| Abstract: In order to fully exploit the wild vegetable resources, the nutrition components of twelve common wild vegetables growing in Tianshui city, such as Zanthoxylum bungeanum leaves, Aralia chinensis buds, Capsella bursa-pastoris, Allium macrostemon, Carum carvi, Phragmites australis, Acanthopanax senticosus, Toonasinensis, Medicago sativa, Artemisia capillaris, Sonchus oleraceus and Taraxacum mongolicum, were analyzed and tested. The results showed that the water contents of the twelve wild vegetables were 73.94% - 92.06%, in which Phragmites australis had the highest water content, significantly higher than other wild vegetables. The ash contents were 0.67% - 5.75%, in which Sonchus oleraceus had the highest ash content, showing a significant difference compared to other wild vegetables. The VC contents were 49.70 - 382.70 mg/kg. Among them, Capsella bursa-pastoris, Zanthoxylum bungeanum leaves, Sonchus oleraceus and Carum carvi were comparable to green pepper (348.20 mg/kg) and cherry tomato (222.50 mg/kg) , which were high in VC content. The crude protein contents ranged from 0.91% to 5.81%, of which Toona sinesis was the highest with 5.81%. The crude fiber contents were 2.49% - 14.78%, among which the contents of Zanthoxylum bungeanum leaves, Carum carvi and Aralia chinensis buds were higher. Therefore, from the perspective of nutritional value, all twelve wild vegetables had value for further development and utilization. |
