Ethanolic Leaf Extract

Objective: The objective of this study is to analyze the bioactive compounds of the ethanolic leaf extract of Acacia caesia using gas chromatography-mass spectrometry (GC-MS) method and also screen the in vitro cytotoxic activity against HeLa-E 72 cancer cell line.Methods: The present research was carried out using GC-MS analysis, while mass spectra of the compounds found in the extract were matched with the National Institute of Standards and Technology and Wiley library. Cytotoxicity was assessed with 3-[4,5-dimethylthiazol-2-yl]2,5-diphenyltetrazolium bromide assay, and cellular morphological alterations were studied using phase contrast inverted light microscope of 400×. The ethanol extract of A. caesia was screened for their cytotoxicity at different concentrations (12.5–200 μg/ml), to determine the mean percentage (%) cell viability.Results: The results of GC/MS analysis showed the presence of 41 major compounds. In terms of percentage amounts, 1,8-diphenyl-3,4,10,11- tetrahydro[1,4]dioxino[2,3-g:5,6-g’]diisoquinoline, 6-(chloromethyl)-4-(3,4-dimethoxy-2-(phenylmethoxy)-phenyl)-3-methyl-2-yridinecarboxylate, and 2’,4’,6’-Trinitro-5’-phenyl-1,1’:3’,1”-terphenyl were predominant in the extract and have the property of antioxidant, antidepressant potential, antibacterial activity, cytotoxic, diabetic, and induced brain activity. The results of cytotoxicity at highest concentration (200 μg/ml) of the cells became rounder, shrunken and showed signs of detachment from the surface of the wells denoting cell death.Conclusions: From this study, it is obvious that A. caesia leaf extracts contain various bioactive constituents with a wide range of medicinal properties which is used to treat multiple disorders and it also gives a detailed insight about the phytochemical profile which could be exploited for the development of plant-based drugs. Further, the ethanolic extract of A. caesia exhibits potent cytotoxic activity against HeLa-E 72 cell line.

Objective: The search for various phytotherapeutic compounds is on rise due to a complex multifactorial phenomenon called drug resistance. The present study investigates the cytotoxic, antioxidant, and antiproliferative potential of methanolic extracts of Clitorea ternatea, Averrhoa bilimbi, Phyllanthus acidus, Tecoma stans, Curcuma aromatica, Anethum graveolens, Adhatoda vasica, Markhamia lutea, Spathodea companulata, and Adenanthera pavonina.Methods: The plant parts were extracted with methanol and screened for 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2’-azino-bis(3- ethylbenzothiazoline-6-sulfonic acid) (ABTS) free radical scavenging abilities. The cytotoxic activity of the extracts was investigated on HeLa and HCT116 cells through 3-(4,5-dimethylthiazol2yl)-2,5-diphenyl tetrazolium bromide (MTT) assay, and cell cycle was analyzed by flow cytometry to determine the antiproliferative activity of the extracts. The stem extract of A. pavonina was further subjected to gas chromatography-mass spectrometry (GC-MS) analysis for purification of the compounds of interest. A two-way ANOVA was done to estimate the effect of the extract between samples remembered at p<0.05 level.Results: Among all the studied samples, the extract of A. pavonina (stem) showed significant scavenging activity of 70.23% and 76.32% of scavenging compared to 74.58 % and 81.13% of that of reference standard in ABTS and DPPH assay, respectively. GC-MS analysis of the extract revealed the presence of 17 phytocompounds. MTT assay revealed that this extract (SB19) had promising cytotoxic activity against the two cancer cell lines, HCT116 and HeLa with inhibitory concentration 50% IC50 values of 25.86±0.21 μg/ml and 39.89±0.11 μg/ml, respectively. The extract treatment caused significant arrest in G2M phase of cell cycle.Conclusion: A. pavonina (stem) extract displayed significant antioxidant and antiproliferative activity and can be considered as a potential candidate drug for anticancer studies.

Abstract Background Recent advances in the diversified anti-diabetic drugs have appeared in the startling increase in the count of poisoning cases. The epidemics of diabetes mellitus are increasing; hence, the no. of anti-diabetic drug users raised by 42.9%. The use of glimepiride raised to 24%. As the toxicity and drug cases are also escalating with increasing epidemics of diabetes mellitus, a novel gas chromatography-mass spectrometry (GC-MS) method for detecting glimepiride in biological matrices is developed. Results Liquid-liquid extraction method was employed by using 1-butanol: hexane (50:50, v/v) under an alkaline medium, and then back extraction was done via acetic acid. Distinct derivatization techniques were employed for the sample preparation for GC-MS analysis, i.e., silylation and acylation. Derivatization approaches were optimized under different parameters, i.e., reaction temperature and reaction time. N-Methyl-N-(trimethylsilyl) trifluoroacetamide [MSTFA] was found to be the best sound derivatization reagent for the GC-MS analysis of glimepiride. Total ion current (TIC) mode was selected for the monitoring of ions of trimethylsilyl (TMS) derivative of glimepiride with an m/z ratio of 256. Distinct parameters like specificity, carryover, stability, precision, and accuracy were evaluated for validating the identification method. The GC-MS method is found to be linear and illustrated within the range 500 to 2500 ng/ml with the value of R2 (coefficient of determination) at 0.9924. The stability of the extracted and derivatized glimepiride was accessed with regard to processed/extracted sample conditions and autosampler conditions, respectively. Accuracy at each concentration level was within the + 15% of the nominal concentration. Precision (%) for the interday and intraday analysis was found to be in the respectable spectrum. Conclusion Henceforth, the proposed GC-MS method can be employed for the determination of glimepiride in biological matrices.

 Objective:The objective of this study is to characterize the phytoconstituents of Tiliacora racemosa Colebr. using gas chromatography mass spectrometry (GC-MS).Methods: Preliminary phytochemical and physicochemical analysis was carried out using standard procedures. GC-MS analysis of methanolic extract was carried out using Thermo GC-Trace Ultra version: 5.0, Thermo MS DSQ with a DB 35MS capillary standard non-polar column and gas chromatograph interfaced to a mass selective detector (MS DSQ II) with Xcalibur software.Results: Preliminary phytochemical screening revealed the presence of alkaloids, flavonoids, phenols, tannins, triterpenoids, steroids, proteins and amino acids, carbohydrates, saponins and coumarin. Quinones, anthraquinones, glycosides and fixed oil were absent. GC-MS analysis revealed the presence of 28 compounds of which quinic acid (retention times [RT]: 15.65) and inositol, 1-deoxy-(CAS) (RT: 19.24) was observed as abundant compounds.Conclusion: The presence of various bioactive compounds confirms the medicinal importance and it’s application for curing various diseases by traditional practitioners. However, isolation and characterization of potential bioactive compounds would lead to drug formulation.
