PHYTOCHEMICAL SCREENING AND TLC FINGERPRINTING OF VARIOUS EXTRACTS OF ROOTS AND RHIZOMES OF COLLINSONIA CANADENSIS

Collinsonia canadensis is a perennial medicinal herb in the mint family. Common names include Canada Horsebalm, Richweed, Hardhack, Heal-All, Horseweed, Ox-Balm and Stoneroot. Traditionally the roots and rhizomes of the plant are used for various diseases. The present study deals with phytochemical screening and thin layer chromatographic (TLC) fingerprinting of (petroleum ether, chloroform and methanol extracts) Collinsonia canadensis roots and rhizomes. In phytochemical screening maximum diversity of chemical constituents were found in methanol extract of roots and rhizomes of Collinsonia canadensis. Thin layer chromatographic (TLC) fingerprinting studies showed that all the three extracts i.e petroleum ether, chloroform and methanol extracts of roots and rhizomes of Collinsonia canadensis contains phytochemical components which were determined by Rf ( Retention factor ) values.
