Pharmacognostic studies of leaf of Hyptis suaveolens L.
by Jelani S., Prabhakar M. (1991)
Abstract
This paper deals with the pharmacognosy of Hyptis suaveolens leaf including its morphological, anatomical, chemical constituents and powder analysis.
Contrary to earlier reports, the leaves are amphistomatic.
Stomata are diacytic, a few being isotricytic and ansiotricytic.
Four types of trichomes have been noted. The venation is semicraspidodromous. Midrib consists of one large moon shaped and petiole with four wedge-shaped vascular bundles. Powder microscopy revealed fragments of epidermis, mesophyll, trichomes and tracheary elements. Positive tests for glycosides, polyphenolases, flavones and juglones are also recorded.
