Abstract Background Adhatoda vasica L. is a medicinal plant, also known as Malabar nut in English, belongs to family Acanthaceae. It has been used traditionally to treat respiratory disorders like severe cough, cold, chronic bronchitis, asthma, tuberculosis, and other illnesses. The multifunctional range of bioactives found in it has piqued the interest of pharmaceutical companies, who are looking for more evidence-based ways to develop new formulations. Method Methanolic extract of Adhatoda vasica L. leaves (MEAV) was analysed by hyphenated gas chromatography-mass spectroscopy for identification and characterization of its bioactives and traditional therapeutic claim. Widely anticipated DPPH method was used to determine the antioxidant activity of MEAV. Results The major compounds revealed in MEAV leaves are 1,3,5-triazine-2,4,6-triamine (3.06%); 2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one (5.35%); 5-hydroxymethylfurfural (16.82%); 2-butylphenol (6.85%); 3,4-dihydroxy-5-methyl-dihydro-furan-2-on (2.5%); 2(OR 3)-(1,1-dimethylethyl)-4-methoxyphenol (3.52%); megastigmatrienone 3 (1.02%); tetradecanoic acid (1.52%); vomifoliol (0.58%); oxalic acid, cyclobutylhexyl ester (6.03%); hexadecanoic acid (6.06%); 4-ethyl-2-oxo-2,5,6,7-tetrahydro-1H-cyclopenta[B]pyridine-3-carbonitrile (10.08%); phytol (2.01%); and vitamin E (3.18%). A significant reduction in free radical against DPPH was observed, which revealed antioxidant potential of MEAV. Conclusion Methanolic extract of Adhatoda vasica L. leaves consist of both polar and nonpolar components. GC-MS analysis was used to identify these compounds. The current work validates that the antioxidant activity of methanolic extract attributed to the presence of compounds like vitamin E, alkaloid, and terpene.

Sartoria hedysaroides Boiss and Heldr. (Fabaceae) is an endemic plant of Turkey that has received little scientific consideration so far. In the present study, the chemical profiles of extracts from the aerial part and roots of S. hedysaroides obtained using solvents with different polarities were analyzed combining integrated NMR, LC-DAD-MSn, and LC-QTOF methods. In vitro antioxidant and enzyme inhibitory activities were evaluated, and the results were combined with chemical data using multivariate approaches. Phenolic acids, flavonoids, ellagitannins, and coumarins were identified and quantified in the extracts of aerial part and roots. Methanolic extract of S. hedysaroides aerial part showed the highest phenolic content and the highest antioxidant activity and cupric ion reducing antioxidant capacity. Dichloromethane extract of S. hedysaroides roots showed the highest inhibition of butyryl cholinesterase, while methanolic extract of S. hedysaroides aerial part was the most active tyrosinase inhibitor. Multivariate data analysis allowed us to observe a good correlation between phenolic compounds, especially caffeoylquinic derivatives and flavonoids and the antioxidant activity of extracts. Acetylcholinesterase inhibition was correlated with the presence of caffeoylquinic acids and coumarins. Overall, the present study appraised the biological potential of understudied S. hedysaroides, and provided a comprehensive approach combining metabolomic characterization of plant material and multivariate data analysis for the correlation of chemical data with results from multi-target biological assays.

Water extract of Acacia seyal bark is used traditionally by the population in Djibouti for its anti-infectious activity. The evaluation of in vitro antibacterial, antioxidant activities and cytotoxicity as well as chemical characterization of Acacia seyal bark water and methanolic extracts were presented. The water extract has a toxicity against the MRC-5 cells at 256 μg/mL while the methanolic extract has a weak toxicity at the same concentration. The methanolic extract has a strong antioxidant activity with half maximal inhibitory concentration (IC50) of 150 ± 2.2 μg/mL using 1-diphenyl-2-picrylhydrazyl (DPPH) and IC50 of 27 ± 1.3 μg/mL using 2,2′-azino-bis 3-ethylbenzthiazoline-6-sulphonic acid (ABTS) radical methods. For ferric reducing/antioxidant power (FRAP) assay, the result is 45.74 ± 5.96 μg Vitamin C Equivalent (VCE)/g of dry weight (DW). The precipitation of tannins from methanol crude extract decreases the MIC from 64 µg/mL to 32 µg/mL against Staphylococcus aureus and Corynebacterium urealyticum. However, the antioxidant activity is higher before tannins precipitation than after (IC50 = 150 µg/mL for methanolic crude extract and 250 µg/mL after tannins precipitation determined by DPPH method). By matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) analysis, the results showed that the condensed tannins consist of two types of catechin and gallocatechin-based oligomers. The fractionation led to the identification of three pure compounds: two flavanols catechin and epicatechin; one triterpene as lupeol; and a mixture of three steroids and one fatty acid: campesterol, stigmasterol, clionasterol, and oleamide.

Bio-sourced substances used for crop protection in natural and organic farming have a positive impact both on human and environment health: plant extracts are effective to stimulate plant defense against pests and diseases, with no toxic effect and they could be classified as basic substances. The chemical characterization of thyme and tansy extracts were carried out with ICP and NMR techniques for the analysis of elemental content and organic components. Antioxidant activity was evaluated by DPPH method. Phytostimulant effects of extracts were evaluated on zucchini crop in a preliminary field test. Vegetative plant conditions were assessed by measuring the chlorophyll content. The 1% extracts were chosen for field trial because of their maximum antioxidant activity (over 80%) and their cheapness compared to 2% concentration. NMR showed that the spectrum of tansy highlighted the phenolic fraction in 6-9 ppm region and, in particular, at 5.9 ppm the signals of thymol, a peculiar antioxidant compound; while the spectrum of thyme is less significant. The field trial results showed a higher fruit yield and a positive effect on plant growth in treated plants respect to control ones, due to the composition and antioxidant activity of both plant extracts. In fact, thyme extract treated plants showed a yield equal to 6,4 kg per plant, higher than no treated ones, 5,1 kg per plant; also tansy extract induced a higher yield respect to control plant, respectively 5,6 and 3,9 kg per plant. The results obtained indicate the role of the extracts investigated as basic substances.
