A New Alkaloid from Delphinium leptocarpum

A systematic review on the chemical constituents of the genus Consolida (Ranunculaceae) and their biological activities

“…The indolinopyrrole fragment is bound to the hetisine-type C 20 -DA part through an a-directed (relative to the indoline core) C-17-C-3 bond according to an Xray crystal structure analysis. 19 In addition, several of the new alkaloids possess at least one uncommon substituent. For example, new C 18 -DAs 1 and 2 possess an uncommon 3,4epoxide unit, 20,21 and new alkaloids 35 and 71 have an N-C (19) ] O lactam group.…”

Chemistry, biological activities and toxic effects of alkaloidal constituents of genus Delphinium - A mini review

“…Their data demonstrated the presence of 10 diterpenoid alkaloids in the extracts of the plant, including lycoctonine, caerudelphinine A, talitine A-C, tatsienine-V, d-magnoflorine, vakhmatine, delatisine, and a propionate derivative (28). Kurbanov et al revealed that the aerial parts of D. leptocarpum during flowering season possessed a new alkaloid compound with a formula of C 34 H 43 N 3 O 3 that was called leptanine (53). The genus D. delavayi Franch has been described to contain several diterpenoid alkaloid compounds; however, deltaline with formula C 27 H 41 NO 8 is a major C19-diterpenoid alkaloid isolated from the root extracts of Delphinium sp.…”

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

“…According to X-ray crystal structure analysis, the indolinonepyrrole fragment was bound to the hetisine-type C 20 -DA part through an a-directed (relative to the indoline core) C (17) -C (3 0 ) covalent bond. 98 Vakognavine-type C 20 -DAs (C-2) have an N-C (19) seco hetisine skeleton in addition to a formyl group at C-4. During the past forty years, 17 new vakognavines were isolated from 6 Delphinium species (Fig.…”
