摘要: 以桉树(Eucalyptus spp.)林套种的草豆蔻(Alpinia katsumadae Hayata)和自然生长的草豆蔻为研究对象,测定草豆蔻营养器官(根、茎、叶)中总黄酮、多糖、总酚、总皂苷含量和折干率。结果表明,自然生长的草豆蔻整株折干率是桉树林套种的1.11倍;草豆蔻的总黄酮含量为10.27~32.13 mg/g,其中桉树林套种的草豆蔻叶总黄酮含量最高,达32.13 mg/g;草豆蔻多糖含量为21.50~37.28 mg/g,自然生长条件下草豆蔻整株多糖含量是桉树林套种的1.15倍;桉树林套种条件下草豆蔻整株总酚含量是自然生长条件下草豆蔻总酚含量的2.10倍;桉树林套种条件下草豆蔻整株总皂苷含量是自然生长条件下草豆蔻整株总皂苷含量的1.25倍;由主成分分析可知,桉树林套种条件下草豆蔻的营养器官综合得分和排名均高于自然生长。综上,2种种植模式下草豆蔻营养器官的药用成分含量均处于较高水平,且桉树林套种条件下草豆蔻更有利于有效成分的累积。

Abstract: Using Alpinia katsumadae Hayata from Eucalyptus forest intercropping and Alpinia katsumadae Hayata from natural growth as research objects, the total flavonoid, polysaccharide, total phenolic, total saponin content and drying rate of Alpinia katsumadae Hayata nutritional organs (roots, stems, leaves) were determined. The results showed that the whole plant drying rate of Alpinia katsumadae Hayata with natural growth was 1.11 times that of Eucalyptus forest intercropping;the total flavonoid content of Alpinia katsumadae Hayata was 10.27~32.13 mg/g, among which Eucalyptus forest intercropping had the highest total flavonoid content in the leaves of Alpinia katsumadae Hayata, reaching 32.13 mg/g;the polysaccharide content of Alpinia katsumadae Hayata was 21.50~37.28 mg/g. Under natural growth conditions, the total polysaccharide content of Alpinia katsumadae Hayata was 1.15 times that of Eucalyptus forest intercropping;the total phenolic content of Alpinia katsumadae Hayata under the condition of Eucalyptus forest intercropping was 2.10 times that of Alpinia katsumadae Hayata under the condition of natural growth;the total saponin content of Alpinia katsumadae Hayata under the condition of Eucalyptus forest intercropping was 1.25 times that of Alpinia katsumadae Hayata under the condition of natural growth;according to principal component analysis, under the condition of Eucalyptus forest intercropping, the comprehensive score and ranking of the nutritional organs of Alpinia Katsumadae Hayata were higher than those of natural growth. In summary, the medicinal component content of the nutritional organs of Alpinia katsumadae Hayata was at a high level under both planting modes, and the Eucalyptus forest intercropping condition was more conducive to the accumulation of effective ingredients of Alpinia katsumadae Hayata.

Key words: Alpinia katsumadae Hayata, Eucalyptus spp. forest, medicinal components, nutritional organs
