The main nutrient content and mineral element content in fresh bamboo shoots of Pleioblastus amarus(Keng)Keng f.,P.juxianensis T.H.Wen et al.and P.maculatus(McClure) C.D.Chu et C.S.Chao were determined.The results show that the water content in fresh bamboo shoots of P.amarus,P.juxianensis and P.maculatus is 91.32%,90.87% and 91.69%,respectively,and the difference is not significant.And crude fiber content is 13.9,18.8 and 19.3 g·kg-1,crude fat content is 8.90,7.20 and 6.60 g·kg-1,ash content is 10.90,4.10 and 7.60 g·kg-1,VC content is 0.133,0.154 and 0.087 g·kg-1,crude protein content is 21.2,19.5 and 14.0 g·kg-1,reducing sugar content is 0.80,1.20 and 2.20 g·kg-1,respectively,and the significant difference exists among the three species.K content in fresh bamboo shoots of the three species is the highest(1 152.8-1 628.1 μg·g-1),and Ca and Mg contents are 63-86 μg·g-1.Zn content in that of P.amarus,P.juxianensis and P.maculatus is 22.4,21.9 and 20.3 μg·g-1,respectively,and the difference is not obvious.Otherwise,there is 16.2 μg·g-1 Fe and 0.30 μg·g-1 Cr in fresh bamboo shoots of P.amarus,but Fe and Cr can not be detected in that of P.juxianensis and P.maculatus.
The main nutrient content and mineral element content in fresh bamboo shoots of Pleioblastus amarus （Keng） Keng f., P. juxianensis T. H. Wen et al. and P. maculatus （McClure） C. D. Chu et C. S. Chao were determined. The results show that the water content in fresh bamboo shoots of P. amarus, P. juxianensis and P. maculatus is 91.32%, 90.87% and 91.69%, respectively, and the difference is not significant. And crude fiber content is 13.9, 18.8 and 19.3 g · kg-1, crude fat content is 8.90, 7.20 and 6.60 g · kg^-1, ash content is 10.90, 4.10 and 7.60 g · kg^-1, Vc content is 0. 133, 0. 154 and 0. 087 g · kg^-1 , crude protein content is 21.2, 19.5 and 14.0 g · kg^-1 , reducing sugar content is 0. 80, 1.20 and 2.20 g · kg^ -1, respectively, and the significant difference exists among the three species. K content in fresh bamboo shoots of the three species is the highest （ 1 152.8 - 1 628.1 μg · g^-1 ）, and Ca and Mg contents are 63-86μg·g^-1 Zn content in that of P. amarus, P. juxianensisandP, maculatusis 22.4, 21.9and20.3 μg · g^-1 , respectively, and the difference is not obvious. Otherwise, there is 16.2 μg · g^-1 Fe and 0. 30 μg · g^-1 Cr in fresh bamboo shoots of P. amarus, but Fe and Cr can not be detected in that of P. juxianensis and P. maulatus.
