Objective: This study was conducted to assess the phytochemical constituents in Punica granatum L. Leaf extracts (PGLE) using standard methods.Methods: The leaf powder was extracted using solvents namely aqueous, hydroalcohol, ethanol, ethyl acetate and n-hexane. Qualitative and Quantitative phytochemical screenings of PGLE were assessed by standard methods.Results: All the leaf extracts were positive for a wide range of bio-active compounds except n-hexane. The result has showed that the maximum amount of total phenols (394.16 mg/g DW of extract), total tannins (210.5 mg/g DW of extract), flavanoids (147.4 mg/g DW of extract) and total triterpenoids (112 mg/g DW of extract) were noted in ethanolic extract of P. granatum leaf (EPGL). The biological assay revealed that relevant amount of carbohydrate, protein, lipid and alkaloid in EPGL.Conclusion: The findings of this study concluded that the EPGL had potential bioactive substances that may be used as pharmaceutical ingredients for formulation of new or prospective potent drug to cure wide range of metabolic diseases.

Acalypha Indica

The herb <em>Acalypha indica </em>which belongs to Euphorbiaceae family has multiple medicinal properties which include anti-oxidant, anti-bacterial, anti-fungal, anti-inflammatory, antiulcer, anti-helmintic, anti-cancerous, anti-venom, and neuro-protective activity. The present study was designed to evaluate the phytochemical, antimicrobial and anti-oxidant activity of <em>Acalypha indica </em>leaves extracts in different solvent extractions like methanol, hexane, ethyl acetate and petroleum ether. Fresh leaves of the plant were collected and shade dried. Dried leaves were milled to obtain powder. Powder was subjected to soxhlet extraction using solvents and extracts were successively obtained. Phytochemical analysis was conducted following standard methods.  Phytochemical analysis showed the presence of Alkaloids, Phenols, Saponins, Flavanoids and Amino acids. Leaf extract of methonal have shown the highest anti-oxidation capacity than hexane, ethyl acetate and petroleum ether. Anti-microbial activity has been performed on microbes like <em>Bacillus sps</em>, <em>E.coli,</em> <em>Psuedomonas sps</em> and <em>Streptococcus sps.</em> A highest value of zone of inhibition was found in methanol extract against <em>E.coli.</em> These results provide evidence that <em>Acalypha indica </em>leaf extract possesses vital phytochemicals, antimicrobial and antioxidant properties. Hence this plant can be studied further for drug analysis for finding potent medicines for diseases.

In Vitro Antioxidant Activity

The presence of various bioactive components makes it necessary to analyse plants for their potential to act as a source of useful treatments and cures for many inflammatory, infectious and pathogenic diseases. This study was carried out to determine phytochemicals and in-vitro antioxidant activities of the leaf extracts of Acalypha godseffiana. The leaves of A. godseffiana were collected, dried, pulverized and extracted separately with methanol and water using maceration method. The extract was concentrated in vacuo with rotary evaporator at 40oC. The extracts were subjected to quantitative phytochemical analysis and different anti-oxidant analytical procedures like FRAP, DPPH etc to determine the radical scavenging capabilities. The results of phytochemical analysis estimated the quantities and revealed the presence of alkaloids, flavonoids, tannins, saponins and terpenoids which varied in both extracts. The methanol and aqueous extracts exhibited antioxidant activities with relatively high IC50 (IC50 = 3.67 ìg/ml and 4.42ìg/ml respectively) which accounted for a low free radical-scavenging activity when compared with the reference antioxidant, vitamin C (IC50 = 1.51ìg/ml). The results of the study indicates that A. godseffiana leaf extracts contain secondary metabolites and possesses antioxidant properties.

This study aimed to determine phytochemical contents, antibacterial properties, and antibiotic modulating potential of Punica granatum leaf extracts: hexane, chloroform, ethyl acetate, ethanol, and aqueous extracts as well as an extract enriched with total oligomer flavonoids (TOFs). The TOF extract contained the highest value of phenols and flavonoids. Rutin, luteolin, gallic acid, and ellagic acid were determined by HPLC analysis of this extract. The antibacterial activity was assayed by the disc diffusion method and microdilution method against Staphylococcus aureus and Escherichia coli standard ATCC strains and clinical isolates resistant strains. The TOF extract was the most active against all tested strains. The checkerboard method was used for the determination of synergy between two antibiotics (amoxicillin and cefotaxime) and P. granatum leaf extracts. The best synergistic interaction was found with TOF extract combined with amoxicillin for penicillin-resistant E. coli and penicillin-resistant S. aureus. These results can be assigned to tannins, flavonoids, and phenolic acids found in P. granatum leaf extracts. Pomegranate leaf extracts or active compounds isolated from these extracts could be used to fight the emergence and spread of resistant bacterial strains.

Background: Nowadays microbial infections are considered the most important causes of morbidity and mortality. Various microorganisms including biofilm-forming bacteria reported playing a crucial role in such public health concerns. On the other hand, the inefficacy of conventional antimicrobial agents may due to various reasons including drug resistance creates a need for the development of effective drug molecules. In this context, nanoparticles can be promisingly used in the management of all such concerns. Objective: The study aimed to evaluate antibacterial and biofilm removal efficacy of various metal nanoparticles against biofilm-forming bacteria. Methods: Various metal nanoparticles including silver (AgNPs), copper (CuNPs) and zinc oxide (ZnONPs) were synthesized from plant leaf extracts of Punica granatum, Citrus medica, and Annona squamosa, respectively. Results: Thus synthesized nanoparticles were evaluated for their antibacterial and biofilm removal efficacies against Enterococcus gallinarum, Staphylococcus haemolyticus, Enterobacter aerogenes, and Salmonella enterica serovar Typhi to propose a promising approach towards management of such pathogens. In vitro antibacterial study demonstrated that AgNPs showed the maximum efficacy against all the test bacteria followed by CuNPs and ZnONPs.
