General description
Vanillin is a flavor and fragrance compound, found as a major constituent of natural vanilla. It′s of commercial importance in both food and non-food applications and pharmaceutical preparations. It′s well-known as an intermediate in the synthesis of herbicides, antifoaming and antimicrobial agents.
Mettler-Toledo calibration substance ME 51143093, vanillin is an analytical standard for use in the regular checking of Mettler-Toledo melting point instrument. Its value equals an average of 6 to 12 measurements with a Mettler-Toledo MP90 Excellence instrument that is calibrated against primary standards. The melting point is validated by Capillary method according to European Pharmacopeia (2.2.14.)

Two new sesquiterpene coumarins, designated 5'-acetoxy-8'-hydroxyumbelliprenin (1) and 10'R-acetoxy-11'-hydroxyumbelliprenin (2), and a new diterpene, 15-hydroxy-6-en-dehydroabietic acid (3), along with 27 known compounds, were isolated from a CHCl(3)-soluble extract of Ferula assa-foetida through bioassay-guided fractionation. The structures of the new metabolites

Overproduction of a desired metabolite is often achieved via manipulation of the pathway directly leading to the product or through engineering of distant nodes within the metabolic network. Empirical examples illustrating the combined effect of these local and global strategies

Bioassay-guided fractionation led to the isolation of six new tetrahydroflavanones, cryptochinones A-F (1-6), from the neutral CHCl(3) fraction of Cryptocarya chinensis leaves, together with 14 known compounds (7-20). The structures of these new compounds were determined through spectroscopic analyses, including
