Chemical investigation of the ethyl acetate extract of the leaves of Sandoricum koetjape Merr. (Meliaceae) resulted in the isolation of two new limonoids. The compounds have been identified as their corresponding acetate derivatives (1) and (2). The structures have been established as 2α-acyloxysandoricin by analysis of NMR spectral data especially 2D NMR. INTRODUCTION Sandoricum koetjape Merr....
متن کاملChemical constituents from the leaves of Aglaia odorata.
A new dammarane triterpene, 3-acetoxy aglinin C (1), and a new aglain, 10-oxo-aglaxiflorin D (2), along with five known compounds, 3-7, were isolated from the leaves of Aglaia odorata using chromatographic methods. The structures of 1 and 2 were determined on the basis of spectroscopic analyses. Bioactivities of 1-7 against AGZY 83-a (human lung cancer cell line) and SMMC-7721 (human liver canc...
متن کاملChemical constituents from the leaves and stems of Schisandra lancifolia.
A new nortriterpenoid, 20-hydroxymicrandilactone D (1) and a novel lignan glycoside, lancilignanside A (2) were isolated from leaves and stems of Schisandra lancifolia, together with three known nortriterpenoids (3-5) and nine known phenolics (6-14). The structures of new compounds 1 and 2 were determined by detailed analysis of their 1D and 2D NMR spectra, and chemical evidences. In addition, ...
