测定了三种形态型莎草块茎和块茎油的块茎特征和营养成分。块茎长度和宽度的平均值以及1000个干燥块茎的重量分别为0.98至1.31厘米、0.90至1.19厘米和598至1044克。块茎显示出高水平的淀粉（30.54–33.21 g 100 g−1）、脂质（24.91–28.94 g 100 g−1）和蔗糖（17.98–20.39 g 100 g−1）。与黑色块茎相比，黄色块茎的脂质含量明显更高。三种形态类型的抗坏血酸、生育酚和β-胡萝卜素水平存在显着差异。黄色（形态类型 1 和 2）的生育酚含量最丰富，而 β-胡萝卜素含量最差。形态类型2的饱和脂肪酸含量显着低于形态类型1和3。与形态类型1和2相比，形态类型3的PUFA含量显着最低。发现形态类型1的Ca、Cu和Mn含量更丰富。形态 2 中 Al、Mg、P、S 和 Si 含量最高。形态 3 中 Cl、K 和 Zn 含量最高。
Tuber characteristics and nutrient composition of three morphotypes of Cyperus esculentus tubers and tuber oils were determined. The mean value for length and width of the tuber and one thousand dried tuber weights ranged from 0.98 to 1.31 cm, 0.90 to 1.19 cm, and 598 to 1044 g, respectively. Tubers displayed high level of starch (30.54–33.21 g 100 g−1), lipid (24.91–28.94 g 100 g−1), and sucrose (17.98–20.39 g 100 g−1). The yellow tubers had significantly higher content in lipid compared to black ones. Levels of ascorbic acid, tocopherol, and β-carotene of the three morphotypes differed significantly. Yellow ones (morphotypes 1 and 2) were the richest in tocopherol and the poorest in β-carotene. Saturated fatty acid content of morphotype 2 was significantly lower than that of morphotypes 1 and 3. Morphotype 3 had the significantly lowest PUFA content compared to morphotypes 1 and 2. Morphotype 1 was found to be richer in Ca, Cu, and Mn contents. Al, Mg, P, S, and Si were most abundant in morphotype 2. Morphotype 3 had the highest content of Cl, K, and Zn.
