fumarates and ferulic-acid

Phenolics play a key role in communication between plants and microbes in the rhizosphere. In this study, shikimic, gallic, fumaric, ferulic, vanillic acid and quercetin in root exudates of Abelmoschus esculentus act as chemoattractants of endophytic Alcaligenes faecalis strains, BHU 12, BHU 16 and BHU M7. In vitro chemotaxis assay showed that BHU 12 expressed highest chemotactic movement (CFU ∼50×10

The compound excipient containing sodium stearyl fumarate and plasdone S-630 was prepared by applying spray drying method. The basic physical properties of compound excipient were studied by solubility test, scanning electron microscope, differential scanning calorimeter, X-ray diffraction and Fourier transform infra-red spectroscopy. The effect of compound excipient on moisture absorption and ferulic acid in vitro dissolution of spray drying power of angelica were investigated. The results showed that the chemical constituents of compound excipient did not change before and after spray drying. The water soluble compound excipient can improve significantly moisture absorption and has application prospect.
