Objective:
To study the chemical constituents of Herpetospermum caudigerum.
Methods:
The chemical constituents were isolated by silica gel, Sephedex LH-20 and MCI methods. Their structures were elucidated by physical-chemical properties and spectroscopic methods such as UV, IR, ESI-MS, H-NMR and 13 C-NMR.
Results:
Seven compounds were isolated and identified as Herpetolide A (1), Herpetolide B (2), Dehydrodiconiferyl alcohol (3), Herpetol (4), Arbutin, 1-acetate (5), Dodecanoic acid (6) and 10-Eicosenoic acid (7).
Conclusion:
compounds 5-7 are isolated from this plant for the first time.
