测定了广东产苋科6种野菜中硝酸盐、亚硝酸盐和维生素C的含量。结果表明:青葙、刺苋的硝酸盐较高、亚硝酸盐含量符合我国无公害蔬菜限量标准,维生素C含量又较为丰富,它们为品质较好的野菜;繁穗苋维生素C含量高,硝酸盐含量高,亚硝酸盐含量较低,煮熟可安全食用;空心莲子草、皱果苋和苋菜的维生素C含量较高,亚硝酸盐含量较低,但硝酸盐含量严重超标,须采取一定的措施,限量食用。
The contents of nitrate, nitrite and vitamin C in leaves of 6 edible wild vegetables of Amaranthaceae were determined.The results indicate that Celosia argentea L.and Amaranthus spinosus L. have good quality because of medium content of nitrateand nitrite, and richer content of VC; Amaranthus paniculatus L. is edible after be cooked because of higher content of of nitrate,higher content VC and lower content of nitrite; Because of the content of nitrate in the leaves of Alternanthera philoxeroides(Mart.)Griseb.,Amaranthus tricolor L.and Amaranthus viridis L. exceed the limited standard, they must be cooked and the amountmust be restricted.
