    摘要:

    采用水浴振蕩,、超聲,、微波和超聲—微波協(xié)同對丁香抗氧化活性物質進行了提取，并用人工胃,、腸液對有效部位進行了處理,。結果表明，在4種提取方法中,，協(xié)同提取和微波提取總多酚,、總黃酮得率以及抗氧化能力要優(yōu)于另外2種方法，協(xié)同提取時間僅為微波提取的1/2,，協(xié)同提取效率最高,。人工胃液處理后，丁香有效部位抗氧化活性得到顯著提高（P<0.001）,，而人工腸液處理后,，其抗氧化活性卻顯著性降低（P<0.001）。

    Abstract:

    The antioxidants of clove were extracted by water bath shaking, ultrasonic-assisted extraction (UAE), microwave-assisted extraction (MAE) and ultrasonic and microwave-assisted extraction (UMAE), the effective fraction of clove were immersed in the artificial gastrointestinal juice. The results showed that the total polyphenols and flavonoids recoveries were highest, and the antioxidant capacities were strongest for the extracted liquids by MAE and UMAE. However, the extraction time of UMAE was only half of that of MAE. The extraction efficiency of UMAE was the highest. The antioxidant capacities of the effective fraction of clove were significantly improved after immersed by the artificial gastric juice (P<0.001), while its antioxidant capacities were significantly reduced after immersed by the artificial intestinal juice (P<0.001).
