Abstract

Rosmarinic acid (RA) was extracted and determined from Ocimum basilicum, Origanum majorana, Salvia officinalis, Rosmarinus officinalis and Thymus vulgaris. R. officinalis expressed the highest content (186.4 mg/DW) followed by O. majorana (140 mg/DW). However, O. basilicum and T. vulgaris and S. officinalis showed 80.7 mg/DW, 66.7 mg/DW, and 50.4 mg/DW of RA, respectively. Treatment of O. majorana seedlings with the various seaweed extract from J. rubens, C. prolifera and C. sinuosa increased RA content with 7.7%, 21.6% and 50% , respectively. RA from O. majorana exhibited appreciable antioxidant activity using DPPH and ABTS compared to ascorbate as standard antioxidant
