Isolation, characterization, and docking studies of campesterol and β-sitosterol from Strychnos innocua (Delile) root bark

J‐filter: An experiment to simplify and isolate specific signals in 1H NMR spectra of complex mixtures based on scalar coupling constants

“…However, the 1D proton spectrum shows a complex mixture of sterols, and there is signal crowding in the relevant region of the methyl groups from 0.7 to 0.9 ppm (see Figure S2 and Table S1). [22][23][24] The 1D J-filter experiments of Figure 3 allowed us to discern and confidently assign the methyl signal H-29 of β-sitosterol. The J-filter-GEMSTONE of Figure 3b was calibrated by the pseudo-2D spectrum of Figure S3 to select the triplet of H-29 and simultaneously null the signals of other overlapping peaks with the same magnitude of their scalar couplings.…”

Phytochemical Analysis of Anacamptis coriophora Plant Cultivated Using Ex Vitro Symbiotic Propagation

“…At the same time, phytochemicals such as (Z)-7-Hexadecenal at a rate of 0.45 % were determined in the ethyl acetate root bark extract of Strychnos innocua. [72] 2,2-dimethoxybutane is a colorless liquid that is insoluble in water but soluble in organic solvents. It has been shown to be toxic.…”

“…The compound (Z)‐7‐Hexadecenal was detected only in P. platycephala seed extracts. At the same time, phytochemicals such as (Z)‐7‐Hexadecenal at a rate of 0.45 % were determined in the ethyl acetate root bark extract of Strychnos innocua [72] …”

Diatom-guided bone healing via a hybrid natural scaffold

“…To further enhance bone healing effects, β-sitosterol (BS), a natural phytosterol structure like cholesterol, imparts angiogenic, antioxidant, anti-inflammatory, antimicrobial, and anti-osteoporosis activities [ [50] , [51] , [52] , [53] , [54] ].…”
