Oroxylum indicum is a widely used multipurpose tree with its medicinal importance recognized by Ayurveda for centuries, as almost all parts of this tree possess medicinal value. Extracts of root and stem bark have antimicrobial, antifungal, anti-inflammatory and anti-cancerous properties. The high demand for this medi­cinal plant has caused a gradual depletion of the species from its natural habitat. The present study has been carried out to assess the distribution and mapping for the selection of elite germplasms on the basis of princi­pal active constituents in different forest divisions of Punjab, India. The analysis led to the selection of three samples having a higher percentage of oroxylin-A, baica­lein and chrysin. The three screened-out germplasms are recommended for conservation and multiplication to produce quality planting stock.

Abstract


Oroxylum indicum is a widely used multipurpose tree with its medicinal importance recognized by Ayurveda for centuries, as almost all parts of this tree possess medicinal value. Extracts of root and stem bark have antimicrobial, antifungal, anti-inflammatory and anti-cancerous properties. The high demand for this medi­cinal plant has caused a gradual depletion of the species from its natural habitat. The present study has been carried out to assess the distribution and mapping for the selection of elite germplasms on the basis of princi­pal active constituents in different forest divisions of Punjab, India. The analysis led to the selection of three samples having a higher percentage of oroxylin-A, baica­lein and chrysin. The three screened-out germplasms are recommended for conservation and multiplication to produce quality planting stock.
