Hot water extraction technique was employed to extract the hydrocolloid from Cordia myxa leaf (PCM). The optimal conditions for extraction of PCM were determined using response surface methodology. A Box–Behnken design (BBD) was applied to evaluate the effects of three independent variables (extraction time (X1: 1–4 h), extraction temperature (X2: 55–95 °C), and water to raw material ratio (X3: 5–30 ml/g) on the extraction yield of PCM. The content of moisture, water-soluble and water-insoluble ash, crude protein and total phenol were determined in the extracted hydrocolloid by standard methods. The maximum hydrocolloid extraction yield (9.501 ± 0.15%) was achieved by using extraction time of 4.94 h, extraction temperature of 94.91 °C and water to raw material ratio of 21.74 ml/g. The contents of moisture, crude protein, water-soluble and water-insoluble ash and total phenol were 21.63 ± 0.94%, 14.27 ± 0.55%, 3.07 ± 0.16% and 2.61 ± 0.19 mg galic acid/g, respectively.
