[Objectiv The aim is to study the extraction technology of melanin from banana peel, and discuss its stability. [Metho We used banana peel as raw material, the absorbance at 410 nm as the index, extracted melanin by base-acid method, and optimized the extraction technology by the single factor and orthogonal test. Then we discussed the melanins stability at different temperature, light source, pH value, metal ions, antioxidant and reducing agents.[Result The best extraction conditions of melanin is that, hydrochloric acid soak time 5 h, alkaline solution pH value 14, extracting time 20 min, extraction temperature 70 °C, absorbance value about 0.309 A. Melanin from banana peel is stable at high temperature, different light source irradiation, reducing agent coexist; but at room temperature, metal ions and oxidizing agent coexist, it is unstable. [Conclusio This study provided experimental basis for the optimization and development of melanin from banana peel.

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.

Using ultrasonic-extraction technology, the condition of extracting the active compounds-flavonoids and rosmarinic acid ofPerillawas studied. The effects of four main factors include ultrasonic power, temperature, time and solid-liquid ratio on the extraction-rate of the flavonoids and the rosmarinic acid ofPerillawere reviewed by single factor experiments,and the flavonoids and the rosmarinic acid was determined by NaNO2-Al (NO3)3-NaOH method and FeSO4method. On the base of single factor experiments, the extraction technique was optimized in the orthogonal test. The result showed that temperature was the most important factor in the influencing factors on the extraction-rate. The subsequence of importance was temperature > time > solid-liquid ratio > ultrasonic. The optimal extraction conditions were: extraction solvent 3%borax, solid-liquid ratio 1:50(w/v), ultrasonic power 300W, time 90min , temperature 75°C. Under the optimum technological conditions, 34.64mg/g of flavonoids and rosmarinic acid fromPerillacould be obtained.
