Abstract

Three new phenylpropanoid glycosides, phlinosides A, B and C were isolated from a methanolic extract of the aerial parts of Phlomis linearis. On the basis of chemical and spectral evidence their structures were determined as 3,4-dihydroxy-beta-phenylethoxy-O-beta-D-glucopyranosyl-(1----2)-a lpha-L- rhamnopyranosyl-(1----3)-4-O-caffeoyl-beta-D-glucopyranoside, 3,4 dihydroxy-beta-phenylethoxy-O-beta-D-xylopyranosyl-(1----2)-alpha- L- rhamnopyranosyl-(1----3)-4-O-caffeoyl-beta-D-glucopyranoside and 3,4-dihydroxy-beta-phenylethoxy-O-alpha-L-rhamnopyranosyl-(1----2) -alpha- L-rhamnopyranosyl-(1----3)-4-O-caffeoyl-beta-D-glucopyranoside, respectively.

摘要

从线叶糙苏地上部分的甲醇提取物中分离出三种新的苯丙素苷，即糙苏苷A、B和C。根据化学和光谱证据，确定它们的结构分别为3,4-二羟基-β-苯乙氧基-O-β-D-吡喃葡萄糖基-(1→2)-α-L-吡喃鼠李糖基-(1→3)-4-O-咖啡酰基-β-D-吡喃葡萄糖苷、3,4-二羟基-β-苯乙氧基-O-β-D-吡喃木糖基-(1→2)-α-L-吡喃鼠李糖基-(1→3)-4-O-咖啡酰基-β-D-吡喃葡萄糖苷和3,4-二羟基-β-苯乙氧基-O-α-L-吡喃鼠李糖基-(1→2)-α-L-吡喃鼠李糖基-(1→3)-4-O-咖啡酰基-β-D-吡喃葡萄糖苷。
