The study investigated, for the first time, proximate nutritional composition and antioxidant activity of gonads from the sea urchin, Stomopneustes variolaris, inhabiting the coastal area of Visakhapatnam (India). Moisture, ash, proteins, lipids and carbohydrate content were 77.53%±0.80, 3.76%±0.25, 12.10%±0.41, 4.98%±0.36 and 1.63%±0.18, respectively, based on dry weight. The gonads were rich in essential amino acids (ca. 32.1% of total amino acids) with the most predominant being phenylalanine, lysine and valine. The essential to non-essential amino acid ratio was 0.5. Polyunsaturated fatty acids (PUFA) constituted 22.01%±2.2 of total fatty acids. The ω6:ω3 ratio was 0.94. Total phenol content of the gonad was 9.90±0.01 mg GAE/g and the IC50 of the extract, using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay, was 57.81 μg/ml.
该研究首次调查了栖息在印度维沙卡帕特南沿海地区的多变刺冠海胆性腺的近似营养成分和抗氧化活性。基于干重，水分、灰分、蛋白质、脂质和碳水化合物含量分别为77.53%±0.80、3.76%±0.25、12.10%±0.41、4.98%±0.36和1.63%±0.18。性腺富含必需氨基酸（约占总氨基酸的32.1%），其中最主要的是苯丙氨酸、赖氨酸和缬氨酸。必需氨基酸与非必需氨基酸的比例为0.5。多不饱和脂肪酸（PUFA）占总脂肪酸的22.01%±2.2。ω6:ω3比例为0.94。性腺的总酚含量为9.90±0.01毫克没食子酸当量/克，使用1,1-二苯基-2-苦基肼（DPPH）法测定提取物的IC50为57.81微克/毫升。
