Abstract: This paper describes the chemical structure elucidation of the three new alkaloids isolated from Pachysandra axillarls Franch. They are pachysamine G (20α-dimethylamino-3β-tigloylamino-5α-pregnane), pachysamine H (20α-dimethylamino-3α-N-methyl, benzoylamino-5α-pregnane) and pachysanaximine A (20 α-dimethylamino-3β-methylamino-4β-benzoxyl-5α-pregnane) respectively. Other two compounds were identified as Pachysamine A, B.

Key words: Pachysandra axillaris Franch., Steroidal alkaloids, Pachysamine G, H, Pachysanaximine A
