Objective: The present study is preplanned to assess the antimicrobial and analgesic activity of the collected plants of Diplocyclos palmatus from Moinabad, Ranga Reddy, Telangana. Methods: In this study, D. palmatus fruits were used to gain the ethanolic extract and were tested for the phytochemical screening, antimicrobial activity using agar diffusion method against Gram-negative bacteria (Escherichia coli) and Gram-positive (Bacillus) and to compare its effect with the marketed standard streptomycin, ciprofloxacin, and analgesic activity of plant was performed by tail clip, tails immersion, and radiant heat method. Results: The maximum zone of inhibition is shown in the Gram-negative bacteria (E. coli) compared to standard and control. The ethanolic extract of D. palmatus fruits was shown analgesic activity and it was found to be more remarkable when compared to the standard aspirin and control. From the results of three different methods at different dose of ethanolic extract (100 mg/kg, 200 mg/kg, 400 mg/kg followed by 0–5 min interval up to 30 min), tail immersion method at 200 mg/kg dose of the D. palmatus fruits extract was achieved good results i.e., in 10 min (11.4 ± 1.93) and 15 min (13.4 ± 1.63). In tail clip method, 400 mg/kg dose is in 10 min (11 ± 1.67) and 15 min (10 ± 0.707) achieved best output, while same thing radiant heat method 200 mg/kg dose of the D. palmatus fruits extract is in 10 min (11.3 ± 1.67) and 15 min (14 ± 1.82) achieved outstanding results. Conclusion: The analgesic and antimicrobial activity of ethanolic extract of D. palmatus fruits are more significant compared to the other part of D. palmatus. Hence, the study concludes that the plant is having both analgesic and antimicrobial activity, and therefore, it can be used for various therapeutic purposes and further analysis.

The present study was planned to characterize and analyze the antimicrobial activity of silver nanoparticles (AgNP) biosynthesized using a Coccinia indica leaf (CIL) ethanolic extract. The present study included the preparation of CIL ethanolic extract using the maceration process, which was further used for AgNP biosynthesis by silver nitrate reduction. Biosynthetic AgNPs were characterized using UV–Visible spectrometry, zeta potential analysis, transmission electron microscopy (TEM), scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray diffraction (XRD), and energy-dispersive X-ray (EDX) spectrometry. The biogenic AgNP and CIL extracts were further investigated against different bacterial strains for their antimicrobial activity. The surface plasmon resonance (SPR) signal at 425 nm confirmed AgNP formation. The SEM and TEM data revealed the spherical shape of biogenic AgNPs and size in the range of 8 to 48 nm. The EDX results verified the presence of Ag. The AgNPs displayed a zeta potential of −55.46 mV, suggesting mild AgNP stability. Compared to Gram-positive bacteria, the biogenic AgNPs demonstrated high antibacterial potential against Gram-negative bacteria. Based on the results, the current study concluded that AgNPs based on CIL extract have strong antibacterial potential, and it established that AgNP biosynthesis using CIL ethanol extract is an effective process.

Ancient Times

Since ancient times plant as sources of medicinal compounds have continued to play a dominant role in the maintenance of human health. To treat chronic and infectious diseases plants used in traditional medicine contain a wide range of ingredients. In this regard, Cassia auriculata L. (Caesalpiniaceae) is widely used in Ayurvedic medicine as a tonic, astringent and as a remedy for diabetes, conjunctivitis, ulcers, leprosy, skin and liver diseases. The aim of present study was to evaluate the antimicrobial activity of ethanolic extract of Cassia auriculata leaves and flowers (CALE & CAFE). CALE and CAFE exhibited broad spectrum antimicrobial activity against standard strains of Staphylococcus aureus, Escherichia coli and Bacillus subtilis and exhibited no antifungal activity against standard strains of Candida albicans and Aspergillus niger. Minimum inhibitory concentration (MIC) and Minimum bactericidal concentration (MBC) was carried out for CALE and CAFE. The results obtained in the present study indicate that the CALE and CAFE can be a potential source of natural antimicrobial agents.

The present study was aimed at the development of topical gel of extract of Mangifera indica L. seed kernel and evaluation of its in vitro antibacterial activity. Various extracts using different solvents were prepared and evaluated for in vitro activity against Propionibacterium acnes. Ethanolic extract of M. indica L. seed kernel exhibited the highest in vitro antimicrobial activity and was considered further. Topical gels of this ethanolic extract were prepared using different polymers such as Carbopol 974P, Xanatural 180 and Methocel K15M in varying concentrations. The topical gel of 10 % w/w ethanolic extract of M. indica L. seed kernel with 2% w/w Carbopol 974P was uniform and yellowish transparent with satisfactory spreadability. The developed gel showed greater in vitro antimicrobial activity as compared to marketed herbal cream. These results indicate the potential of topical gel of ethanolic extract M. indica L. seed kernel as anti-acne formulation developed from plant waste product.

Methods: Agar well diffusion method was employed to demonstrate the antimicrobial activity of leaves A. occidentale. Ethanol and aqueous extracts of the leaves were used against microorganisms, which included American type culture collection strains of Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Enterococcus faecalis, and Pseudomonas aeruginosa and the clinical isolates of Streptococcus pneumoniae, Candida albicans, MDR Escherichia coli, and MDR Klebsiella pneumoniae. Results: The ethanolic extract of leaves of A. occidentale showed significant antimicrobial activity. Aqueous extract had mild antifungal activity. Conclusion: Ethanolic extract of leaves of A. occidentale could be a good source for the antibacterials to combat MDR bacterial infections. Further studies are necessary for these potent plant extracts to evaluate the in vivo efficacy and toxicity.

The present study aimed to evaluate the efficacy of traditionally used antibacterial plants (Euphorbia prostrata, Schinus molle, Brickellia veronicaefolia and Lepidium virginicum) in Santa Rosa Range in Guanajuato against major mastitis-causing pathogens. The selected plants were phytochemically screened for alkaloids, flavonoids, polyphenols, saponins, anthraquinone, cardiac glycosides, steroids and terpenoids. Moreover, to achieve the main purpose of the present research, extracts of selected plants were tested for in vitro antibacterial activity against Staphylococcus aureus, Escherichia coli, Shigella spp., Bacillus subtilis, Clavibacter spp., Proteus vulgaris and Salmonella spp. All these bacterial were isolated from clinical mastitis in dairy cows. The results indicated that the ethanolic extract of the aerial part of L. virginicum exhibited the strongest antimicrobial activity, and it could be potential candidate specie for the development of novel veterinary drugs with low cost and fewer side effects.

Comparative study of plant extracts crude and aqueous, methanolic and ethanolic with antibiotics, provide evidence that calotropis procera extracts has the similar antibacterial activity as these antibiotics against test pathogens i.e. Salmonella typhi and E.coli. The analysis of antimicrobial activity of aqueous, methanolic and ethanolic extract of leaves and flower of Calotropis procera was carried out in disc method and also determined MIC value at 600nm through optical density using spectrophotometer. The zone of inhibition produced by extracts was examined and compares it with zone produced by antibiotics. The effect exhibited by ethanolic extract of leaves and flower was significantly greater than the aqueous and methanolic extract of leaves and flower. Crude extracts i.e. latex, leaves, fruit and flower crude extracts. Among them, flower crude extracts shows similar zone of inhibition to test anitibiotics.while in MIC value, we made different concentration of extracts and antibiotics.i.e for crude we made 25%, 50%.75% and 100% concentration of crude juice and for the aqueous, methanolic and ethanolic we made 0.5mg/mL,1mg/mL,2mg/mL,3mg/mL,4mg/mL, 5mg/mL and 6mg/mL in Dimethyl salfoxide, and same antibiotics concentration. Aqueous leaves extracts show MIC at 0.5mg/ml against E.coli while against Salmonella it shows MIC at 1mg/ml... We also determine phytochemical analysis for presences of different compounds in crude extracts. The obtained results provide a support for the use of Calotropis procera, in traditional medicine and suggest its further advance investigation.
