 Title    Polyphenols in Stachys and Betonica Species (Lamiaceae) Fax: 0 0 3 5 9 2 -7 0 0 -2 2 5 . E-mail: iochnp@bgcict  
 Abstract    Above-ground parts and roots from four Stachys species (S. germanica L., S. sylvatica L. and the Balkan endemics S. thracica Dav. and S. plumosa Griseb.) as well as o f three Betonica species (B. officinalis L. and the Balkan endemics B. bulgarica Deg. et Neic. and B. scardica Griseb.) were screened for phenols (phenylethanoid glycosides, flavonoid glycosides and the phenolic diterpene betolide). Three phenylethanoid glycosides, a flavonoid glycoside and the phenolic diterpene betolide were isolated and identified, most of them for the first time in the investigated species. The results obtained support the view that Stachys and Betonica are well separated genera.

 Title    Sterol Composition of the Black Sea Sponges Hymeniacidon sanguinea (Grant) and Halichondria panicea (Pallas)  
 Abstract    The sterol composition of H ym eniacidon sanguinea and H alichondria panicea from the Black Sea was investigated. Both sponges contain similar mixtures o f stan d s and o f dietary A5-sterols. Main sterols appeared to be C27-sterols, which could be connected with a common diet for the both sponges. Saturated short side chain sterols have been found in H ym eniaci­ don sanguinea. Three of them were novel for sponges. A possibility for the transformation of som e dietary sterols into stands is discussed.

 Title    Bromoisoxazoline Alkaloids from the Caribbean Sponge Aplysina insularis  
 Abstract    An investigation of a specimen of the Caribbean sponge A plysina insularis resulted in the isolation of fourteen bromoisoxazoline alkaloids (1 -1 4), of which 14-oxo-aerophobin-2 (1)* is a novel derivative. Structure elucidation of the compounds have been established from spectral studies and data for 1 are reported. Constituents 2 to 6 and 11 to 14 have not been identified sofar in A plysina insularis species. The presence of the known compounds 7 to 9 in A plysina insularis indicates that their use for chem otaxonom ical purposes is questionable.
