Phytochemical screening of plant extracts and GC-MS analysis of the n-hexane extracts of stems and roots of Catharanthus roseus growing in Bangladesh

Phytochemical screening and gas chromatography-mass spectrometry (GC-MS) methods were used to determine the phytochemical components of various extracts stems roots Catharanthus roseus. Preliminary n-hexane, chloroform, ethyl acetate methanol roseus carried out identify class compounds present in each extract. The results exhibited that steroids, terpenoids, flavonoids phenolic found every extract roots. Alkaloids also all except n-hexane. But carbohydrates absent methanol. GC-MS analysis n-hexane was done, which allowed identification quantification 30 22 soluble roots, respectively. In this experiments, D:B-Friedo-B':A'-neogammacer-5-en-3β-ol (10.23%) Ethyl palmitate (13.63%) identified with highest concentration
