This study aimed to assess the leaf aqueous extract composition of Erythrina crista-galli and the effects of its inclusion on the diet of red-eye tetra (Moenkhausia forestii), concerning enzyme content of digestive, hepatic, and oxidation metabolism and pigmentation. Fish (1.78 ± 0.54 g) were divided into groups: fasting (without feeding), control (commercial feed), and treatment (commercial feed with leaf aqueous extract of E. crista-galli) and feeding apparent satiety for 21 days, in the extracted analysis by mass spectrometry, phenolic compost, and flavonoids. The agitation degree and number of dashes, in all supplemented treatments, were lower than those in the control diet when fed for 7 or 15 days. In the digestive enzymatic activity did not differ (p > 0.05). The hepatoprotective treatment group showed lower alanine aminotransferase (ALT) and higher levels of antioxidant catalase (CAT). The results indicated that the aqueous leaf extract of Erythrina crista-galli assists in function maintenance of the liver; and stimulates CAT in red-eye tetra, suggesting that the identified compounds act on the liver and skin, showing hepatoprotective effects and stimulating tranquility.
本研究旨在评估鸡冠刺桐叶的水提物成分，并研究其对红眼四间鱼（Moenkhausia forestii）饮食的影响，包括消化、肝脏和氧化代谢以及色素沉着相关的酶含量。将鱼（1.78±0.54g）分为三组：禁食组（不投喂）、对照组（商业饲料）和处理组（商业饲料添加鸡冠刺桐叶的水提物），并进行为期 21 天的摄食实验，采用质谱分析法、酚类化合物和类黄酮对饲料进行提取分析。在所有添加处理组中，与对照组相比，在投喂 7 天或 15 天后，鱼的游动幅度和冲刺次数都较低。消化酶活性没有差异（p＞0.05）。具有保肝作用的处理组丙氨酸转氨酶（ALT）较低，而抗氧化酶过氧化氢酶（CAT）水平较高。结果表明，鸡冠刺桐叶的水提物有助于维持肝脏功能，并刺激红眼四间鱼的 CAT，这表明鉴定出的化合物作用于肝脏和皮肤，具有保肝作用和镇静作用。
