[A new alkaloid from the husk of Xanthoceras sorbifolia].
OBJECTIVE
To study the chemical constituents from the husk of Xanthoceras sorbifolia Bunge. Repeated column chromatography on silica gel and preparative TLC were used to isolate the compounds whose structures were elucidated based on spectroscopic data (ESIMS, EIMS, 1D and 2D NMR).


RESULTS
A new alkaloid was isolated and identified as: 2-methyl-6-(2', 3', 4'-trihydroxybutyl)-pyrazine (I), along with nine known compounds: cleomiscosin D (II), naringenin (III), eriodictyol (IV), kaempferol (V), quercetin (VI), rutin (VII), 5,7-dihydroxychromone (VIII), tyrosol (IX), 1-O-methyl-myo-inositol (X).


CONCLUSIONS
Compound I is a new alkaloid, compounds II, IV, V, VII - X were isolated from this genus for the first time.
