Starch from the seeds of Quercus leucotrichophora was isolated, purified and its physico‐chemical properties were determined. Scanning electron microscopy of the granules show that they are oval to eliptical in shape. Its has high contents of ash, lipids, proteins and lower content of amylose. Its gelatinization temperature is 80–85°C and displays high water binding capacity. It has low swelling power but high solubility. Amylograph study shows 425 B.U. paste viscosity and no thinning inspite of 3 h heating. On cooling starch retrogrades to paste viscosity of 1200 B.U.
