Antimicrobial and phytotoxicity activity of essential oils from waste leaves of Curcuma longa

Journal of Essential Oil Bearing Plants (2024)

Teikur Majaw RK Ranjan Jyostnarani Pradhan

AbstractCurcuma longa L. is a herbaceous crop that is used for wide applications. The economic importance of C. longa is the rhizome but the leaves remain as wastes. The present study aims to extract the essential oils from the waste leaves of four different varieties of C. longa and to evaluate the antimicrobial activity against plant pathogens and phytotoxic activities of essential oils on seed germination. The major components of EO were monoterpenes with abundant percentage varying across the varieties. The major compounds in Rajendra Sonia were α-terpinolene (14.64%), m-cymen-8-ol (14.02%), 5-isopropenyl-2-methyl-7-oxabicyclo [4.1.0]heptan-2-ol (11.13%), in Rajendra Sonali were α-terpinolene (13,91%), m-cymen-8-ol (11.18%), exo-2-hydroxycineole (13.0%), in IISR-Alleppy Supreme were α-phellandrene (12.84%), α-terpinolene (7.77%), and in IISR-Roma were cis-2,3-pinanediol (17.55%), p-cymene (11.76%). EO exhibited notable antimicrobial activity against plant pathogens albeit to a different degree and in a dose-dependent manner. EO from Rajendra Sonali and Roma inhibited 74% of growth of Bipolaris oryzae as compared to the control while EO from IISR-Alleppy and Roma inhibited the growth of Xanthamonas oryzae more effectively as compared to other EO. Furthermore, EO exhibited phytotoxicity effect and inhibited germination of seeds by 62.91% in Triticum aestivum, 76.1% in Panicum sumatrense and 78.6% in Abelmoschus esculentus and inhibition increased significantly with increased concentration of the essential oils with the exception in Zea mays where inhibition was 20.6% and found not significant. The findings from the study suggest that EO from turmeric waste leave could be valorized and have potential for application in pest control management.Keywords: Essential oilsCurcuma longaAntimicrobialGermination

Morphological characterization and expression analysis of genes for antioxidants enzymes in gamma rays induced M3 mutants of sunflower (Helianthus annuus L.) cultivar TNAUSUF-7

International Journal of Radiation Biology (2022)

Ranjan Rajeev Sayanta Kundu Teikur Majaw Karma L. Bhutia

Purpose Objectives of the present investigation were to investigate the performance of mutant lines (mutant generation 3 (M3) generation) of sunflower obtained through gamma irradiations for yield and yield attributing traits including oil content (%), oil quality in terms of antioxidant activity and to investigate the expression of genes encoding antioxidant enzymes in control and gamma irradiated M3 lines.Materials and methods Mutant lines (M3 generation) of sunflower variety TNAUSUF-7 obtained from 100 and 130 Gray (Gy) doses of gamma irradiation were evaluated for several traits such as days to 50% flowering, days to maturity, head diameter, number of filled seeds and unfilled seeds per head, fertility %, oil content %, antioxidant activity of oil and expression of genes encoding antioxidant enzymes. All the data were analyzed using different statistical tools.Results Our results showed that the gamma irradiation dose of 100 and 130 Gy induced significant variations in yield and yield attributing traits especially for days to 50% flowering, days to maturity, fertility %, antioxidant property of sunflower seed oil and expression of genes encoding antioxidant enzymes.Conclusions From our results, it can be concluded that the gamma irradiations were effective in creating variations in terms of several traits in sunflower. Many desirable traits like reduced days to 50% flowering and maturity, increased fertility %, increased antioxidant activity of oil were observed in M3 lines. These M3 lines have the potential to be utilized as an inbred line in sunflower hybrid development or it could be used as a source of desirable traits in sunflower breeding programs.

Biochemical Characterization of Essential Oils Isolated from Post-Harvest Leaves of Curcuma longa L.

Indian Journal of Agricultural Biochemistry (2021)

Teikur Majaw C. Mukhim

Essential oils from the post-harvest leaves of Curcuma longa were evaluated in an attempt to demonstrate that these supposed-to be agricultural-wastes can serve as the raw materials. Curcuma longa, also called as turmeric, is well known for possessing many beneficial properties. Therefore, in this study, essential oils from leaves of post-harvested leaves of ten varieties of turmeric were isolated and their biochemical properties were characterized. Our results indicated that the waste leaves still contained a considerable amount of essential oils, which varies between 0.374–2.087 percent among varieties. The essential oils from each variety show antioxidant properties albeit to a different degree which corroborate with the presence of phenolic and flavonoid compounds. Although chemical composition varies, however, few major components common in all varieties include -pinene, eucalyptol, ar-curcumene, trans-nerolidol,/bisabolene, bisabolone, zingiberenol and phytone. Thus, the findings concluded that the waste leaves can still serve as the raw materials for essential oils and has potential for usage in various applications as an antioxidant.

Essential oils biosynthesis is differentially regulated at different developmental stages of Curcuma longa L.

Research Square (Research Square) (2024)

Teikur Majaw Sushil Kumar Bharti Anoop Kumar Mishra

Abstract Essential oils (EO) are plants secondary metabolites significant for plant’s defense and supplementary growth. These are synthesized in plants cells in response to various factors. Here, we demonstrate that essential oils extracted from leaves of Curcuma longa are differential expressed at different developmental stages. The EO yield was 1.13% at 4-month old, 1.79% at 6-month and 1.35% at 8-month old leaf in Rajendra Sonali variety. In the variety, Narendra Haldi, the essential oils yield was 0.81% at 4-month old, 1.75% at 6-month and 1.08% at 8-month old leaf. The number of compounds were 45, 41 and 42 in Rajendra Sonali and 47, 33 and 40 Narendra Haldi leaves at 4-, 6- and 8-month old leaves. Monoterpenes were the most abundant followed by sesquiterpenes. Terpinolene, accounts the highest component at 27.62%, 24.7% and 24.7% in Rajendra variety while it is 30.57%, 36.01% and 11.36% in Narendra haldi (NH) at three different stages. Differential genes expression showed that genes involve in biosynthesis of essential oils were highly expressed in 6-month old leaves. Most of the genes that acts as feeder pathway to EO biosynthesis such as carbohydrate metabolism are highly expressed in 6-month old leaves. The finding suggest that the essential oil content and chemical composition is due to the differential expression of genes involving in the essential oil biosynthetic pathway and the differential components may be used as a metabolic marker of developmental stages.
