Five steroidal saponins, namely henryiosides A–E ( 1 – 5 ), were isolated from the EtOH extract of the rhizomes of Smilacina henryi. Their structures were elucidated by the extensive use of 1D‐ and 2D‐NMR experiments, along with HR‐MALDI‐MS analysis and the results of acid hydrolysis. The aglycones of henryiosides A–E possess a C(7)C(8) or C(9)C(11) bond and were not previously found in saponins.
