摘　　要：采集了江苏省主要栽培的8个水芹地方品种的食用器官,分析比较部分营养品质成分的含量及其差异,结果表明:不同品种间食用器官的干物率介于5.69%～9.74%、可溶性总糖含量介于8.55～25.11mg·g-1(FW)、粗纤维含量介于2.61～5.02mg·g-1(FW)、总膳食纤维含量介于29.11～51.05mg·g-1(FW);食用器官干物质的持水力介于444%～1049%、膨胀力介于9.44～17.53mL·g-1,其对铅、镉离子的最大束缚量分别介于242.91～369.16mg·g-1和274.51～346.64mg·g-1、最小束缚浓度分别介于0.02～0.09mmol·L-1和0.01～0.03mmol·L-1,认为水芹是一种优良的膳食纤维类蔬菜。Eight cultivars of water dropwort〔Oenanthe javanica （Bl.） DC.,O.stolonifera （Roxb） wall.〕were collected in main production areas of Jiangsu Province.Contents of some nutrient and quality components of edible parts were tested.The results showed that the dry matter rate among all cultivars were 5.69 %-9.74 %,the contents of total soluble sugar were 8.55-25.11 mg·g-1 （FW） and those of crude fiber were 2.61-5.02 mg·g-1 （FW） ,while those of total dietary fiber were 29.11-51.05 mg·g-1 （FW） .The water holding capacity and expansive capacity of dry matter of edible parts were 444 %-1 049 % and 9.44-17.53 mL·g-1,respectively.And the maximum bounding quantity to Pb2＋ and Cd2＋ were 242.91-369.16 mg·g-1 and 274.51-346.64 mg·g-1,respectively.The minimum bounding concentration to Pb2＋ and Cd2＋ were 0.02-0.09 mmol·L-1 and 0.01-0.03 mmol·L-1,respectively.We conclude that water dropwort is a kind of vegetable with rich of dietary fiber.
