Natural antioxidants. II. Antioxidative components isolated from seeds of Plantago asiatica LINNE.

Iridoid and phenolic diglycosides from Canthium berberidifolium

“…Seven were identified as known compounds: geniposidic acid (1) (Guarnaccia et al, 1972;Toda et al, 1985), 4-O-bd-glucopyranosylacetophenone (picein, 3) (Ushiyama and Furuya, 1989) (Wang et al, 1998) (Miyase et al, 1987), koaburaside (8) (Ogawa et al, 1973;Gewali et al, 1988) and hymexelsin (12) (Rao et al, 1988) by comparison of physical data with literature values and from spectroscopic evidence.…”

Effects of Dietary Turmeric Powder on Laying Performance and Egg Qualities in Laying Hens

“…Phenolic compounds act as antioxidant with mechanisms involving both free radical scavenging and metal chelation. They have ideal structural chemistry for free radical-scavenging activities, and have been shown to be more effective antioxidant in vitro than vitamins E and C on a molar basis (Toda et al, 1985).…”

Application of omija (Schiandra chinensis) and plum (Prunus mume) extracts for the improvement of Kimchi quality

“…The total phenol amounts of the omija and plum extracts were 4.6 mg/mL and 19.8 mg/mL, respectively (data not shown). In particular, the omija extract contained a variety of lignans, schizandrin, gomisin N, and gomisin A, all of which were reported to have antioxidants (Toda et al, 1988) and to exert antimicrobial effects (Lee & Lim, 1998). The plum also contained polyphenol compounds and a higher (4.04%) level of organic acids, including citric acid, malic acid, oxalic acid, succinic acid, tartaric acid, fumaric acid, and maleic acid, than were detected in other fruits.…”
