| Abstract: | In literature, the vernacular name Ratanjot is attributed to at least 15 plant species of
four different families. Taxonomic analysis revealed that true Ratanjot comprises of the crude
rootstocks of the plant Arnebia nobilis Reichb.f. Interestingly, this material, though abundantly
available in India, is not indigenous to this country but imported from Afghanistan. Macroscopic
analysis of authenticated sample showed the material to be in the form of purple brown roots which
are fusiform, twisted, covered with papery layers and have a pungent odour. Under SEM, the adaxial
surface showed the presence of epidermal cells with stomata and epicuticular wax secretions whereas,
abaxial surface showed only elongated epidermal cells. The powdered roots gave orangish brown
colour with concentrated nitric acid and bright red colour with acetic acid during chemical
identification. TLC analysis of the n-hexane extract showed the presence of five red and pink
components. Shikonin was identified as one of the components; however, it is not the major component. |
