Pharmacognostic study and phytochemical investigation of Plectranthus hadiensis var. tomentosus (Benth. ex E. Mey.) Codd, họ Lamiaceae)

Abstract

Plectranthus hadiensis var. tomentosus (Benth. ex E. Mey.) Codd (PHT) is a member of the Plectranthus genus, Lamiaceae family. PHT found in South Africa occurs naturally throughout the tropical and warm regions. In Vietnam, PHT is an alien plant and is cultivated mainly as an indoor plant. Until now, there has been no research on this plant.  Herein, the morphology and microscopy of Vietnamese PHT was studied in detail, and thereby, identified as the preliminary phytochemical study that proved the occurrence of terpenoid, flavonoid, and saponin. These results may serve as initial basis for botanical identity tests in material quality control and further phytochemistry studies of the plant.
