Sparins A–C (1–3, resp.), three new flavonoids, were isolated from the CHCl3 subfraction of the EtOH extract of the whole plant of Spiraea brahuica, along with 3′,7‐di‐O‐methylquercetin (4) and luteolin 7‐β‐D‐glucopyranoside (5), reported for the first time from this species. The structures of the new compounds were elucidated by spectroscopic techniques including MS and 2D‐NMR spectroscopy.
Sparins A-C(1 - 3。,RESP),三个新的黄酮类化合物,是从三氯甲烷分离3的整个植物的乙醇提取物的亚级分绣线brahuica,连同3',7-二Ö -methylquercetin(4)和木犀草素7- β - D-吡喃葡萄糖苷(5),这是该物种的首次报道。通过包括MS和2D-NMR光谱在内的光谱技术阐明了新化合物的结构。
