Cannabis sativa L. is a medicinally important weed of family Cannabaceae generally grows along road-sides and waste-lends in Punjab, Pakistan. In the present study, antifungal effect of leaf extract of this weed was assessed against Aspergillus flavipes. Methanolic leaf extract of the weed was partitioned into five fractions using organic solvents of variable polarities. A range of concentrations (1.562 to 200 mg mL-1) of each fraction was used in laboratory bioassays. n-Butanol fraction showed the highest antifungal activity followed by chloroform and n-hexane fractions causing 68–82%, 52–82% and 42–82% decrease in biomass of A. flavipes. Ethyl acetate showed a moderate antifungal potential while aqueous fraction showed the least antifungal activity causing 47–76% and 38–73% reduction in fungal biomass, respectively. This study concludes that n-butanol fraction of leaf extract of C. sativa is highly effective in controlling growth of A. flavipes.

Objective: The present study was carried out to investigate antimicrobial, antiradical and insecticidal potential of leaf and fruit of Gardenia gummifera L. f. (Rubiaceae).Methods: The leaf and fruits were shade dried, powdered and extracted by maceration process using methanol. Antibacterial activity was evaluated against Gram positive and Gram negative bacteria by Agar well diffusion assay. Antifungal activity was determined against six seed-borne fungi by Poisoned food technique. Antiradical activity of leaf and fruit extracts was evaluated by 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2-azinobis 3-ethylbenzothiazoline 6-sulfonate (ABTS) radical scavenging assays. Insecticidal activity of leaf and fruit extracts, in terms of larvicidal and pupicidal activity, was assessed against larvae and pupae of Aedes aegypti.Results: Both the extracts inhibited all test bacteria. Marked antibacterial activity was displayed by fruit extract when compared to leaf extract. S. epidermidis and E. coli were inhibited to highest and least extent by both extracts respectively. Fruit extract was found to exhibit higher antifungal effect when compared to leaf extract. Leaf extract and fruit extract exhibited highest inhibitory activity against A. niger and A. flavus respectively. Leaf and fruit extracts scavenged DPPH radical’s dose dependently with an IC50 value of 49.01µg/ml and 2.53µg/ml respectively. The scavenging of ABTS by leaf and fruit extracts was dose dependent and the IC50 value for leaf and fruit extract was 2.58µg/ml and 2.31µg/ml respectively. Fruit extract was shown to exhibit marked antiradical activity when compared to leaf extract. Leaf and fruit extracts exhibited dose dependent insecticidal activity in terms of larvicidal and pupicidal activity and the susceptibility of larvae and pupae to extracts was in the order II instar larvae>IV instar larvae>pupae. Fruit extract displayed marked insecticidal potential when compared to leaf extract.Conclusion: Overall, fruit extract of G. gummifera exhibited marked antimicrobial, antiradical and insecticidal activity when compared to leaf extract. The plant can be used for developing agents/formulations effective against infectious microorganisms, oxidative stress and insect vectors that transmit dreadful diseases. The observed bioactivities could be ascribed to the presence of active principles which are to be isolated and characterized.

Solanum dasyphyllum belongs to the family of plants called Solanaceae, it is commonly called "Africa eggplant" and one of the medicinal plants used in the treatment of snake envenomation in the southwestern part of Nigeria, but investigation concerning its anti-venom activity has not been established. The present study evaluates the in-vitroenzyme inhibition potential of S.dasyphyllum leaf and fruit extracts against Naja nigricollis (Black-necked spitting cobra) venom. The inhibitory potential of S. dasyphyllum leaf and fruit on proteases, acetylcholinesterase, phospholipase A2 and hyaluronidase enzymes present in the snake venom was evaluated. The methanolic leaf and fruit extracts of S. dasyphyllum inhibited the activity of all enzymes evaluated, however, the leaf extract exhibited better enzyme inhibitory effect on N. nigricollis venom when compared with the fruit. This could be due to the presence of various phytochemicals in leaf and fruit extract.  This result substantiates the ethnomedicinal usage of S. dasyphyllum and would help to develop potent antidote therapy against N. nigricollis envenomation.

The plant Calliandra portoricesis had been widely used over the years in traditional medicine. Such uses included; treatment of swollen gum, tooth ache and inflammation, worm expeller, viperean venom antidote and more. This investigation was aimed at screening and anti-microbial evaluation of various leaf and root extracts of the plant. By this, explore substitution of root with leaf as excessive root harvesting could lead to shrub extinction. The dried and pulverized samples were subjected to successive extraction using solvents of varying polarities; n-hexane, ethyl acetate and 70% aqueous methanol. The respective extracts were concentrated en vacuo in a rotatory evaporator at temperature not exceeding 40°C. Seven human pathogens were selected comprising the G +ve, G-ve, fungi, group that was known to acquire resistance easily and nosocomial strains namely; Staphylococcus aureus, Escherichia coli, Bacillus subtilis, Klebsiella pneumoniae, Streptococus fecalis, Candida albican and Aspergillus nigar. Ciprofloxacin and fluconazole solutions served as the control reference standards. Agar well diffusion assay method was used and the Inhibition Zone Diameters (mm) of growth were measured to assess activities for all the extracts. The Minimum Inhibitory Concenyrations (MIC) and Total Activity (TA) were also determined. The experimental values indicated that both leaf and root materials of this plant exhibited anti bacterial and anti fungal properties on the selected human pathogens especially with respect to the reference control standards at P ≤ 0.05. Except for anthraquinones, the leaf though exhibited weaker activities than root for same quantity of materials showed close similarity in activity pattern. In this sense, with an appropriate quantitative adjustments, leaf material could effectively substitute the root for antimicrobial purposes.

ABSTRACT: In the current study phytochemical analysis and in vitro antifungal potential of fruits, leaves and stem of Lantana camara L. were studied. The phytochemical analysis indicated the presence of alkaloids, flavonoids, tannins, saponins, glycosides and terpenoids in fruit, stem and leaves of L. camara. The in vitro antifungal activity of fruit, stem and leaves of L. camara was tested against Colletotrichum gloeosporioides Penz. Different concentrations (1-5%) of methanolic extract of all the selected parts of L. camara were applied in vitro against the test fungus. The results of in vitro experiment revealed that higher concentration of methanolic fruit extract (5%) significantly reduced the biomass C. gloeosporioides up to 66%. This effective extract of L. camara was partitioned with n-hexane, chloroform, ethyl acetate and n-butanol. The bioactivity of these fractions was tested against C. gloeosporioides. The trials showed that 0.5% concentration of n-hexane fraction of methanolic fruit extract caused the highest reduction (45%) in the radial colony growth of the test fungus. This effective n-hexane fraction was selected for GC-MS analysis to identify various possible antifungal compounds. Cyclopropane, carboxylic acid, 5-heptonic acid, 2,2-dimethyl1-4-pentenoate and 2-Propyloctahydro-1-benzothiophene were identified as major compounds. This study can be concluded that L. camara fruit comprised of bioactive compounds which possess antifungal activity against C. gloeosporioides.

Objective: Phyllanthus emblica L. or amla is known for its therapeutic properties. The aim of the present study was to evaluate the antibacterial activity of aqueous Phyllanthus emblica fruit extract (APE) against eight pathogenic cultures and its application in green synthesis of silver nanoparticles. Methods: APE was screened for the presence of phytochemicals and its antibacterial activity was evaluated by agar well diffusion assay. The minimum inhibitory concentration (MIC) was quantified by broth macrodilution technique, and minimum bactericidal concentration (MBC) was determined. Further, APE was used in the biological synthesis of silver nanoparticles (AgNPs), which were characterized by an Ultraviolet–visible (UV-VIS) spectroscopy and Field emission gun-scanning electron microscopy (FEG-SEM) techniques. The antibacterial activity of the AgNPs was screened by agar well diffusion assay. Results: The zone of inhibition (ZOI) for APE was found to be in the range of 10.7–21.3 mm, for varying concentrations. The MIC values were in the range of 12.5% - 50% (v/v) and the MBC values indicated that a concentration of 50% (v/v) APE could kill 75% (6/8) test cultures. The presence of AgNPs was confirmed by UV-VIS spectroscopy and the surface-plasmon resonance peak was observed at 420 nm. The FEG-SEM analysis revealed that the most of AgNPs were spherical in shape and had 30-40 nm size range. All the test cultures were inhibited by the AgNPs and the average ZOI measured 19.25±2.7 mm. Conclusion: Phyllanthus emblica fruit extract might have therapeutic significance against pathogens and it can be used for green synthesis of silver nanoparticles. Keywords: Phyllanthus emblica, MIC, MBC, silver nanoparticles, UV-VIS, FEG-SEM.
