A series of chiral thioureas (1 - 17) were synthesized from and tested for their anticholinesterase, tyrosinase, and urease enzyme inhibitor activities. Various phenylisothiocyanates were added to solution of ˪-cysteine in methanol: water (1 : 1 v / v) at room temperature and stirred for 24 h. The precipitated solid was recrystallized from n-butanol. Pure compounds were characterized by NMR (1 H and 13C), FTIR, and CHNS.

Fractions yielded from Phellinus gilvus fruiting bodies by liquid-liquid partition of methanol extract contained various bioactive compounds such as phenolics, flavonoids and terpenes. Butanol, water and ethyl acetate fractions had large amount of phenolics, 158.12 - 247.31 mg of gallic acid equivalents (GAE)/g and low amount of flavonoids, 21.74 - 36.05 mg of quercetin equivalents (QE)/g.

This study was the first fatty acid analysis and biological activity report on an endemic Achillea species, Achillea cappadocica Hausskn. et Bornm. The major compounds in the fatty acid were identified as oleic (34.7%), palmitic (23.1%), and linoleic acids (20.6%). The methanol and water extracts indicated higher ABTS cation radical scavenging activity than that of α-tocopherol and BHT at 100 µg/mL. The acetone extract showed 70.62% inhibitory activity against butyrylcholinesterase at 200 µg/mL. The acetone and methanol extracts exhibited moderate antimicrobial activity.

The active methanol extracts were successively partitioned with organic solvents such n-hexane, ethyl acetate and butanol to yield organic layers. Among of the resulting organic layers, n-hexane and ethyl acetate layers of the two plants displayed effective inhibition against various filamentous fungal and bacterial growth. Through bioassay guided isolation, 1,8 dihydroxy anthraquinones and their derivatives were isolated from those bioactive layers using silica gel, reverse phase and sephadex LH20 column chromatography.

The volatile components of essential oil (EO), SPME, and SPME of solvent extracts (n-hexane, methanol, and water) obtained from fresh Serapias orientalis subsp. orientalis(Soo) were analyzed by GC-FID/MS. EO of Soo gave 11 compounds in the percentage of 99.97%; capronaldehyde (37.01%), 2-(E)-hexenal (23.19%), and n-nonanal (19.05%) were found to be major constituents. SPME GC-FID/MS analyses of fresh plant and solvent extracts of Soo revealed 7, 12, 7, and 4 compounds within the range of 99.7% to 99.9%. Limonene (76.5%, 41.7%, and 61.

This study was conducted to investigate the physicochemical, phytochemical, in vitro antidiabetic and anticancer potential of Olea ferruginea R bark. After extraction using Soxhlet, in vitro antidiabetic and cytotoxic activity on human hepatocellular carcinoma (HepG2) cells was assessed by nonenzymatic glycosylation of hemoglobin assay, alpha-amylase inhibition assay, glucose uptake by yeast cells, and 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide assay, respectively, and gene expression via real-time polymerase chain reaction.

Tagetes patula is used to treat cancer patients in alternative healthcare systems. However, its cytotoxic and genotoxic effects have not been reported. Therefore, the methanol extract of T. patula flower, the ethyl acetate fraction, and the pure compound patuletin were evaluated using the Allium test. The methanol extract and fraction contained ~3% and ~36% patuletin, respectively, with ~98% purity. The methanol extract caused inhibition of Allium root growth displaying an IC50 value of ~500 µg/mL, while the fraction and patuletin were more potent by ~2 and ~5 times, respectively.

The antifungal activities of methanol extracts from different plant parts of G. superba viz., rind, rhizomes, leaves flower and seeds were evaluated by in vitro. In different extracts tested, seed extract (82.45%) was found to possess the highest mycelial inhibitory activity at 100 per cent concentration when compared to the others followed by rind (82.33%), rhizome (82.06%), leaves (77.45%) and flower (76.39%) extract was also inhibit the mycelial growth of F. oxysporum.

Experiments were carried out to determine the insecticidal activity of Aegle marmelos Correa against Callosobruchus chinensis L. in the laboratory. Plants were extracted with petroleum ether, methanol, ethanol and water by using Soxhlet apparatus and tested against adult of C. chinensis. Plant extracts were showed insecticidal activity by affecting through mortality, oviposition deterrence and inhibition of F1 adult emergence.

The present investigation was undertaken for in vitro screening of antibacterial activities of different extracts (ethyl acetate, methanol and benzene) of various plant parts of Achyranthes aspera, Azolla pinnata, Cissus quadrangularis. In vitro antibacterial efficacy of plants selected was assessed by well diffusion method against pathogenic bacteria such as Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli. The ethyl acetate extract of Cissus quadrangularis exhibited highest zone of inhibition against S. aureus (25±1.3mm) followed by Achyranthes aspera (20.0±0.

Antibacterial activities of Black pepper fruit extract were studied against some bacterial strains as- Pseudomonas fluorescens, Pseudomonas aeruginosa, Klebsiella pneumoniae, Proteus vulgaris, and Bacillus subtilis. The black pepper fruit extracts were prepared in four organic solvents as methanol, ethyl acetate, chloroform and benzene. Effectiveness against bacterial strains showed by all extract (which prepared by organic solvent) but the benzene extract showed the maximum growth inhibition 81.20% against Klebsiella pneumoniae bacteria at 100µl/ml extract concentration.

This study was conducted to evaluate the effect of crude and different solvent extract of Leaf of Lantana camara, an aggressive invasive weed against plant pathogenic fungi Colletorichum falcatum causing Red rot of sugarcane disease under in vitro conditions. Aqueous crude extract and solvent extracts such as extracts Methanol, Ethyl acetate, Chloroform were tested at 2mg/mL, 4mg/mL and 8mg/mL concentrations. Results revealed that all the 3 solvent extracts showed significant inhibition at higher concentrations when compared to the Standard Fluconazole (15μg/ml).

The protein and non protein parts present in the leaves of Lippia nodiflora were separated and test their nematicidal activity against egg hatching and juvenile mortality of Meloidogyne incognita. The non protein part was found to inhibit the root knot nematode egg hatching under in vitro conditions. Leaf extraction was done with different solvent such as petroleum ether, chloroform methanol using soxhlet apparatus and the residue was discarded.
