In this paper, the ultrasonic extraction method of Oligomeric Proantho Cyanidin with chestnut shells as raw materials is studied. Using single factor method we study the effects of different extraction time, extraction reagent, extracting agent concentration and ultrasonic power on the extraction rate of Oligomeric Proantho Cyanidin. After analyzing these various factors, we make the orthogonal experiment with the factors including extraction time, extraction agent concentration, extraction temperature, solid-liquid ration, and get the optimal conditions. The experimental results show that the optimum extraction conditions are as follow: time of 30 min, extracting agent of 40% (v %) ethanol aqueous solution, extraction temperature of 40 °C, solid-liquid ratio of 1: 25 g/mL and ultrasonic power of 100 w; under these conditions the extraction rate of Oligomeric Proantho Cyanidin is 3.418%.

Pectin was extracted from Ramie [Boehmeria nivea (L.) Gaud] through ammonium oxalate extraction method. The influences of single factors (ammonium oxalate concentration, extraction time, solid–liquid ratio, and reaction temperature) on the yield of ramie pectin were studied. Orthogonal experiment was then performed to optimize the combination of the given conditions using pectin yield as the measuring indicator. Finally, the partial physicochemical properties of ramie pectin extracted in the optimal conditions were analyzed. Results showed that the optimal conditions for single-element experiment were 3.5 h (extraction time), 1:25 (solid–liquid ratio), 0.85% (concentration of ammonium oxalate) and 95 °C (extraction temperature), and that the optimal combination conditions for orthogonal experiment was 4 h, 1:30, 0.95% and 90 °C. The ramie pectin yield extracted in optimal conditions reached 15.81%, and its protein content, galacturonic acid content, and esterification degree were 0.659 mg/g, 49.92%, and 53.11%, respectively. Therefore, the proposed method was successfully applied to obtain ramie pectin and may provide scientific basis for improving the multi-utilization value of ramie.
