Embodiment 1
[0039] The manufacture method of oxojiangyao hydroxyalkenic acid
[0040]Cut the whole grass of fresh Hemerocallis finely, use methanol as solvent, and extract at room temperature for 1 week. Then, it was filtered and the filtrate was concentrated, combined ion exchange resin (Diaion HP-20), cis-phase silica gel, gel filtration (Sephadex, GS) in open column chromatography, combined gel filtration in split-recycle HPLC (Sephadex, GS), and the obtained solid (hereinafter referred to as "methanol extract") was separated to obtain oxojiangyao hydroxyalkenine.
[0041] The results obtained for the data obtained with respect to oxo-hydroxyalkenine are as follows.
