, p. 637 - 641 (2016/09/03)
Two new iridoid glycosides, algidiside I [2′-(2′′,3′′-dihydroxybenzoyl)loganic acid] (1) and algidiside II [6′-(2′′,3′′-dihydroxybenzoyl)loganic acid] (2), and 14 known iridoids including for the first time from the aerial part of Gentiana algida Pall. 2′

The activity of 7-deoxyloganin 7-hydroxylase, an enzyme catalyzing the conversion of 7-deoxyloganin into loganin, was detected in a microsomal preparation from the cell suspension cultures of Lonicera japonica. It was dependent on NADPH and molecular oxyg
Iridoid glucosides from Picconia excelsa
Damtoft, Soren,Franzyk, Henrik,Jensen, Soren Rosendal
, p. 743 - 750 (2007/10/03)
An investigation of the iridoids of Picconia excelsa from Tenerife provided 17 iridoid glucosides together with verbascoside. Major constituents (> 0.5%) were loganin, ketologanin, oleoacteoside and the new picconioside I- a bisiridoid consisting of loganin esterified with deoxyloganin. Minor constituents were secoxyloganin, 8-epi-kingiside, oleoside 11-methyl ester, excelsioside, ligstroside and loganic acid together with the new compounds ketologanic acid, 6β-hydroxy-7-epi-loganin and picconiosides II-V, the latter four being esters of loganin and menthiafolic, foliamenthic, 6-(Z)- foliamenthic or 6,7-dihydrofoliamenthic acid. The structures were mainly elucidated by NMR spectroscopy.
