Bergapten angelica

Angelica amurensis Schischk. A. anomala Lallem. A. dahurica (Fisch.) Benth. et Hook. Byak-angelicin, byak-angelicol, oxypeucedanine, imperatorin, phellopterin, xanthotoxine, marmesin, scopoletin, marmesin, scopoletin, anomalin, angenomalin, bergapten.33 Antipyretic, treat toothache, headache. Externally for mastitis and wound infection. 

Coumarins bergapten, umbelliferone generally lower coumarin content than Angelicae and Imperatoriae radix Phtalide 3-butylidenephtalide (ligusticum-lacton)... 

In the Rf range 0,55-0.65, the main blue fluorescent ostruthin and the brown imperatorin zone dominate the TLC picture of Imperatoriae radix (1), while in Angelicae radix 2 two prominent bright fluorescent zones of that R, range contain angelidn, imperatorin, xanthotoxin, bergapten and osthenol. 

Certain coumarins (e.g., bergapten and xanthotoxin) are phototoxic (see angelica and bergamot oil). 

A sensitive, specific, and rapid LC-MS method has been developed and validated for the simultaneous determination of xanthotoxin, psoralen, isoim-pinellin, and bergapten [80]. A paper by Zheng et al. [81] reported the quantitation of eleven coumarins including furocoumarins in Angelica dahurica, using HPLC-ESl-MS/MS. Yang et al. [82] developed a method for the characterization of linear furanocoumarins in Radix glehniae by LC-MS by the...
