title: The genus Plectranthus in India and its chemistry.
abstract: Phytochemical constituents isolated from Indian species of the genus Plectranthus reported up to 2009 are compiled. In India, the genus Plectranthus is found in all the habitats and altitudes, particularly in the Himalaya, the Southern Ghats, and the Nilgiri region. P. amboinicus, P. barbatus, P. caninus, P. mollis, P. coetsa, and P. incanus are the most common species found in India. Phytochemical studies of the genus revealed that Indian Plectranthus species are rich in essential oil, and that the most abundant secondary metabolites are diterpenoids, i.e., labdanes, abietanes, and ent-kauranes, as well as triterpenoids.
