Hawk tea (HT), made from the leaves of Litsea coreana Levl. var. lanuginosa, is a traditional Chinese herbal tea. Different processing methods alter the chemical composition of the HT, which changes the sensory qualities and pharmacological properties. The chemical composition, sensory qualities, antioxidant activities, and potential hepatoprotection (ameliorating acute alcoholic liver damage using a mouse model) of pan-fried (PFHT), sun-dried (SDHT), and fermented hawk tea (FHT) were investigated. PFHT had the highest level of phenolics and flavonoids, followed by SDHT and FHT. The highest levels of total and floral/fruit-like volatiles were observed in FHT, which had the highest overall sensory acceptance using a consumer panel. The PFHT and SDHT showed stronger antioxidant activity than FHT. The HT aqueous extracts showed similar hepatoprotective effects in the mouse model, among which PFHT aqueous extracts were the most effective in suppressing hepatic steatosis. PFHT showed the highest health-promoting value with the highest yield of aqueous extracts and the best protective effects against alcoholic liver damage.

鹰茶（HT），由Litsea coreana Levl的叶子制成。变种 拉努吉诺萨，是传统的中草药茶。不同的加工方法会改变HT的化学成分，从而改变感官品质和药理特性。研究了煎炸（PFHT），晒干（SDHT）和发酵鹰茶（FHT）的化学成分，感官品质，抗氧化活性和潜在的肝保护作用（使用小鼠模型减轻急性酒精性肝损伤）。PFHT的酚类和类黄酮含量最高，其次是SDHT和FHT。在FHT中观察到最高水平的总挥发物和类似水果/水果的挥发物，而使用消费者调查小组的总体感觉接受度最高。PFHT和SDHT的抗氧化活性比FHT强。HT水提取物在小鼠模型中显示出相似的肝保护作用，其中PFHT水提取物在抑制肝脂肪变性方面最有效。PFHT具有最高的健康促进价值，水提取物的收率最高，并且对酒精性肝损害的保护作用最佳。
