A new tropane alkaloid as well as a new substitution group, (3‐ endo ,8‐ anti )‐8‐methyl‐8‐azabicyclo[3.2.1]oct‐3‐yl 4‐hydroxy‐3,5‐dimethoxybenzoate, called pungencine ( 1 ), was isolated from the roots of Erythroxylum pungens O. E. Schulz . The structure was elucidated by spectral analyses, including 1 H‐ and 13 C‐NMR and 2D‐NMR techniques ( 1 H, 1 H‐COSY, NOESY, DEPT, HMQC, and HMBC) and HR‐ESI‐MS. Furthermore, compound 1 was tested for cytotoxicity against several cell lines (Jurkat, HL‐60, U937, K562, KG‐1, and U266) and was determined not to inhibit cell viability at 10 μ M .
