采用HPLC法从珍珠红14、粤油114、汕油523和湛油75等4个品种花生的废弃物中提取白藜芦醇和白藜芦醇苷，并进行定性与定量分析，根据提取物的HPLC出峰时间及与对照品的相加试验，在4个花生品种的不同器官中均鉴定出了白藜芦醇和白藜芦醇苷.不同花生品种和同一品种不同器官中2种活性物质的含量差异很大；在珍珠红14的各器官中含量最高，湛油75中含量最低.各品种花生根中2种化合物的含量最高.珍珠红14的根、茎、叶和果壳中白藜芦醇含量分别为148.7、33.3、23.1和9.4 g/g，白藜芦醇苷含量分别为133.7，37.7，27.7和11.5 g/g.珍珠红14根中白藜芦醇和白藜芦醇苷含量大大高于葡萄和桑椹等材料.本研究为花生废弃物的综合利用提供了依据.
Large amount of plant waste materials (root, stem, leaf and fruit shell) are produced in peanut (Arachis hypogaea) cultivation and processing. We investigated the extraction, identification and contents of resveratrol and polydatin in different organ wastes of four varieties of peanut (Arachis hypogaea), Pearl Red 14, Guangdong Oil 114, Santou Oil 523 and Zhanjian Oil 75. The optimal extraction is that dried material was crushed and sieved through a 40 mesh sieve, ultrasonic-extracted with 60% ethanol for 3 times. Contents of the bioactive substances were analyzed by HPLC. Both resverstrol and polydatin were identified in all root, stem, leaf and fruit shell of the four varieties of peanut. The contents of the two compounds varied greatly in different peanut varieties and organs, with the highest contents for both compounds in Pearl Red 14, and the lowest in Cham oil 75. The root of all varieties contained much higher resveratrol and polyatin than other organs. Resveratrol contents were 148.7, 33.3, 23.1 and 9.4 g/g, and polyatin contents were 133.7, 37.7, 27.7 and 11.5 g /g in Pearl Red 14 roots, stems, leaves and shell, respectively. The contents of both resveratrol and polydatin in Pearl Red 14 root are much higher than in grapes, mulberries and other plant materials. The work provides useful information for comprehensive utilization of peanut wastes.
