Two novel triterpenes, yardenone (5) and abudinol(6) together with the known sodwanones A-D (1 -4) have been isolated from the marine sponge Ptilocaulis spiculifer. The structures of compounds 5 and 6 were determined by interpretation of their 1D and 2D NMR spectra and were secured, including their
Sipholenol and sipholenone, two new triterpenes from the marine sponge siphonochalina siphonella (levi).

β¦ Synopsis
Several squalene-derived
triterpenes possessing a hitherto unknown ring system were isolated from the Red Sea Sponge, Siphonochalinl siphonella.
The structure of one of the new compounds, sipholenol (la), was determined ty spectroscopic methods including a full x-ray diffrac-

Siphonodiol and two related metabolites were isolated from the marine sponge Siphonochalina truncata as H,K-ATPase inhibitors, and their structures including absolute configuration were determined by spectroscopic methods.
