Acylated kaempferol glycosides from the flowers of delphinium formosum

Abstract One new flavonol glycoside, kaempferol 3-(4″,6″-diacetylglucoside)-7-rhamnoside and three other known kaempferol glycosides: kaempferol 3-glucoside-7-rhamnoside, kaempferol 3-(6″-acetylglucoside)-7-rhamnoside, and kaempferol 7-rhamnoside, were isolated and characterised from flowers of Delphinium formosum. The structures were elucidated by spectral and chemical methods.

Norditerpenoid alkaloids from Delphinium formosum

Abstract From the aerial parts of Delphinium formosum , a new norditerpenoid alkaloid, N -acetyldelectine (14-demethylajacine), was isolated, in addition to six known compounds, lycoctonine, delsemine A, delsemine B, delectine, delcosine and anthranoyllycoctonine. The structures of the compounds were determined by spectroscopic methods.

The Quantitative Determination of some Phenolic Acids In Delphinium Formosum by HPLC

ABSTRACT Some phenolic acids from the flowers of Delphinium formosum have been determined quantitatively by reversed-phase high-performance liquid chromatography with diode-array detection. A comparative study was performed by extracting the following phenolic acids: p-hydroxy benzoic, p-coumaric, caffeic, protocatechuic and vanillic acids with four different methods. The results were supported with recovery studies.
