Two new bisabolane sesquiterpenoids, 1 and 2, along with five known ones, 13‐hydroxyxanthorrhizol (3), 12,13‐epoxyxanthorrhizol (4), xanthorrhizol (5), β‐curcumene (6), and β‐bisabolol (7), were isolated from the rhizomes of Curcuma xanthorrhiza Roxb. The chemical structures of the new compounds were determined to be (7R,10R)‐10,11‐dihydro‐10,11‐dihydroxyxanthorrhizol 3‐O‐β‐D‐glucopyranoside (1) and
两种新的双倍半萜类倍半萜化合物1和2,以及五个已知的倍半萜类倍半萜类化合物,分别为13-羟基黄苯二酚(3),12,13-环氧黄苯二酚(4),黄嘌呤唑(5),β-姜黄素(6)和β-双萘酚(7)中,从根茎分离莪黄根 的罗。新化合物的化学结构确定为(7 R,10 R)‐10,11‐二氢‐10,11‐二羟基黄药酚3‐ O ‐ β ‐ D‐吡喃吡喃糖苷(1)和(-)-氢氢醌2,5-二-O - β - D-吡喃葡萄糖苷(2)基于1D-和2D-NMR光谱分析和旋光特性。化合物2和3降低了经UVB处理的人角质形成细胞中MMP-1的表达。在mRNA水平上分别是8.9倍和7.6倍。在蛋白质水平上分别是9.2倍和6.6倍。结果表明,分离出的化合物可能通过抑制皮肤细胞中MMP-1的表达而具有抗衰老作用。
