AI Article Synopsis
- Two new glycosidic acids, calyhedic acids E and F, were isolated from a resin glycoside fraction derived from whole plants of a specific species.
- Their structures were determined to be complex glycosides with multiple sugar units, specifically characterized by a long hydrocarbon chain with hydroxyl groups.
- The identification of these compounds was based on detailed spectroscopic analysis, revealing structural differences between acids E and F.
Article Abstract
Two new glycosidic acids, calyhedic acids E () and F (), were isolated from the glycosidic acid fraction afforded by alkaline hydrolysis of the crude resin glycoside fraction obtained from whole plants of Wall. Compounds and were characterised as 11-hydroxyhexadecanoic acid 11--β-D-glucopyranosyl-(1→6)--β-D-glucopyranosyl-(1→6)--β-D-glucopyranosyl-(1→3)-[-α-L-rhamnopyranosyl-(1→2)]--β-D-glucopyranosyl-(1→2)-β-D-quinovopyranoside and an isomer of , in which the 11-hydroxyhexadecanoyl residue of was replaced by a 12-hydroxyhexadecanoyl residue, respectively, on the basis of spectroscopic data.

Light-emitting diode (LED) lamps are efficient elicitors of secondary metabolites. To investigate the influence of LED light on steviol glycosides (SGs) and phenolic compounds biosynthesis, stevia shoots were cultured under the following LED lights: white-WL, blue-B, red-R, 70% red and 30% blue-RB, 50% UV, 35% red and 15% blue-RBUV, 50% green, 35% red and 15% blue-RBG, 50% yellow, 35% red and 15% blue-RBY, 50% far-red, 35% red and 15% blue-RBFR and white fluorescent light (WFl, control). RBG light stimulated shoots' biomass production.
