Spray drying of Tinospora cordifolia leaf and stem extract and evaluation of antioxidant activity.

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.
