Norditerpenoid alkaloids from Delphinium species

Five New C19‐Diterpenoid Alkaloids from Delphinium tianshanicum W.T.Wang

“…The absence of correlation between H–C(13) and H–C(16), as shown by COSY ( Fig. ), indicated that D ‐ring adopt boat conformation and the 16‐MeO was installed in β ‐confirguration . In the NOESY spectrum, the cross‐peak between 16‐MeO and H–C(13) further confirmed the configuration of 16‐MeO.…”

“…Ten known compounds, methyllycaconitine ( 6 ), shawurensine ( 7 ), delavaine A ( 8 ), delavaine B ( 9 ), delsemine A ( 10 ), delsemine B ( 11 ), tianshanisine ( 12 ), delcorine ( 13 ), 6‐deoxydelpheline ( 14 ) and blacknidine ( 15 ), were identified by comparison of their spectroscopic data with the literature data.…”

An overview of the chemical constituents from the genus Delphinium reported in the last four decades

“…[33][34][35][36][37] Budelphine (36) from D. buschianum possesses a rare 1,2-epoxy group. 36 There are 12 alkaloids (39)(40)(41)(42)(43)(44)(45)(46)(47)(48)(49)(50) with an N-CHO formamide group formed from a C-21 aldehyde. 4,[38][39][40][41][42][43][44][45] Among these compounds, alkaloids 41-45 are DAs that have no oxygen-containing group at C-16.…”

Chromone and flavonol glycosides from Delphinium hybridum cv. “Belladonna Casablanca”

“…As regards its constituents, a number of alkaloids have been isolated from the roots and the aerial parts [2]. Moreover, acylated kaempferol glycosides in the flowers of D. formosum are reported [3].…”

“…As part of our continuing investigation on the chemical constituents in the Ranunculaceous plants [4][5][6], we report one new chromone glycoside (1) isolated from D. hybridum cv. ''Belladonna Casablanca,'' together with six known flavonol glycosides (2)(3)(4)(5)(6)(7).…”
