Dhanyaka (Coriandrum sativum) Description:

dhanyaka (coriandrum sativum)a) Macroscopic: Coriandrum sativum fruit is rounded, mericarps usually united by their margins forming a cremocarp of about 2-4 mm in diameter. It is uniformly brownish-yellow, glabrous, sometimes crowned by the remains of sepals and styles. The primary ridges are 10, wavy and slightly inconspicuous, and secondary peaks are 8, straight, more prominent, endosperm coelospermous, odor, and aromatic, taste, spicy and characteristic.

b) Microscopic: The transverse section of fruit shows a pericarp with an outer epidermis and has a slightly thickened anticlinal wall. The mesocarp parenchymatous outer layer has inner cells in wavy longitudinal rows and has degenerated vittae as tangentially flattened cavities. The middle layer of mesocarp sclerenchymatous forms a thick layer of fusiform, sinuous rows with pitted cells. Its layer often crosses at right angles with definite longitudinal strands in the secondary ridges.

The inner cells of the mesocarp are large, hexagonal, and having lignified walls. The inner epidermis of very narrow thin-walled cells is slightly sinuous anticlinal walls showing parquetry. Each side of each mesocarp contains volatile oil, the endosperm of thick-walled cellulosic parenchyma having fixed oil, multiple aleurone grains, having about 4-8 in diameter containing micro-rosettes of calcium oxalate. The split carpophores pass at the apex of each mericarp into raphe, adjacent to the inner side, consisting of fibers surrounded by spiral vessels.
