目的：对云南省西南部地区产四方蒿花序化学成分进行研究。方法：用化学法及光谱分析法分离和鉴定其化学成分。结果：从云南省西南部地区产四方蒿花序水提取物中分得４个黄酮甙，结构分别确定为异紫云英甙，木犀草素７葡萄糖甙，木犀草素３′葡萄糖甙，木犀草素７半乳糖甙。结论：４个黄酮甙均为首次从该植物中分得 Objective: To study the chemical composition of Artemisia sacchariflora in the southwest of Yunnan Province. Methods: The chemical components were separated and identified by chemical and spectral analysis. RESULTS: Four flavonoids were obtained from the water extract of Artemisia halodendron in the southwest of Yunnan Province. The structures were identified as isovunoxime, luteolin-7glucoside, and luteolin-3′glucose.甙, luteolin  7 galactose oxime. Conclusion: All four flavonoids were obtained from this plant for the first time
