Chemical investigations of the aerial parts of Tibetan folk medicine Delphinium chrysotrichum resulted in the isolation of two new diterpenoid alkaloids, delphatisine D (1) and chrysotrichumine A (2), together with ten known diterpenoid alkaloids (3-12) and 3β,6α-dihydroxysclareolida (13).
Diterpenoid alkaloids with remarkable chemical properties and biological activities are frequently found in plants of the genera Aconitum, Delphinium, and Garrya. Accordingly, several C19-diterpenoid alkaloid components from Delphinium elatum cv. Pacific Giant, as well as their derivatives,
Five hetisane-type C20-diterpenoid alkaloids, trichodelphinines A-E, one delnudine-type C20-diterpenoid alkaloid, trichodelphinine F and three known flavonoids, quercetin, quercetin 3-O-β-D-glucopyranoside, and quercetin 3-O-β-D-glucopyranoside-7-O-α-L-arabinopyranoside, were isolated from whole
Five new C18-diterpenoid alkaloids, anthriscifoltines C-G (1-5), along with four known diterpenoid alkaloids anthriscifolcines C-F (6-9), were isolated from the extract of Delphinium anthriscifolium var. majus. Their structures were elucidated by extensive spectroscopic analyses (including 1D-,
Extensive phytochemical investigation on the whole herbs of Delphinium anthriscifolium var. majus led to the identification of fourteen diterpenoid alkaloids, including three new C20-diterpenoid alkaloids (anthriscifolsines A-C, 1-3), six new C19-diterpenoid alkaloids (anthriscifolrines A-F, 4-9),
Five new diterpenoid alkaloids, tianshanitines A-E (1 - 5), along with ten known compounds (6 - 15), were isolated from the EtOH extracts of the whole plant of Delphinium tianshanicum W.T.Wang. Their structures were determined based on extensive spectroscopic analyses, including 1D- and 2D-NMR,
Eight previously undescribed norditerpenoid alkaloids, pseudophnines A-D, pseudorenines A-B, and pseudonidines A-B, together with ten known norditerpenoid alkaloids, tianshanisine E, sharwuphinine B, potanisine A, lycoctonine, delbruline, isondelpheline, delavaines A-B, and shawurenines A-B were
