  摘要：

  从日本白头翁（Leucosceptrum japonicum (MIQ.) KITAMURA et MURATA）中分离出两种新的酰基糖苷，分别为白头翁苷A（IV）和白头翁苷B（V），同时还分离出了马尔丁苷（III）、阿克托苷（I）和阿克托苷异构体（II）。根据化学及光谱数据，IV和V的结构分别被确定为2-(3, 4-二羟基苯基乙基) 1-O-α-L-鼠李糖吡喃糖基-(1→3)-β-D-(4-O-咖啡酸)-葡萄糖吡喃糖苷和2-(3-羟基-4-甲氧基苯基乙基) 1-O-α-L-鼠李糖吡喃糖基-(1→3)-O-[β-D-阿糖苷[1→6]]-β-D-葡萄糖吡喃糖苷。

• Identification and occurrence of phenylethanoid and iridoid glycosides in six Polish broomrapes (Orobanche spp. and Phelipanche spp., Orobanchaceae)

  There are about 200 holoparasitic broomrapes (Orobanchaceae) known worldwide, however, only several species have been so far investigated phytochemically. Among Orobanche s.l. are both rare and endangered species, as well as onerous crop pests. This study aims to give a phytochemical description, both qualitative and quantitative, of six broomrape species (Orobanche and Phelipanche taxa) growing in Poland, including species that have not been tested in detail (O. caryophyllacea, O. linen, O. picridis, and P. arenaria). Sixteen metabolites, including 14 phenylethanoid glycosides (PhGs) and 2 iridoid glycosides (IrGs), were isolated and identified using NMR spectroscopy and hydrolysis, revealing the presence of two previously undescribed PhGs in P. ramosa, named ramoside A and 2'-acetylramoside A. In addition, in the example of O. caryophyllacea, we have reported as the first occurrence of IrGs in broomrapes. Concentrations of phenylethanoids, the main constituents of broomrapes, in the studied plant material (flowering shoots with haustoria) were determined using the UHPLC-PDA method. It was found that P. ramosa has been the richest source of PhGs. In addition, the differences between broomrapes have been visualized using principal component and cluster analysis. The results of the antiradical DPPH test of 13 PhGs confirmed previous findings on the relation of the antioxidant potential with the structure of phenolic moieties - phenolic acid and phenylethanoid unit.

  The present invention provides a composition comprising an effective amount of benfotiamine and an effective amount of pyridoxamine in a suitable vehicle for topical application. The present compositions are useful in improving the appearance of aged skin characterized by wrinkles, loss of elasticity, and hyperpigmentation caused by chronoaging and/or photoaging of skin, by inhibiting particularly skin damage resulting from reactive carbonyl species (RCS), glycation of skin proteins, formation of advanced glycation endproducts (AGEs) and formation of advanced lipoxidation endproducts (ALEs).
