• A modification of the Koenigs-Knorr reaction for building glycosides from 2, 3, 4, 6-tetra-O-acetyl-?-D-glucopyranosyl bromide ( acetobromoglucose ) originates from S . Hanessian who used the silver salt silver trifluoromethanesulfonate ( TfOAg ) and as a proton acceptor tetramethylurea.
• Separation of the active ingredients from diarylheptanoids and phloracetophenone glucoside compounds were carried out and some active compounds, such as 1, 7-diphenyl-5-hydroxy-( 1E )-1-heptene and 4, 6-dihydroxy-2-o-( b-D-glucopyranosyl ) acetophenone, were found to have a stimulative effect on bile secretion in rats.

• Fermentation of ginsenoside Rb ( 1 ) with " A . strictum " yields three new compounds  12?-hydroxydammar-3-one-20 ( S )-O-?-D-glucopyranoside, 12?, 25-dihydroxydammar-( E )-20 ( 22 )-ene-3-O-?-D-glucopyranosyl-( 1?! 2 )-?-D-glucopyranoside, and 12?, 20 ( R ), 25-trihydroxydammar-3-O-?-D-glucopyranosyl-( 1?! 2 )-?-D-glucopyranoside  as well as five known compounds  ginsenoside Rd, gypenoside XVII, ginsenoside Rg, ginsenoside F, and compound K . Many of these compounds are metabolites of ginsenoside Rb ( 1 ) in mammals, suggesting that fermentation of ginsenoside Rb ( 1 ) in " A . strictum " may be similar to mammalian metabolism and may be a useful agent for generating specific metabolites or related ginsenoside analogs, which can be later isolated for structural elucidation and use in pharmaceutical research.
