Coriander Seed ( ధనియాలు ) like many spices, contains phytochemicals which may delay or prevent the spoilage of food seasoned with this spice. The nutritional profile of coriander seeds is different from the fresh stems and leaves. Leaves are particularly rich in vitamin A, vitamin C and vitamin K, with moderate content of dietary minerals (table above). Although seeds generally have lower content of vitamins, they do provide significant amounts of dietary fiber, calcium, selenium, iron, magnesium and manganese.
