The physico‐chemical properties of starch isolated from Coleus tuber ( Coleus parviflorus ) has been investigated. The yield of extracted starch is 14.4% from the raw tuber. The starch behaves like a cereal starch. The granules are 2.5–17.5 um in diameter and show “A” pattern on X‐ray diffraction. The starch exhibits limited two stage swelling and rapid dissolution in DMSO. It has an iodine affinity of 3.63, and the amylose content is 18.18%. The paste viscosity was stable during cooking and has a positive set back unlike cassava starch. The starch was somewhat resistant to amylase attack.
