Abstract
Achyranthes coynei is a rare, endemic perennial shrub reported from Karnataka and Maharashtra states of India. The
plant is used to treat various disorders by folk healers and was proven to have antimicrobial and antioxidant properties.
The present study was undertaken to evaluate microscopic and macroscopic characters of A. coynei stem, along with its
physicochemical parameters. ProgRes® CapturePro and Microsoft Excel were used for statistical analysis. Perennial, shrubby
nature and woody stem were the distinguishing morphological characters observed. Transverse section (TS) illustrated
quadrangular outline of the stem and showed the presence of two types of trichomes on the thick‑walled epidermis. TS
also showed number of rosette calcium oxalates crystals; prismatic and microsphenoid crystals; conjoint, collateral open
secondary vascular bundles; and two amphixylic medullary bundles in the pith. Ash and extractive values, micro and macro
elements and nutritive factors were estimated in the present study. The presence of alkaloids, saponins and triterpenoids
were observed in preliminary phytochemical screening. High‑performance thin layer chromatographic analysis yielded
different bands and also indicated the presence of oleanolic acid. The studied parameters for A. coynei stem will be useful
for identification and authentication of the plant material.
