Abstract
The present study focuses on the pharmacognostic evaluation of Polianthes
tuberosa Linn. (Family: Agavaceae), an aromatic perennial herb widely
utilized for its therapeutic and commercial value. The plant was collected from
the Madurai region, Tamil Nadu, and authenticated for further examination.
Pharmacognostic studies, including macroscopic, microscopic, and powder
analyses, were performed according to WHO guidelines for quality control and
standardization. Macroscopic evaluation revealed characteristic milky-white,
tubular, waxy flowers with a strong sweet fragrance. Microscopic analysis of
the floral parts (petals, ovary, and stamens) showed diagnostic features such
as uniseriate epidermis, parenchymatous mesophyll, vascular bundles, osmophore
cells, and tricolpate pollen grains. Powder microscopy confirmed the presence
of parenchyma cells, pollen grains, and fibrous elements. These pharmacognostic
parameters provide key diagnostic characters for the identification and
authentication of P. tuberosa, ensuring purity and preventing
adulteration in herbal formulations. The study establishes baseline data
supporting further phytochemical and pharmacological investigations of this
medicinally significant plant.
