Quantitative Phytochemical Screening and GC-MS Analysis of the Ethanolic Extract of Tabebuia roseo-alba (Ridl) Sand

Medicinal plants have been used in folkloric medicine to treat various ailments. The compound investigations of medicinal plants have largely been driven to discover new drugs to treat human diseases. The study was designed to estimate the amount of phytochemical constituents and also to explore the presence of bioactive compounds in ethanolic extract of Tabebuia roseo-alba using Gas Chromatography-Mass Spectrometry (GC-MS). Quantitative phytochemical analysis was carried out by standard procedures. GC-MS analysis of the plant extracts was performed by using GC SHIMADZU QP2010 system and Gas Chromatograph interfaced to a Mass Spectrometer (GC-MS) equipped with RXi -1ms fused silica capillary column. The total phenol content was found to be 112.67+0.03 in ethanolic extract of Tabebuia roseo-alba leaves. The GC-MS analysis revealed the presence of eight major peaks from which various bioactive compounds were ascertained. In conclusion, ethanolic extract of Tabebuia roseo-alba possess many bioactive constituents which may be accountable for its various pharmacological activities.
