| Abstract (English): |
Nineteen varieties of celeries, including Green stalk celery, White celery, Purple celery, etc. were taken as research materials. Water extracts of the edible parts (stems and leaves) of the celeries investigated were prepared under the same conditions (1: 30 g·mL-1 in solid-liquid ratio, 2h in extraction time and 60 °C in extraction temperature) to screen out the varieties and their edible parts with higher in vitro angiotensin converting enzyme (ACE) inhibitory activity, total phenols and total flavonoids contents. The results indicated that in vitro ACE inhibitory activities of celery leaves extracted with water were significantly higher than those with ethanol solution (P < 0. 05). The in vitro ACE inhibitory activities in leaf aqueous extracts of different celery varieties concentrated in 80% - 100% ; total flavonoids contents were focused on 200 - 250 mg·L-1, with highest in White-stalk celery leaf and lowest in White celery leaf; total polyphenols contents were focused on 130 -150 mg·L-1, with highest in Purple celery leaf and lowest in Hollow stalk green celery. Correlation analysis indicated that in vitro ACE inhibitory activity was positively related with both of total flavonoids content and total polyphenols content, with their correlation coefficients being 0. 3 -0. 6. Green stalk celery leaf had the lowest half inhibitory concentration (IC50) values of ACE (1. 258 mg·mL-1), followed by Four season celery (1. 368 mg·mL-1) and White celery leaf (1. 829 mg·mL-1) .

| Abstract (Chinese): |
以青梗芹菜、白芹菜、紫芹等 19 个品种芹菜为研究对象, 在相同条件 [料液比 1:30 (g·mL-1)、时间 2h、温度 60 ℃] 下提取得到可食用部分 (茎和叶) 的水提取液, 用于筛选具较高体外血管紧张素转换酶 (ACE) 抑制活性、总酚和总黄酮含量的芹菜品种及其部位.结果表明, 芹菜叶水提物的体外 ACE 抑制活性显著 (P<0.05) 高于乙醇溶液提取物; 不同品种芹菜叶水提物的体外 ACE 抑制活性集中在 80％ ～100％; 总黄酮含量集中在 200～250 mg·L-1, 白梗芹菜叶中含量最高, 白芹叶中含量最低;总酚含量集中在 130～150 mg·L-1, 紫芹叶中含量最高, 空杆绿芹叶中含量最低.相关性分析表明, 芹菜叶的体外 ACE 抑制活性与其总酚和总黄酮含量均呈正相关, 其相关系数均在 0.3～0.6. 体外 ACE 半抑制浓度 (IC50) 表明, 青梗芹菜叶水提物的 IC50 最低 (1.258 mg·mL-1), 其次为四季慢芹菜叶和白芹菜叶, 分别为 1.368 mg·mL-1 和 1.829 mg·mL-1.
