The Structures of Four New Diterpenoid Alkaloids from Delphinium Bonvalotti Franch

Diterpenoid Alkaloids from Delphinium ajacis and Their Anti‐inflammatory Activity

“…In addition, six known clerodane diterpenoids, delectine (4), [20] anthranoyllycoctonine (5), [21] andersonidine (6), [22] delaja- Figure 3. Key 1 H-1 H COSY, HMBC and NOESY correlations of 2. cirine ( 7), [23] ajacine (8) [23] and 14-acetyldelcosine (9) [24] were identified by comparison of their NMR data with literature data. Compounds 1-9 underwent rigorous testing for their antiinflammatory properties, specifically targeting the inhibition of NO production in LPS-induced BV2 cells.…”

“…Nineteen known compounds were identified as majusine B ( 3 ), [14] tongoline (4 ), [15] 8‐methyllycoctonine ( 5 ), [16] delvestidine ( 6 ), [17] 14‐deacetylambiguine ( 7 ), [18] ambiguine ( 8 ), [19] delbotine ( 9 ), [20] delbonine ( 10 ), [21] delphatine ( 11 ), [22] lycoctonine ( 12 ), [22] browniine ( 13 ), [23] delcosine ( 14 ), [19] 14‐acetylbrowniine ( 15 ), [22] tricornine ( 16 ), [22] 14‐benzoylbrowniine ( 17 ), [24] 14‐dehydrobrowniine ( 18 ), [23] anthranoyllycoctonine ( 19 ), [22] acoseptine ( 20 ), [25] dictyzine ( 21 ) [26] through comparing with the spectral data in the literature. All the compounds were isolated from D. liangshanense for the first time.…”
