Zanthoxylum alatum (Z. alatum), an important medicinal plant is used for various ailments including chest infection, cough, cholera, fever, stomach disorders, gas problems, indigestion, piles, toothache, gum problems, dyspepsia and stomachic worldwide. Keeping in view the medicinal potential of this plant, fruit and leaves methanolic (MeOH) extracts were prepared, evaluated for antioxidant activity by 1,1-diphenyl-2-picrylhydrazyl (DPPH) and for antibacterial potential by well diffusion and macrodilution methods in-vitro. Our results confirmed that Z. alatum fruit and leaves extracts have significant antioxidant activity with IC50 values 0.28 ± 0.07 mg/ml and 0.34 ± 0.05 mg/ml, respectively. The inhibitory trend at highest tested concentration (120 mg/ml) at 24 hr incubation in well diffusion method was recorded as 0.39, 0.30, 0.28, 0.27 and 0.18 cm against S. pyogenes, B. cereus, E. coli, S. aureus and S. enterica for leaf extract, respectively. In case of fruit extract inhibitory trend at highest tested concentration was observed as 0.33, 0.32, 0.31, 0.30 and 0.28 cm against S. aureus, S. enterica, S. pyogenes, B. cereus and E. coli, respectively. The fruit extract showed higher zones of inhibition than leaves extracts against all the test bacteria except S. pyogenes. Moreover, highest zones of inhibition were observed at lowest incubation (24 hr) and lowest zones were observed at highest incubation period (72 hr) for all tested concentrations. Macrodilution method showed antibacterial susceptibility in liquid medium with different levels of IC50 values ranging from 1.6±0.13 mg/ml to 10.3±0.7 5mg/ml. Interestingly, none of the tested bacteria showed resistance against any of the test extract in well diffusion or macrodilution method expressing the Z. alatum as potent candidates to kill bacteria in semisolid or in liquid medium to fulfill medical needs in future.

Background: Emerging resistant Candida species become a severe problem for public health. The study aims to examine the efficacy of Terminalia subspathulata bark and fruit extracts as an alternative source of antifungals for resistant strains of Candida species. Methodology: Candida albicans was isolated between 4–5th interdigital foot space and C. parapsilosis were isolated from the left-hand third finger of male patients. Morphological and molecular methods identified the isolates. Antifungal susceptibility testing (AFST) was determined using azole derivatives, amphotericin B (AmpB) and echinocandins based on E-test and broth microdilution (BMD) methods. The AFST activity of the 10 μL methanolic extracts with concentrations between 1.25–10 mg/mL was assessed by disk diffusion method according to CLSI guidelines. Results: The AFST results showed total resistance to all azoles (FLU, MIC ≥ 256 μg/ml and VOR, ITR and POS each with MIC ≥ 32 μg/ml). The BMD method agreed with E-test MICs. The T. subspathulata bark extract tested indicated activity on the C. albicans lawn with the zone of inhibition between 9–13 mm. The fruit extract indicated zone between 8–10 mm. Candida parapsilosis indicated susceptibility to bark extract with the zone of inhibition between 10–15 mm, while the fruit extract showed zone between 8–13 mm. Conclusion: Despite azole resistance, the extracts showed good activity against the isolates. Findings showed alternatives to AmpB and echinocandins because of toxicity and parenteral administration, respectively. Based on our findings, our study first reports the medicinal value of T. subspathulata.

Objectives: Dichapetalum gelonioides (Roxb.) Engl. belongs to the family Dichapetalaceae. In the present study, we investigated antibacterial, antifungal and antioxidant activity of methanolic extract of leaf and fruit of D. gelonioides. Methods: Maceration process was carried out for extraction of leaf and fruit of D. gelonioides. Agar well diffusion method was employed to evaluate antibacterial activity of extracts against gram positive and gram negative bacteria. Poisoned food technique was performed to investigate antifungal activity of extracts against two seed-borne fungi. Antioxidant activity was evaluated by DPPH radical scavenging and ferric reducing assays.  Results: Both leaf and fruit extracts were effective in causing inhibition of all test bacteria. Highest and least inhibitory activity was observed against Bacillus cereus and Escherichia coli respectively. Both Aspergillus niger and Bipolaris sp. were inhibited to >50% by leaf and fruit extracts. Extent of inhibition of Bipolaris sp. was slightly higher when compared to A. niger. Both leaf and fruit extracts showed a dose dependent scavenging of DPPH radicals with high activity being showed by leaf extract. Leaf extract was shown to exhibit marked reducing potential than fruit extract. Conclusions: Overall, leaf extract was shown to be more effective in displaying antioxidant activity and causing inhibition of bacteria and fungi when compared to fruit extract. The results indicate that the plant possess active principles which are to be purified, characterized and subjected for antimicrobial and antioxidant assays in further studies.

Antioxidant And Antimicrobial Activity

Fruit extracts of the Chaenomeles species are a rich source of compounds having health-promoting properties, while their distribution between the species and cultivars varies significantly depending on both genotype and environmental threats. This study aimed at discovering antioxidant and antimicrobial potential of the secondary metabolites of fruit and waxes of fruit cuticular of introduced Ch. cathayensis and Ch. × californica plants. The sum of detected polyphenols in the isopropanolic fruit extracts varied slightly between the species, while significant excesses in indices were seen for both species peel extracts as compared to pulp extracts. Antimicrobial assays carried out by disc diffusion method showed notable activity of the fruit peel and pulp extracts of both species against all tested Gram-negative and Gram-positive bacterial strains, and two Candida strains as well. Pseudomonas aeruginosa strain was the most resistant to the action of both fruit extracts, especially peel extracts of Ch. cathayensis fruits. As identified by gas chromatography-mass spectrometry (GC-MS) assays, chloroformic extracts from the fruits of cuticular waxes of Ch. cathayensis and Ch. × californica contained six prevailing fractions: aldehydes, alkanes, alcohols, esters, fatty acids and various terpenoids. The predominant compounds were tetrapentacontane (21.8% of total amount) and heptacosanal (23.1% of total), respectively in the cuticular waxes of Ch. cathayensis and Ch. × californica. Cinnamaldehyde, cis-9-hexadecenal, hexadecanoic acid, oleic acid, olean-12-ene-3,28-diol (3. beta), lupeol, diisooctyl phthalate, 9-octadecenoic acid, 1,2,3-propanetriyl ester, 1,3,12-nonadecatriene-5,14-diol and some other identified compounds are well-known for their bioactivity, indicating the feasibility of studying the antimicrobial potential of plant fruits.

Antibacterial Potential

Zinc oxide nanoparticles have been biosynthesized with the help of Neolamarckia cadamba leaf and fruit extracts. ZnO nanoparticles were tested for antibacterial activity before and after calcination against Gram positive (Staphylococcus aureus, Bacillus subtilis) as well as Gram negative micro-organisms (Escherichia coli, Pseudomonas aeruginosa) within the concentration range 0.625–10 mg/mL with the help of well diffusion technique. Higher antibacterial potential has been observed in ZnO nanoparticles synthesized using leaf extract in comparison with those synthesized using fruit extract. Increased antibacterial activity was observed before calcination as compared to after calcination. ZnO synthesized using leaf extract were observed to show significant antibacterial potential against E. coli, S. aureus along with P. aeruginosa before calcination as well as against E. coli after calcination. Similarly, ZnO nanoparticles synthesized using fruit extract exhibited antibacterial activity against E. coli and P. aeruginosa before calcination and against E. coli after calcination. Both the ZnO nanoparticles before and after calcination did not show any antibacterial activity against B. subtilis. Thus, ZnO nanoparticles can serve a dual purpose by its application as an antibacterial agent against susceptible micro-organisms as well as biocompatible carrier system for drug delivery applications in case of non-antibacterial properties by virtue of its inertness as well as easy disposal.
