Chemical composition, antimicrobial and antioxidant properties of seed oil plants of North-East India: A review

Abstract

Apart from being used as food, seed oils have also been used traditionally as medicinal products by several communities. However, the full medicinal potential of many seed oil plants is yet to be properly reviewed, particularly for their antimicrobial and antioxidant properties. North-East India has rich resources of seed oil plants. The availability of detailed information on these plants is quite limited. This review aims to explore and evaluate these seed oil plants of the North-East India with particular emphasis on their antimicrobial and antioxidant activities as well as chemical compositions. A comprehensive literature search on seed oil plants of this region has been performed. Seed oil yielding plants of this region can be categorized into two categories: plants that are used traditionally as sources of edible or medicinal oils and plants that are used for purposes other than as sources of oils. Many seed oil plants of this region have been reported to possess antimicrobial and antioxidant properties, and to produce various types of compounds. This review also highlights the importance of these plants in contributing to the local as well as the national economy of India.

Comparative evaluation of physicochemical and antimicrobial properties of rubber seed oil from different regions of Bangladesh

“…seed oil was more effective on Gram (+) bacteria than Gram (−) bacteria [ 18 ], which is in line with the findings of the present study. Non-edible Ricinus communis L. seed oil exhibited antimicrobial activity against Bacillus subtilis, Aspergillus fumigatus and Aspergillus flavus [ 61 ]. In this study, moderate to lower concentrations of rubber seed oil showed higher activities against tested microorganisms.…”

Optimization and characterization of oil extracted from Croton macrostachyus seed for antimicrobial activity using experimental analysis of variance

“…The presence of phenolic compounds has been found to have a growth inhibition effect against different bacteria whereas presence of terpene in the oil has an effective inhibition growth in the antifungal activity. Thus, Croton macrostachyus seed oil has a properties of cytotoxicity and phototoxicity (Saha et al, 2015). The presence of tannin in the oil is used for antimicrobials by donating hydrogen atoms or electrons and acting as secondary antioxidants by retarding oxidating and bonding Fe 2þ to restrict the reaction steps in the Fenton reaction.…”

“…Antimicrobial agents play a great role in diminishing the caused by microorganisms like bacteria and fungus. However, reducing the infectious disease by microbial agents is a burden for the global community as resistant pathogens and extent of the effectiveness of antibiotics (Meresa et al, 2019;Saha et al, 2015). Therefore, a source of new antimicrobial agents with possibly novel mechanisms of different natural plant parts-based products can be used for this infectious disease (Abdulrasheed et al, 2016).…”

Traditional Medicine Analysis and Sustainable Use of Korean Pond Wetland Plants in the Agricultural Landscape

“…TM using the seeds of wild plants mainly uses the oils extracted from them [82,83]. Extracting oil from seeds has an extensive record in TK, and in addition to medicinal use, oils have functioned as fuels and chemical materials [84]. However, it is possible that seeds are used less frequently than other plant parts because it is difficult to collect them when the period of their production is short.…”
