Abstract

Foliage of Coriandrum sativum is a rich source of natural folates amenable for enhancement through salicylic acid-mediated elicitation, thereby holding a great promise for natural-mode alleviation of this vitamin (B9) deficiency. In the present study we report salicylic acid-mediated differential elicitation of different forms of folates – 5-methyltetrahydrofolate, 5-formyltetrahydrofolate and 10-formyltetrahydrofolate – their stabilities during microwave-drying and bioaccessibilities from fresh and dried foliage. The first two compounds nearly doubled and the third increased sixfold post-elicitation, with all three showing concomitant increase in bioaccessibilities. Although a slight decrease in bioaccessibility was observed in dried foliage, over twofold increase of each form of folate upon elicitation would deliver much higher levels of natural folates from this traditional culinary foliage, which is widely used in many cuisines. Elicitor-mediated folate enhancement also imparted reduction of oxidative status and the enhancement of antioxidant enzyme activities in coriander foliage.
