本课题以西印度樱桃冻干粉为研究对象，研究了西印度樱桃冻干粉的提取工艺，确定最佳料液比、提取时间、温度、提取液中主要成分，并对提取液进行脱盐处理；对提取液的抗氧化功效、美白功效以及刺激性进行了研究；并最终形成提取液中还原型维生素C相对稳定体系。

In the hydroxylation of phenol with H〓O〓 in the presence of Ti-ZSM-5, water is best solvent. It produces catechol and hydroquinone simultaneously, and catechol/hydroquinone ratio is approximately 0.85. The results show H〓O〓 utilization ratio increase 14%, when nonoxidizable weak acid HAc is added into the reaction system. Under the conditions of Ti-ZSM-5 as catalyst, phenol/H〓O〓 ratio being 10, a little HAc, temperature 75℃, reaction time 6h, H〓O〓 utilization ratio reaches 74. 6mo1% in the reaction.

对Ti-ZSM-5催化苯酚羟基化的研究结果表明，水是最好的溶剂，羟基化有邻、对苯二酚两种产物，并且邻苯二酚/对苯二酚摩尔比可维持在～0.85左右；向反应体系中加入非氧化性弱酸性助剂HAc时，H〓O〓有效利用率较未加入助剂时可提高14mol%；当催化剂用量为8g/100g苯酚、苯酚/H〓O〓比为10、反应温度75℃、添加少量HAc的条件下，反应6h后，H〓O〓有效利用率可达74.6mol%。
