## Abstract Two new C~22~‐steroidal lactone glycosides, ypsilactosides A (**1**) and B (**2**), were isolated from the EtOH extract of the whole plant of __Ypsilandra thibetica.__ Their structures were established as (3__β__,5__α__,16__β__,20__S__)‐3,16‐dihydroxy‐6‐oxopregnane‐20‐carboxylic acid __
## Abstract Five new pregnane glycosides, caradalzielosides A–E (**1**–**5**), were isolated from the aerial parts of __Caralluma dalzielii.__ Their structures were elucidated by extensive 1D‐ and 2D‐NMR spectroscopic analysis as well as by HR‐FAB‐MS experiments.
## Abstract Five new uncommon polyoxygenated steroids, namely suberoretisteroids A–E (**1**–**5**), were isolated from the gorgonian __Suberogorgia reticulata__, never studied so far. The structures and relative configurations of these new compounds were elucidated on the basis of extensive spectra
