The inhibitory effect of (-)-, (+)-matairesinol and (-)-, (+)-secoisolariciresinol on the discoloration of dark muscle (chiai in Japanese) of two-year-old yellowtail (hamachi in Japanese) was evaluated by measuring the X and a(*) values. (-)-Matairesinol was most effective for retaining the red color of dark muscle in this experiment.
Hinokinin is a lignan isolated from several plant species that has been recently investigated in order to establish its biological activities. So far, its cytotoxicity, its anti-inflammatory and antimicrobial activities have been studied. Particularly interesting is its notable anti-trypanosomal activity.
Linum spp. (Linaceae) has been shown to accumulate cytotoxic lignans such as podophyllotoxin and 6-methoxypodopyllotoxin. Therefore, plant cell and tissue cultures of Linum spp. may be possible alternative sources for the lignan production. In this study, we focused on the production of lignans by root cultures of Linum spp. Hairy root cultures of L. nodiflorum, L.album and L. austriacum and ro...
Five new lignans, ovafolinins A-E (1-5), were isolated from the wood of Lyonia ovalifolia (Ericaceae). The structures of 1-5 were elucidated based on 2D NMR spectroscopy, X-ray crystallography, and other chemical methods.
The paper presents a modified and universally applicable diagnostic fragment-ion-based extension strategy (DFIBES) to efficiently process the information acquired by liquid chromatography-electrospray ionization source in combination with hybrid ion trap and high-resolution time-of-flight mass spectrometry [LC-(ESI)-IT-TOF/MS], facilitating the structural determination of serial components cont...
