Antioxidant and cyclooxygenase activities of fatty acids found in food.
There was an increase in antioxidant activity with increasing chain length from octanoic acid to myristic acid (C-8-C-14) and a decrease thereafter, and all unsaturated fatty acids showed good antioxidant activity except for undecylenic acid (12), cis-5-dodecenoic acid, and nervonic acid (29).
Identification and bioactivities of resveratrol oligomers and flavonoids from Carex folliculata seeds.
Given the wide availability and underutilization of C. folliculata, this forage may provide a source of bioactive compounds useful for nutraceutical purposes, and this is the first reported phytochemical investigation of the plant.
Resveratrol oligomers isolated from Carex species inhibit growth of human colon tumorigenic cells mediated by cell cycle arrest.
This study adds to the growing body of knowledge supporting the anticancer effects of resveratrol and its oligomers, and suggests that Carex species should be investigated for their nutraceutical potential given that they produce biologically active stilbenoids such as α-viniferin.
Sensitivity of nonuniform sampling NMR.
These formal results clearly demonstrate the inadequacies of applying US to decaying signals in indirect nD-NMR dimensions, supporting a broader adoption of NUS and introducing the matched NUS SNR Theorem: an exponential sampling density matched to the signal decay always improves the SNR with additional evolution time.
Bioactive acylphloroglucinols from Hypericum densiflorum
All three compounds showed moderate to strong antitumor, antibacterial, antioxidant and inhibition of COX‐2 activities, the first reported occurrence of compound 3 in the Hypericum genus.
Prenylated benzophenone derivatives from Clusia havetiodes var. stenocarpa.
Extracts of the fruit of Clusia havetiodes var. stenocarpa have yielded three new prenylated benzophenone derivatives, 28,29-epoxyplukenetione A (1), 33-hydroperoxyisoplukenetione C (2), and
