In the current phytochemical research on ginseng, the differentiation and structural identification of ginsenosides isomers remain challenging. In this paper, a two-dimensional mass spectrometry (2D-MS) method was developed and combined with statistical analysis for the direct differentiation, identification and relative quantification of protopanaxadiol (PPD)-type ginsenoside isomers.

The synergistic effect of maclurin on CK-induced inhibition of the transcriptional expression of MMP-1 was investigated in HaCaT human keratinocyte cells. Maclurin suppresses transcriptional expression of MMP-1 via inhibition of ERK/Ets-1 signaling. The combination of CK and maclurin may be promising way to be used as an anti-skin aging agent.
