Background: Polyherbal plant extracts which usually comprise of two or more plant parts often contain a wide array of key phytoactive constituents relevant in attaining greater therapeutic efficacy. The active constituents derived from individual plants are insufficient to provide attractive pharmacological action when compared to a combination of multiple herbs. Objective: To conduct phytochemical screening of polyherbal aqueous leaf extracts                            (PALE) and analysis of compounds present in it by gas chromatography-mass spectrometry (GC-MS). Materials and Methods: The polyherbal extract was prepared from the combined aqueous extracts of leaves of Alchornea cordifolia, Sorghum bicolor and Pennisetum glaucum using ratio 1:1:1 w/v. Phytochemical screening was done via standard analytical methods. The identification and characterization of compounds by GC-MS analysis was performed on gas chromatography system coupled with mass spectrometry. Results: The phytochemical analysis of PALE revealed the presence of phenols, saponins, flavonoids, alkaloids and tannins in varying quantities. GC-MS analysis of the extract depicts the presence of key bioactive compounds. Thirty-two bioactive compounds were identified with various retention time and % peaks. The major compounds identified in terms of % peak area are n-Hexadecanoic acid (6.72), Hexadecanoic acid, ethyl ester (7.28), 9,12-Octadecadienoic acid (16.54) and 9-Octadecenoic acid ethyl ester (12.92). Disulfide, dimethyl (0.04), 2-Methoxy-4-vinylphenol (0.28), 1-Dodecanol (0.85), 10-Phenyldecanoic acid (0.12), 1-Hexadecanol (0.75), Methoxyacetic acid, pentadecyl ester (0.27), 9-Octadecenoic acid (Z)-, phenylmethyl ester (0.16), Hexadecanoic acid, 2-hydroxy-1-(hydroxymethyl) (1.09), were among the minor compounds identified in the extract. From the study, 9,12-Octadecadienoic acid indicated the highest peak with a retention time of 20.556 minutes and % peak area of 16.54%. Conclusion: The presence of the revealed bioactive constituents in PALE may suggest its nutraceutical, pharmacological and therapeutic relevance. Therefore, in view of the medicinal importance associated with the observed bioactive constituents, further studies on the toxicity level of  the extract is advised subsequently.

Phytochemical Constituents

Rodent tuber (Typhonium flagelliforme Lodd.) is an Indonesian herbal plant from Araceae family which is highly potential against several types of cancer. However, anticancer compound of rodent tuber is currently unknown. Rodent tuber has a low genetic diversity due to conventional vegetative propagation. In vitro propagation combined with gamma-irradiation of rodent tuber’s calli had been performed to increase the genetic diversity of rodent tuber. The mutant plants had been acclimatised and analysed with RAPD molecular markers, but the phytochemical constituents of these mutants have never been investigated. This research utilised gas chromatography-mass spectrometry (GC-MS) analytical method to identify and measure the relative abundances of major phytochemical constituents of rodent tuber control and mutant plants. GC-MS analysis successfully showed phytochemical constituents of the ethanol extract of rodent tuber plants. Shoots and tubers of mutant clones had at least 8 anticancer compounds whose quantities were higher than control plants. Shoots and tubers of mutant clones also contained new anticancer compounds which were not found in control plants. Shoots of mutant clones contained new anticancer compounds such as 7-pentadecyne, β-sitosterol, hexadecanoic acid methyl ester, cis-vaccenic acid, ergost-5-en-3-ol (campesterol). Tubers of mutant clones contained new anticancer compounds such as β-sitosterol, ethyl palmitate, hexadecanoic acid ethyl ester, vitamin E (alpha tocopherol), ergost-5-en-3-ol (campesterol). Rodent tuber mutant clones are therefore very potential to be developed as anticancer drugs.

AbstractSterols, triterpenes, volatiles, polar and other constituents in aerial parts of Carthamus lanatus were analyzed by gas chromatography-mass spectrometry. Over 90 compounds were identified most of them new for the species. Sitosterol and stigmasterol were the most abundant of 10 sterols identified in the sterol fraction. Taraxasterol, α- and β-amyrine prevailed in the triterpene fraction. Volatiles, sterols and a fraction of the dichloromethane extract showed strong cytotoxicity (Artemia salina assay).

Abstract The scent gland secretions of Dumeril’s ground boa (Acrantophis dumerili), pooled from two adult males and a female, were analyzed by gas chromatography-mass spectrometry. 2-Hydroxypropanoic acid, hexadecanoic acid, as-9-octadecenoic acid, octadecanoic acid, cholesterol, and 5-cholesten-3-one were indicated. These results are compared with those obtained in analyses of the scent gland secretions of other snakes.

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.
