【摘要】：目的評估堇葉碎米薺食用和藥用價值。方法分別采用酸水解氨基酸自動分析法、原子熒光光度法、紫外分光光度法和苯酚-硫酸法,分析不同生境條件下,堇葉碎米薺氨基酸、硒、總黃酮和粗多糖含量。結(jié)果堇葉碎米薺作為一種新食品原料,其抽苔期栽培植株和野生植株全氨基酸含量分別為18.55g/100g和20.53g/100g,而在期栽培植株中含量較低(8.44g/100g);除脯氨酸外,抽苔期的栽培與野生植株樣品中其它16種氨基酸含量基本相同,但前者必需氨基酸所占比例(43.29%)高于后者(38.48%)。值得注意的是野生植株樣品中含有豐富的脯氨酸,其含量高達(dá)2.88%,是大棚栽培樣品的3~5倍。大棚補(bǔ)硒栽培的2個樣品硒含量分別為199μg/100g和194μg/100g,而生長于高硒地帶上的野生植株樣品(ES-wild)硒含量為177μg/100g。結(jié)莢期栽培植株的總黃酮含量(529mg/100g)高于野生植株(478mg/100g))和抽苔期栽培植株(474mg/100g),其粗多糖含量(1.05g/100g)也略高于野生植株(0.97g/100g)和抽苔期栽培植株(0.87g/100g)。結(jié)論堇葉碎米薺作為功能性食品原料開發(fā)利用,需考慮不同生境條件對其化學(xué)成分的影響。
[Abstract]:Objective to evaluate the edible and medicinal value of Cardamine pansy. Methods Acid-hydrolyzed amino acid automatic analysis, atomic fluorescence spectrophotometry, ultraviolet spectrophotometry and phenol-sulfuric acid method were used to analyze the amino acids of Cardamine pansy under different habitats. Results as a new food material, the total amino acid contents of cultivated plants and wild plants were 18.55g/100g and 20.53g / 100g, respectively, but the contents of total amino acids in cultivated plants were lower than 8.44g / 100g / 100g, except for proline. The content of other 16 amino acids in the wild plant samples was almost the same, but the proportion of essential amino acids in the former was 43.29), which was higher than that in the latter one (38.48). It is worth noting that the wild plant samples contain abundant proline. The selenium content of the two samples was 199 渭 g / 100 g and 194 渭 g / 100 g, respectively, while that of wild plants growing on the high selenium belt was 177 渭 g / 100 g. The total flavonoids of the plants cultivated in pod stage were 177 渭 g / 100 g. 529mg / 100g) was higher than wild plant 478mg / 100g) and cultivated plant at sprouting stage 474mg / 100g. Its crude polysaccharide content was also slightly higher than that of wild plant 0.97g / 100g) and sprouts 0.87g / 100g.Conclusion Cardamine pansa is used as a functional food raw material. The effects of different habitat conditions on their chemical composition should be considered.
