Kiwi fruit samples ( Planch, cv. Hayward) represent a suitable and good source for fibers obtainment as well as for polyphenolic and carotenoid extraction. With this aim, in this study they were submitted to a double phase extraction to separate insoluble fibers by an organic phase containing lipophilic substances and an hydroalcoholic phase containing polyphenols and soluble fibers. Insoluble fibers could be separated by filtration and sent to be micronized and reused. Hydroalcoholic fractions were then furtherly fractionated by solid-phase extraction. Data coming from the color CIELab* and the HPLC-DAD analyses of the extracts were compared and correlate with those coming from the SPME-GC/MS analysis of either the finely shredded peels or of the extracts. The obtained extracts were also submitted to anti-radical activity evaluation and anti- activity. Results show that all of the obtained residues are value added products. Hypotheses were also made about the nature and the possible recycle of the obtained purified solid residue.
奇异果样品（猕猴桃科，品种海沃德）是获取纤维以及提取多酚和类胡萝卜素的合适且优质来源。出于这个目的，在本研究中，将它们进行双相萃取，通过含有亲脂性物质的有机相和含有多酚及可溶性纤维的水醇相来分离不溶性纤维。不溶性纤维可通过过滤分离出来，送去进行微粉化处理并再利用。然后，水醇级分通过固相萃取进一步分级。将提取物的颜色CIELab*数据和HPLC-DAD分析数据与来自精细切碎果皮或提取物的SPME-GC/MS分析数据进行比较并关联。所获得的提取物还进行了抗自由基活性评估和抗氧化活性评估。结果表明，所有获得的残渣都是增值产品。还对所获得的纯化固体残渣的性质和可能的再循环提出了假设。
