GC-MS ANALYSIS OF CHEMICAL COMPONENTS OF TWO DIFFERENT STAGES OF ROOT PART OF MOOLAK (RAPHANUS SATIVUS LINN.)

Abstract

Moolak or Radish (Raphanus sativus Linn.) is grown all over the world. Radish is eaten raw as salad due to its pungent flavor. Tender radish root is consumed with leafy vegetable and radish in its starting stage of bolting is consumed as stew. After late bolting stage, only new leaves produced in inflorescence axis and seeds are consumed as edible substance and mature seeds are used for medicinal purpose like Kushtha (Skin disease). Formulations of Moolak seed is already mentioned in Ayurvedic literatures. Here we are taking tender and early bolt stage of radish where tender is balmoolak and Bolt is vriddha moolak. This study shows the differences in chemical composition of two stages of moolak to know about their medicinal properties, because medicinal properties of herbs are due to phytoconstituents. GC-MS (Gas chromatography - mass spectrometry) technique is used to identify bioactive compounds in methanolic extract of Raphanus sativus. Tender radish (balmoolak) has shown total 38 peaks and Bolt radish (vriddha-moolak) showed total 41 peaks of phytoconstituents. 15 compounds are common among both samples.
