Structural elucidation of new ferulic acid-containing phenolic dimers and trimers isolated from maize bran
Four new phenolic dimers and trimers that contain ferulic acid moieties were isolated from the alkaline hydrolyzate of insoluble maize bran fiber and their structures were established by 1D/2D NMR and mass spectrometry. The biological role of one dimer remains unclear whereas the dimeric vanillin-ferulic acid-cross-product probably represents an oxidative degradation product from the correspond...
متن کاملGilvocarcins, new antitumor antibiotics. 2. Structural elucidation.
Gilvocarcin V(1), C27H28O9, m.p. 264 approximately 267 degrees C (dec.), and gilvocarcin M(2), C26H26O9, m.p. 245 approximately 248 degrees C (dec.), are new antitumor antibiotics produced by Streptomyces gilvotanareus. The structure of gilvocarcins has been determined by chemical degradation, nmr and mass spectra. They have a benzonaphtopyran-one system, to which the furanose moiety is linked ...
متن کاملStructural elucidation of a novel phosphoglycolipid isolated from six species of Halomonas.
The structure of a new phosphoglycolipid from the halophilic Gram-negative bacteria Halomonas elongata ATCC 33173(T), Halomonas eurihalina ATCC 49336(T), Halomonas almeriensis CECT 7050(T), strain Sharm (AM238662), Halomonas halophila DSM 4770(T), and Halomonas salina ATCC 49509(T) was elucidated by NMR and mass spectroscopy studies. In all of the species examined, the polar lipid composition c...
متن کاملElucidation of in-vitro anti-inflammatory bioactive compounds isolated from Jatropha curcas L. plant root
BACKGROUND The Jatropha curcas plant or locally known as "Pokok Jarak" has been widely used in traditional medical applications. This plant is used to treat various conditions such as arthritis, gout, jaundice, wound and inflammation. However, the nature of compounds involved has not been well documented. Hence, this study was conducted to investigate the anti-inflammatory activity of different...
متن کاملIsolation of antimicrobial compounds from guava (Psidium guajava L.) and their structural elucidation.
Four antibacterial compounds were isolated from leaves of guava (Psidium guajava L.), and the structures of these compounds were established on the basis of chemical and spectroscopic evidence. Two new flavonoid glycosides, morin-3-O-alpha-L-lyxopyranoside and morin-3-O-alpha-L-arabopyranoside, and two known flavonoids, guaijavarin and quercetin, were identified. The minimum inhibition concentr...
