Abstract

Folate (vitamin B9) content was evaluated in 10 varieties of coriander with the aim of enhancing its concentration and stability, because of three reasons: 1) coriander is among a few widely used greens in the world and suits many cuisines, 2) folate deficiency is prevalent in developing countries causing anaemia, infant mortality and neural tube closure defects, and 3) natural folate is preferred due to doubts about health risks associated with the synthetic form. In C. sativum, the highest folate content of 1,577 μg/100 g DW was found in var. GS4 Multicut foliage of mature plants (marketable stage) with an insignificantly higher content (1,599.74 μg/ 100 g DW) at flowering, which is a stage not preferred in markets. In callus cultures treated with plant growth regulators (GRs) (6-benzylaminopurine, kinetin and abscisic acid) substantial increase in folate occurred after 6 h, whereas elicitors (methyl jasmonate and salicylic acid) caused rapid 2-fold increase of folate, particularly in response to salicylic acid. Based on these observations, foliar applications were done for in vivo plants, where salicylic acid (250 μM, 24 h) also enhanced folate level by 2-folds (3,112.33 μg/100 g DW), although the content varied with diurnal rhythms. Stability of folates in treated coriander foliage was 10 % higher than in untreated foliagewhen stored at 25 °C and 4 °C. This study has established for the first time that coriander foliage is rich in folates, which can be doubled by elicitation and impart 10 % more stability than control during processing and storage.
