Abstract Two new limonoids, trichilinin M ( 1 ) and ohchinin benzoate 2 ), along with two known 12‐hydroxyamoorastatone 3 mesendanin H 4 were isolated from the fruits of Melia azedarach Linn. The structures limonoids determined by analyses HR‐ESI‐MS, 1D 2D NMR (HSQC, HMBC NOESY) data. All compounds evaluated against human pancreatic cancer PANC1 cells results showed that – exhibited substantial cytotoxic activity : IC 50 =4.55 μM; =7.54 μM), moderate cytotoxicity =27.06 =21.17 μM).
A phytochemical investigation of Bidens procera L.C.Xu ex X.W.Zheng afforded two novel polyacetylenes, tridecane-2E-monoene-4,6,8-triyntylen-1,13-diol-12-O-β-glucoside (1) and tetradecane-2E,8E-diene-4,6-diyne-1,14-diol-13-O-β-glucoside (2), together with ten known compounds (3 − 12). Their chemical structures were elucidated by NMR MS spectrums as well the comparison published data. Furthermore, chemotaxonomy yielded was also discussed.
The present work was undertaken to investigate chemical constituents and chemotaxonomic significance from the seeds of Raphanus sativus L. As a result, sixteen compounds including sinapoyl derivatives ( 1-7 ) indoles 8-16 were yielded, their structures elucidated by 1 H NMR 13 C spectroscopic methods, along with comparison relevant literature data. Of note, ethyl 2,3-dihydro-2-oxo-1H-indole-3-acetate (compound 11 new natural product. Three 12 , 16 first isolated genus ; while five 5 9 10 14,...
Abstract The bromo ester (I) is coupled with the phenols (II) to produce corresponding α‐phenoxy esters (III) which are transformed into imidazolines (V) mentioned in title by cyclocondensation diamines (IV).
