摘    要:野生党参是甘肃子午岭地区的一种重要的植物资源。为评估甘肃子午岭地区野生党参的营养价值,以甘肃渭南地区的栽培党参为对照,对二者根中总黄酮、可溶性糖和可溶性蛋白含量进行对比分析。结果表明,甘肃子午岭野生党参根中总黄酮含量和可溶性蛋白含量分别为0.040,0.204 mg·g-1,较甘肃渭南栽培党参分别显著提高了11.11%,7.93%,但可溶性糖含量(0.213 μg·g-1)显著降低了78.40%。综合说明,甘肃子午岭野生党参在总黄酮物质和可溶性蛋白方面具有较高的利用价值。

Abstract: The wild Codonopsis pilosula is one of the most important resourcesin Ziwuling area of Gansu Province. To evaluate the nutritive value of wild C. pilosula in Ziwuling area of Gansu Province, cultivated C. pilosula in Weinan area of Gansu Province was taken as the control, the content of total flavonoid, soluble sugar, and soluble protein inthe roots of wild C. pilosula were analyzed.The results showed that compared with cultivated C. pilosula in Weinan of Gansu, the contents of total flavonoid and soluble protein in the roots of wild C. pilosula were 0.040,0.204 mg·g-1, respectively, which were significantly increased by 11.11%, 7.93%, respectively, but the soluble sugar content in roots of wild C. pilosula(0.213 μg·g-1)was significantly reduced by 78.40%. The results suggested that wild C. pilosula of Ziwuling area has a high utilization value in terms of total flavonoid and soluble protein.

黨参(Codonopsis pilosula (Franch.) Nannf.)为桔梗科党参属多年生草本植物,是我国著名的药食同源植物,含有多种药用成分,如生物碱类、炔类、萜类、黄酮类、木质素类、甾体类、糖类等成分,其中生物碱类、聚炔类、木脂素类、黄酮类化合物和多糖被认为是主要的活性成分[1-2],对脾肺虚弱、气虚、气短、少食多便、咳嗽、内热、口渴等症有治疗作用[3]。党参在我国应用历史悠久、运用范围广泛,是滋补的良品。

党参常野生于山地和灌木林中,海拔大致为1 500~3 000 m,甘肃是其主要产区[4]。甘肃子午岭地区属于东亚季风气候区,年均温7.14~8.15 ℃,年均降水量为500~620 mm,年平均相对湿度为63 %~68 %,乔木、灌木种类丰富,树冠的郁闭程度为70%~90%,由于林区季风气候和大陆性特征共存,水资源丰富,气候温暖潮湿,是野生动植物依赖的栖息地[5],野生党参即是一种重要的可被当地百姓常用的药食同源植物资源。……
