From the MeOH extract of the seeds of Fevillea trilobata (Cucurbitaceae) were isolated fevicordin A glucoside [1], cayaponoside B [2], cayaponoside D [3], a new norcucurbitacin glucoside, and a new heptanorcucurbitacin glucoside. The structure of the new norcucurbitacin glucoside, andirobicin A glucoside, was established as 29-nor-1,2,3,4,5,10-dehydro-25-methoxy-2-O-beta-D-glucopyranosyl- 3,16 alpha,20R,22 xi-tetrahydroxy-11-oxocucurbit-23-ene [4], and that of the novel heptanorcucurbitacin… 
A new dammarane saponin and other triterpenoids from Siolmatra brasiliensis and evaluation of the antidiabetic activity of its extract
The known cucurbitacins and/or the new identified saponin may be related with the antidiabetic activity of S. brasiliensis.
Tetracyclic triterpenes. Part 16. Synthesis of 31-norcucurbitane and fusidane derivatives in the skeletal rearrangements of 9,11-epoxy-4β-demethyl-5α-lanostanes
The BF3·Et2O-catalysed rearrangement of 9β,11β-epoxy-4β-demethyl-5α-lanostan-7-one derivatives 11 and 12 in acetic anhydride resulted in formation of 19(10→9β)abeo compounds (31-norcucurbitanes)
Cucurbitacins and cucurbitane glycosides: structures and biological activities.
The natural cucurbitacins constitute a group of triterpenoid substances which are well-known for their bitterness and toxicity and are divided into twelve categories.
Naturally occurring aromatic steroids and their biological activities
The role of aromatic steroids is emphasized as an important source and potential leads for drug discovery and they are of great interest to chemists, physicians, biologists, pharmacologists, and the pharmaceutical industry.
