From the aerial parts of Solenostemma argel, four new acylated phenolic glycosides sinapyl alcohol 9-O-feruloyl-4-O-alpha-rhamnopyranosyl-(1-->2)-beta-glucopyranoside, solargin I (1), sinapyl alcohol 9-O-caffeoyl-4-O-alpha-rhamnopyranosyl-(1-->2)-beta-glucopyranoside, solargin II (2), sinapyl alcohol 9-O-feruloyl-4-O-alpha-rhamnopyranosyl-(1-->2)-alpha-rhamnopyranosyl-(1-->2)-beta-glucopyranoside, solargin III (3) and sinapyl alcohol 9-O-caffeoyl-4-O-alpha-rhamnopyranosyl-(1-->2)-alpha-rhamnopyranosyl-(1-->2)-beta-glucopyranoside, solargin IV (4) have been isolated. The structures of the isolated compounds were verified by means of MS and NMR spectral analyses.
从阿尔及利亚牛心朴子的地上部分，分离得到了四种新的酰化酚苷，即芥子醇9 - O - 阿魏酰基 - 4 - O - α - 鼠李糖基 - (1→2) - β - 葡萄糖苷、索拉金I（1）、芥子醇9 - O - 咖啡酰基 - 4 - O - α - 鼠李糖基 - (1→2) - β - 葡萄糖苷、索拉金II（2）、芥子醇9 - O - 阿魏酰基 - 4 - O - α - 鼠李糖基 - (1→2) - α - 鼠李糖基 - (1→2) - β - 葡萄糖苷、索拉金III（3）以及芥子醇9 - O - 咖啡酰基 - 4 - O - α - 鼠李糖基 - (1→2) - α - 鼠李糖基 - (1→2) - β - 葡萄糖苷、索拉金IV（4）。通过质谱和核磁共振光谱分析对分离得到的化合物结构进行了确证。
