Abstract

Tinospora cordifolia (Guduchi) is widely used in folk medicine/ ayurvedic system of medicine, also in ayurvedic ‘Rasayanas’ to improve the immune system and used as general tonic, anti-periodic, anti-spasmodic, antiinflammatory, anti-arthritic and anti-diabetic agent. Numerous studies have been reported on the health benefits of individual parts or whole Guduchi plant. However, most of the work has focused on the extracts of T. cordifolia. In this study, T. cordifolia leaf and stem extract powders were prepared using spray drying at 90 °C outlet temperature of the spray dryer. The powder morphology has also been studied by scanning electron microscopy. The antioxidant activity was followed by DPPH method. The leaf extract powder showed higher retention of antioxidant activity than stem extract powder.
