从红木荷（Ｓｃｈｉｍａｗａｌｉｃｈｉ（ＤＣ）Ｋｏｒｔｈａｌｓ）树皮中分离出４个化学成分，经光谱解析和化学降解，分别被鉴定为α－菠甾醇（Ａ），α－菠甾醇葡萄糖甙，表儿茶素和一新的三萜皂甙２２－Ｏ－当归酰酯Ａ１－ｂａｒｒｉｇｅｎｏｌ－３－Ｏ－［α－Ｌ－鼠李吡喃糖基（１→２）］－［β－Ｄ－葡萄吡喃糖基（１→２）－β－Ｄ－半乳吡喃糖基（１→４）］－β－Ｄ－葡萄糖醛酸甙。
Four chemical constituents were isolated from the barks of Schimawalichi (DC) Korthals and were identified as α-spinositols (A), α-stilbene glucoside, epicatechin And a new triterpene saponin 22-O- angeloyl ester A1-barrigenol-3-O- [α-L-rhamnopyranosyl (1 → 2)] - [β-D-glucopyranosyl (1 → 2) -β-D-galactopyranosyl (1 → 4)] - β-D-glucuronide.
