METHODS AND RESULTS:
A new method for analyzing the ingredients of evodiamine(EV), rutaecarpine(RU), Hydroxyevodiamine(HYD), evodiamide(ED), dihydrorutaecarpine(DRU) and 14-formyldihydrorutaecarpine(FDRU)in evodia rutaecarpa using high performance thin layer chromatography (TLC) and surface enhanced Raman spectroscopy (SERS) technique is reported. The character of this method is that standard samples are not needed . The results show that the characteristic spectral bands of EV, RU, Hydroxyevodiamine, and ED can be obtained from the TLC spot with microgramme of sample. The spectral band at 1 562 cm-1 was obtained with great enhancement. Molecule absorbed in surface silver sol by π electrons in ring.
CONCLUSIONS:
The spectral bands of EV, RU, Hydroxyevodiamine and ED are obviously different due to their differences in structure. | | 《Natural Product Research and Development》 2004-01 | | STUDIES ON THE CHEMICAL CONSTITUENTS OF EVODIA RUTAECARPA VAR. OFFICINALIS[Reference: WebLink] |
METHODS AND RESULTS:
From the fruits of Evodia rutaecarpa var. officinalis,15 compounds were isolated,and their structures were determined on the spectral evidences as evodiamine(1),rutaecarpine(2),Hydroxyevodiamine(3),14-formyldihydro-rutaecarpine(4),evodiamide(5),goshuyuamide-I(6),dihydroevocarpine(7),skimmianine(8),quercetin-3-O-β-D-galactoside (9),isorhamnetin-3-O-β-D-galactoside(10),rutaevine(11),β-sitosterol(12),daucosterol(13),palmatic acid(14),stearic acid(15),respectively.
CONCLUSIONS:
Among them,compound 4～6,8～10 and 12～15 were obtained from this plant for the first time. |
