“…Antibacterial activity of volatile compounds obtained through solvent extraction of Spirulina, red and brown algae was reported earlier (Ozdemir et al 2004;Karabay-Yavasoglu et al 2007;Demirel et al 2009), Linalool, terepenols, β-caryophyllene and other terepenoid compounds present in the SCCO 2 extract (Table 1) might also be contributing for the antimicrobial activity along with phenolics and flavonoid compounds.…”

Supercritical carbon dioxide (SCCO 2 ) extraction and fractionation of Spirulina platensis was carried out to obtain functional compounds with antioxidant, antimicrobial and enzyme inhibitory activities. Extraction of SCCO 2 was carried out using 200 g of Spirulina powder at 40ºC under 120 bar pressure with CO 2 flow rate of 1.2 kg h −1. SCCO 2 fraction obtained was further treated with hexane and ethyl acetate to identify its components. Individual components were identified by comparing mass spectra of samples with standard data and retention indices (RI) of C5-C20 n-alkanes mixture using the kovat index formula. The phenolic and flavonoid content of the SCCO 2 extract was found to be 0.34±0.01 g/100 g and 0.12±0.01 g/100 g respectively. The SCCO 2 extract had antioxidant activity with IC 50 value of 109.6 ± 3.0 μg mL −1 for DPPH (2,2-Diphenyl- respectively.

Azadirachta indica (Neem) has a dynamic role in various problems associated with human health. Each part of the Neem tree has some medicinal property and is thus commercially utilizable. The plant parts such as leaves, flowers, seeds, fruits, roots and bark have been used traditionally for the treatment of inflammation, infections, fever, skin diseases and dental disorders. The aim of this study is to identify and characterize the vital bioactive compounds from the Neem sap by Gas chromatography and Mass spectroscopy (GC-MS). The GC-MS analysis of the Neem sap revealed the presence of 30 volatile compounds. Among the 30 compounds, the most predominant compounds are fatty acids like Hexadecanoic acid and Pentadecanoic acid. Hence, this current attempt forms a basis for the biological characterization and importance of the compounds which could be exploited for future development of drugs.

The present study is devoted to construction of new antibacterial and anti-fungal agent based on combination of in situ synthesized silver nanoparticles with plants extract, while through a green synthesis Ag-NPs were synthesized at room temperature using Rosmarinus officinalis leaf extract. In this study, hydroalcoholic extracts have been used for with Ultrasonic method. Ultrasonication has recently received attention as a novel bioprocessing tool for process intensification in many areas of downstream processing. Antimicrobial activities of T. daenensis and S. marianum extracts in the presence and absence of Ag-NPs was investigated at concentrations between 12.5-50 mg/mL against Staphylococcus aureus (Gram-positive organisms), Escherichia coli (Gram-negative organisms), and fungal strains were Aspergillus oryzae, Candida albicans. Antimicrobial activity determined using agar disc diffusion method reveal that activities of Ag-NPs/T. daenensis were superior to Ag-NPs/S. marianum and extracts (T. daenensis and S. marianum). Medicinal plant extracts is able to synthesis the Ag-NPs as an eco-friendly and inexpensive method in large scale. The extract/Ag-NPs has good antibacterial and antifungal activity that candidate them as potential tool to combat against rapidly increasing antibiotic resistance. Antioxidant content of the extracts was also determined and demonstrated the highest antioxidant activities associated with the shoot of Thymusdaenensis (Total phenolic content: 198.71 ± 1.50 mg gallic acid equivalents/g of dried extract, DPPH: 48.80 ± 0.59 % inhibition and Total Flavonoid Content: 172.42 ± 1.43 mg rutin equivalents (RuE)/g of dried extract).
