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.

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.
