    GC-MS ANALYSIS OF BIOACTIVE COMPOUNDS PRESENT IN ETHANOLIC STEM BARK EXTRACT OF AN ENDEMIC PLANT CHIONANTHUS MALA-ELENGI (DENNST.) P.S. GREEN (OLEACEAE) (PDF)
    (EBSCO, 2020-04) Malathi K; Krishnaveni C; Sahithya S; Akila Shree J
    Traditional and herbal medicines are the most easily available health care remedies. Chionanthus mala-elengi (Dennst.) P. S. Green is an endemic tree species of the family Oleaceae. It is used in giddiness, epilepsy, wound healing and liver disease. Phytochemical studies of this plant have not been reported so far. The aim of the present study is to characterize the chemical constituents present in ethanolic stem bark extract of Chionanthus mala-elengi. Thirty grams of powdered stem bark was extracted using 150 ml ethanol in Soxhlet apparatus. The mixture was filtered. The filtrates were evaporated and the dried ethanolic stem bark extract was used for further studies. Gas Chromatography - Mass Spectrometry analysis provided different peaks indicating the presence of sixteen different phytochemical compounds. Thus, the qualitative determination of stem bark ethanolic extract of C. mala-elengi using GC-MS analysis revealed the presence of various bioactive compounds which is used for different ailments by traditional practitioners.

    POTENTIAL UTILIZATION OF A WEED PROSOPIS JULIFLORA LEAF EXTRACT NANOPARTICLE FOR DYE DEGRADATION AND ANTIBACTERIAL ACTIVITY
    (Bioremediation and Green Technologies, 2021-04-09) Sahithya S; Krishnaveni C
    The present study was conducted to evaluate the silver nanoparticle synthesized using leaf extract of Prosopis juliflora. For possible dye degradation and antibacterial activity on Gram positive and gram-negative bacteria (Bacillus subtilis and Pseudomonas putida). The acetone extract showed good anti-bacterial activity against both the organisms, the inhibitory effect increased with increase in concentration of the extract. The presence of Silver Nanoparticles in the leaf extract was observed by reduction of silver ions into silver nanoparticles. Fourier Transform Infra-Red (FTIR) analysis was done to detect the functional groups which will promote the antibacterial and dye degradation capabilites.
