- Abstract:
- ... Two novel phenols, alashinols I and J (1a and 1b), which are enantiomers, were isolated from the stem bark of Syringa pinnatifolia and possess unusual carbon skeletons. The structures were elucidated based on NMR and MS data analyses, and their absolute configurations were assigned by ECD calculations. Additionally, 1a and 1b were moderately effective at inhibiting oxidative stress-induced injury ...

- Abstract:
- ... The plant Morinda parvifolia is traditionally used as an herbal medicine for the treatment of dyspepsia, tracheitis, and coughing. The ethyl acetate extract of the aerial parts of M. parvifolia showed significant inhibition against ear edema in mice induced by croton oil (36.4% inhibition). Four undescribed glycosides, 2-hydroxymethyl anthraquinone-3-O-β-primeveroside, p-hydroxy benzoic acid 4-O-β ...
