Discovery of Diverse Polycyclic Polyprenylated Acylphloroglucinols from Hypericum kouytchense with Anti-Liver Fibrosis Potential
Hypercoretions A–C (1–3), three types of unprecedented polycyclic polyprenylated acylphloroglucinols (PPAPs), were isolated from Hypericum kouytchense using a combined FBMN and UV-guided isolation method. Notably, hypercoretion A (1) represents a unique nor-PPAP characterized by a rearranged 5/6/6/5 tetracyclic skele...
