Abstract 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.
