This study was aimed to determine the qualitative and quantitative phenolic compounds. Results revealed that HPLC analysis identified Hydroxy derivatives of benzoic acids, hydroxy-cinnamic in addition flavonoids. The major compounds detected clove were eugenol 32.5 mg/L, while thyme predominant phenol gallic acid 35.9 mg/L. Quercetin greatest compound both eucalyptus sage 49.8 55.6 respectively...

Effects on wool growth rate of abomasal supplements of several amino acids (glycine, glutamic acid, arginine, lysine, and threonine) and of some sulphurcontaining compounds (L-cysteamine, sulphuric acid, and methionine hydroxy analogue) were examined. None of the abomasal supplements, apart from methionine hydroxy analogue, was effective for stimulating wool growth. Methionine hydroxy analogue ...

Thirteen undescribed 24-methylene lanostane triterpenoids, named polyporenic acids E-M and fomitosides L-O, as well seventeen known analogues, were isolated from the fruiting bodies of mushroom Fomitopsis betulina. Their structures determined using 1D, 2D NMR, IR, HRESIMS. Fomitoside L fomitoside N exhibited cytotoxicity against HL60 leukemia cells (IC50 = 15.8 23.7 ?M, respectively). Among com...

Phosphonodepsipeptides are phosphorus analogues of depsipeptides and phosphonate-linked naturally occurring peptides. They more stable than phosphonopeptides have been widely applied as enzyme inhibitors, haptens for the production antibodies, biological agents, prodrugs. The synthetic strategies towards phosphonodepsipeptides reviewed, including phosphonylation hydroxy esters with phosphonochl...

The chemical nature of the royal jelly (RJ) has received considerable attention over the past 20 years. Genc and Aslan reported the determination of Trans-10-hydroxy-2-decenoic acid (10-HDA) content in pure Royal Jelly and royal jelly products by column liquid chromatography. Antinelli et al. confirmed this method and evaluated 10-Hydroxy-2-decenoic acid presence as a freshness parameter for Ro...

A new method for the detection and estimation of long-chain epoxy acids in seed oils is described. It depends on the measurement of increased absorption at 2.795 p in the near infrared spectrum caused by chlorohydrins produced from epoxides by treatment with anhydrous ethereal hydrogen chloride. The method is sensitive to approximately 0.2% of epoxy acid in an oil and is specific for epoxides. ...

Cyclodepsipeptides comprise a unique class of secondary metabolides. They frequently contain unusual amino acids, like d-amino acids or N-methylated amino acids and hydroxy acids that typically originate from the polyketide pathway. Incorporation of the hydroxy acid results in an ester bond, explaining the term “depsi”. Many cyclodepsipeptides have been isolated from marine sponges and found to...
