The concentrations of isoflavones and anthocyanins in five soybean seed cultivars of three different planting dates were determined in this study. Among the seeds of three different planting dates, the highest concentration of average total isoflavones (4098 μg g(-1)) was measured in those from early July, whereas the lowest concentration of average total isoflavones (3238 μg g(-1)) was measured in those from late May. Anthocyanin compounds were detected only in the Cheongjakong 3 cultivar. Among the three different planting dates, late-planted Cheongjakong 3 accumulated the highest concentration of total anthocyanins (10103 μg g(-1)), whereas the variety at an earlier planting date exhibited the lowest concentration of average total anthocyanins (7115 μg g(-1)). On the basis of these results, it was concluded that environmental factors such as temperature and precipitation may change the isoflavone and anthocyanin contents of soybean, altering the nutritional values of soy products.
本研究测定了三个不同种植日期的五个大豆品种种子中异黄酮和花青素的浓度。在三个不同种植日期的种子中，7 月初收获的大豆中总异黄酮（4098μg g(-1)）的平均浓度最高，而 5 月底收获的大豆中总异黄酮（3238μg g(-1)）的平均浓度最低。花青素化合物仅在昌佳空 3 号品种中检测到。在三个不同的种植日期中，种植时间较晚的昌佳空 3 号积累了最高浓度的总花青素（10103μg g(-1)），而较早种植的品种总花青素的平均浓度最低（7115μg g(-1)）。基于这些结果，可以得出结论，温度和降水等环境因素可能会改变大豆中的异黄酮和花青素含量，从而改变豆制品的营养价值。
