摘    要:本文研究了刺五加(Acanthopanax senticosus)丁香苷和总黄酮含量的季节变化。结果表明, 丁香苷主要存在于茎干系统, 其中在枝中的含量最高, 平均含量可达2.94%。从季节动态来看, 刺五加地上部分枝和茎中丁香苷的含量呈明显的季节变化, 即春秋季含量较高, 夏季含量较低; 地下部分根和根茎中丁香苷含量的季节变化不明显。刺五加全株均含有总黄酮, 刺五加地上部分总黄酮的含量呈明显的季节变化, 其叶片总黄酮在5月中下旬林分郁闭之前含量最高, 平均含量可达3.8%; 茎干中总黄酮春季较高, 夏季降低, 而到晚秋时含量最高, 其中枝中总黄酮平均含量可达3.75%。地下部分总黄酮含量的季节变化不十分明显。本文对丁香苷和总黄酮季节变化的原因进行了分析。

关 键 词:刺五加  丁香苷  总黄酮  季节动态

Abstract:In this paper, the contents of syringin and total flavonoid in different parts of Acanthopanax senticosus according to seasonal dynamics were determined. Syringin mainly exists in branches, stems, rhizomes and roots, but in branches, the average content is 2.94%, which is the highest in all parts of A. secticosus. The syringin content of the aboveground parts shows a distinct seasonal dynamics. It is higher in the spring and autumn but lower in the growth season (summer). However, the syringin content of underground parts does not show a distinct seasonal dynamics. All parts of A. senticosus contain flavonoid. The content of total flavonoid in the leaves shows a distinct dynamics. The highest content, about 3.8%, occurs in the middle of May before the forest canopy closure. The content of total flavonoid in branches and stems also shows a distinct seasonal dynamics: higher in the spring and autumn, but lower in summer. In the branches, the average content of total flavonoid reaches 3.75% in autumn. But the total flavonoid content of the underground parts does not show a distinct seasonal dynamic. The reasons for the seasonal dynamics of the syringin and total flavonoid of A. senticosus are discussed.
