Macro-microscopic standards of an abortifacient druglangali (tubers of Gloriosa superba Linn.)

Abstract

Gloriosa superba Linn., a striking herbaceous tendril climber with underground cylindrical white tuberous root, forms as a source of Langali -a upavisha dravya. The root contains an alkaloid colchicine (0.23- 0.3%). Though a poisonous root, having the magnificent therapeutic benefit, deliberate attempt to record its standard macro-microscopic features by photomicrography is lacking. Matured, authenticated tuberous roots were collected from its natural habitat. Macro-microscopic and powder characters were recorded using standard methodology. Thin walled parenchymatous cells with plenty of simple and compound starch grains, collateral vascular bundles scattered in the ground tissue, and absence of any sclerenchymatous tissue are microscopic recordings of transverse section of root. The powder has shown the presence of starch grains and cells of scaly leaves in surface view. This study along with photographic atlas will serve as reference for the correct identification of the drug and to differentiate it from their substitute and adulterants.
