Studies on the Chemical Constituents of

Azadirachta indica A. Juss (Meliaceae) is indige­ nous to the Indo-Pakistan subcontinent and its various parts are reputed as therapeutic agents [2, 3]. Some of the constituents of neem have recently been shown to possess significant pesticidal activity [4]. More recent studies undertaken on the fresh, un­ dried, uncrushed, ripe and unripe, fruits and the un­ dried leaves of the plant by Siddiq...

Chemical Constituents Isolated from Leaves of Barleria

Two phenolic compounds (PCoumaric acid and α–Tocopherol), two flavonoidal compounds ( luetoline and 7-methoxy luetoline) and two iridoidal glycosides (barlerin and schanshiside methyl ester) have been isolated from leaves of Barleria cristata their structure were established by spectral analysis. This is the first report of occurrence of these compounds from Barleria cristata Linn plant. K. HEM...

Chemical constituents and biological studies of the leaves of Grevillea robusta.

Three new compounds: Graviquinone (1), cis-3-hydroxy-5-pentadecylcyclohexanone (2), and methyl 5-ethoxy-2-hydroxycinnamate (3), and thirty-eight known compounds were isolated and identified from the leaves of Grevillea robusta. The structures of these compounds were determined by spectroscopic and chemical transformation methods. Graviquinone (1) showed the strongest cytotoxicity against MCF-7,...

Chemical Constituents from the Leaves of Sandoricum koetjape

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....

Chemical 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...
