Abstract
Antioxidants possess the ability to protect the body from damage caused by free radical
induced oxidative stress and have antiageing property. ‘Theinga Dara Thanhitar’ book, written by
Ashin Nagathein described that ‘Rasayana and Triphala’ drugs have the ability to prevent ageing
and illness. This study was carried out to investigate the antioxidant activities of commonly used
ingredients of ‘Rasayana’ such as Streblus asper Lour. (Okhne), Cassia fistula Linn. (Ngu), Tinospora
cordifolia Miers. (Sindone-Ma-Nwe), Asparagus racemosus Willd. (Shin-Matet), Boerhavia
diffusa Linn. (Payan-Nawa), and ‘Triphala’ such as Phyllanthus emblica Linn. (Ze-Phyu), Terminalia
chebula Retz. (Phan-Ga) and Terminalia belerica Roxb. (Thit-Saint). Their absorbances were
evaluated using 1,1-diphenyl -2-picrylhydrazyl (DPPH) assay method by using spectrophotometer.
Yield percents of these plants were ranging from 4.05% to 28.6%. The watery extracts of Okhne,
Ngu, stem of Sindone-Ma-Nwe, tubor of Payan-Nawa, Ze-Phyu, Phan-Ga, and Thit-Saint contain
phenols and tannins which have free radical scavenging activities. It was found that the bark and
stem of Okhne, tubor of Payan-Nawa and ‘Triphala’ had the least IC50 value i.e. the best antioxidant
potency. Therefore, the findings from this study supported the experience-based findings of antiageing
activities in ‘Triphala’ and ‘Rasayana’ to be evidence-based.
