| 为分析比较不同表型叶的木姜叶柯 Lithocarpus litseifolius 在不同月份二氢查耳酮类物质的含量
差异，研究通过高效液相色谱法对 7、8、9 和 10 月份采摘的大叶型、尖叶型和紫叶型木姜叶柯开展根皮
苷、三叶苷和根皮素含量比较分析。结果表明，不同表型叶的木姜叶柯干品中根皮素、根皮苷和三叶苷
含量存在显著性差异，其中大叶型木姜叶柯在 7 月份根皮素含量最高，同样在 7 月份采集的紫叶型木姜
叶柯三叶苷含量最高，达到 12.73%，尖叶型木姜叶柯中根皮苷含量整体高于大叶型和紫叶型；另外不同
采摘时间对 3 种有效成分含量亦有明显影响，在 7-10 月份的采收周期内，三种不同表型叶木姜叶柯中根
皮苷含量呈现升高趋势，而且大叶型略低于尖叶型和紫叶型；在 7 月份，大叶型、尖叶型和紫叶型木姜
叶柯中根皮素高于其它月份；就根皮素和三叶苷而言，不同样品在 8 和 9 月份采收时，其含量明显低于 7
月份和 10 月份样品中的含量。 |

| Abstract: |
| In order to analyze and compare the content differences of dihydrochalcone substances in
Lithocarpus litseifolius with different phenotypes leaves, high-performance liquid chromatography was used to
analyze the contents of phloridzin, trilobatin and phloretin from L. litseifolius of large-leaf, pointed-leaf and purple
leaves picked in July, August, September and October. The results showed that there were signi?cant differences
in the contents of phloretin, phlorizin and trilobatin in the different phenotypes leaves. Among them, the content of
phloretin in L. litseifolius with large-leaf type was the highest in July. Similarly, the trilobitin content in the purpleleaf
type samples collected in July was the highest, reaching 12.73%, and the phloridzin content in the pointedleaf
type samples was generally higher than that in the large-leaf type and purple-leaf type. In addition, different
picking times also had a signi?cant effect on the content of the three active ingredients. During the picking period
from July to October, the content of phloridzin in the three different phenotypes of L. litseifolius showed an
increasing trend, the contents of characteristic substances in the large-leaf samples slightly lower than pointed-leaftype and purple-leaf. The contents of phloretin in large-leaf, pointed-leaf and purple-leaf type samples obtained
from July were higher than those in other months. As far as phloretin and trilobatin were concerned, the contents
of different samples when picked in August and September were signi?cantly lower than those in the samples in
July and October. The results of this study have important reference values for clarifying the picking time of leaf
samples with different phenotypes and promoting the ef?cient use of resources. |
