different ethnic groups were calculated using indicator analysis based on the percentage of citations. A total of 71 wild food plants (WFPs) belonging to 57 genera and 27 families were observed in the study area. A high proportion of these wild food plants (WFPs) belonged to Fabaceae with eleven species (15%), followed by Moraceae with seven species (9%). Fruits were most widely used (43%), followed by leaves (19%), and shoots (16%). The majority (35 species, 49%) of plants of WFPs were eaten as cooked vegetables. A cross-cultural comparison revealed that four species overlapped among five ethnic groups (Arain, Jutt, Rajpot, Mewati, and Dogar). The Arain ethnic group gathered and consumed a remarkable number of wild plants (35 species), possibly due to a special connection with the general abundance of the local flora, and being close to nature by adopting professions more allied to WFPs in the study area. The analysis of indicator species revealed distinct significant indicator values (p ≤ 0.05) between the main food species among the various ethnic groups. Amaranthus viridis was a common indicator of food in all five ethnic groups, while Ziziphus nammularia was a common indicator food plant of the Mewati, Rajpot, and Jutt ethnic groups; these plants are important in local diets, especially during times of food scarcity brought on by disease or drought. In addition, the current study reports 20 WFPs that have been rarely documented as human food in Pakistan’s ethnobotanical literature. Future development plans should consider biocultural heritage and pay appropriate attention to local ecological knowledge, dynamics, and historical exchanges of traditional food systems
