从内蒙古和其它省区采集了37种荞麦,75%乙醇回流提取后用分光光度法测定总黄酮含量。结果表明,总黄酮含量(均值±2SD,单位:mg/kg)分别为,内蒙甜荞409.61±287.07(N=23),其中一个内蒙甜荞样品总黄酮含量(3553.42)极高未计入均值,其它省区甜荞503.51±411.29(N=7),差异不显著;实验室自去皮甜荞样品524.27±340.81(N=16),高于无皮甜荞样品(325.52±85.56,N=14),差异极显著(ρ=0.000);苦荞总黄酮含量(16177.23±1841.40,N=6)为甜荞(431.52±322.56,N=30)的37倍。测定结果为鲜有报道的内蒙古荞麦总黄酮含量提供了数据。
從內矇古和其它省區採集瞭37種蕎麥,75%乙醇迴流提取後用分光光度法測定總黃酮含量。結果錶明,總黃酮含量(均值±2SD,單位:mg/kg)分彆為,內矇甜蕎409.61±287.07(N=23),其中一箇內矇甜蕎樣品總黃酮含量(3553.42)極高未計入均值,其它省區甜蕎503.51±411.29(N=7),差異不顯著;實驗室自去皮甜蕎樣品524.27±340.81(N=16),高于無皮甜蕎樣品(325.52±85.56,N=14),差異極顯著(ρ=0.000);苦蕎總黃酮含量(16177.23±1841.40,N=6)為甜蕎(431.52±322.56,N=30)的37倍。測定結果為鮮有報道的內矇古蕎麥總黃酮含量提供瞭數據。

37 kindsof buckwheat samples from Inner Mongolia andother regions werecollected. Total flavonoids were extracted by 75% ethanol and determined by spectrophotometry. Results showed that total flavonoidscontent(mean±2SD,mg/kg)of Inner Mongoliacommon buckwheat was 409.61±287.07(N=23). Andcontentofother regionscommon buckwheat was 503.51±411.29(N=7). The difference was not significant. One sampleof Inner Mongoliacommon buckwheat,with high total flavonoidscontent(3 553.42),was not included in the average. Contentofcommon buckwheat samples which were peeled in laboratory was 524.27±340.81(N=16) and higher than hulless samples(325.52±85.56,N=14). The difference was significant(ρ=0.000). Tartary buckwheat (16 177.23±1 841.40,N=6) was 37 timesofcommon buckwheat(431.52±322.56,N=30) in total flavonoidscontent. The results provided data which were rarely reported for total flavonoidscontentof Inner Mongolia buckwheat.
