摘要 [目的] 对哈尔滨市主栽花楸果实主成分进行测定分析。[方法]以哈尔滨市主栽的5个花楸种源的花楸果实作为研究材料,对它们进行了可溶性糖、总黄酮、芦丁等次生代谢产物含量的测定。[结果]5个花楸种源中的欧洲花楸US05果实中可溶性总糖、总黄酮和芦丁含量均显著高于其他种源,分别达到6.389%、1.564 1%和6.986 744 μg/ml。[结论]筛选出欧洲花楸US05为适于哈尔滨地区栽培的药用花楸种源。

Abstract [Objective] The composition of the main planting Sorbus pohuashanesis fruit in Harbin was determined and analyzed. [Method] Choosing five provenances of Sorbus pohuashanesis fruit which main cultivated in Harbin as material,their secondary metabolites such as soluble sugar, total flavonoids, rutin were determined .[Result]The results showed that content of secondary metabolites such as soluble sugar, total flavonoids of Sorbus aucuparia L. US05 fruit have reached a significant level between these provenances, respectively reached 6.389%, 1.564 1%, 6.986 744 μg/ml. [Conclusion]Sorbus aucuparia L. US05 could thus be screened filter out the provenance of medicinal plant which was suitable for cultivation in Harbin.

花楸(Sorbus spp.)为蔷薇科花楸属落叶小乔木,该树种春季观叶、夏季观花、秋冬观果,是城市园林绿化的优良树种;同时该树种具有结果早、产量高、适应性强,且富含黄酮类等化合物的特点,是一个集园林绿化、食用、药用等价值于一身的珍贵灌木浆果树种[1-2]。黄酮类化合物对人类健康有重要作用,其对体内自由基有明顯的清除作用,并可抑制细胞的调亡,是治疗心血管疾病药物的主要成分,由于黄酮类化合物具有广谱的药理活性和较低毒性,是目前人们比较关注的一类化合物,已成为国内外天然药物开发利用研究的热点[3]。该研究通过对哈尔滨市主要栽植的5个花楸种源的花楸果实进行主要成分分析,定向筛选适于哈尔滨地区栽培的药用花楸种源。
