Plant materials (i.e., leaves, fruits, and seeds) from 40 trees of Azadirachta indica A. Juss. were collected from six different locations across the Colombian Caribbean coast. Eighty-four ethanolic extracts were prepared and the total limonoid contents (TLiC) and the antifungal activity against Fusarium oxysporum conidia were measured. Their chemical profiles were also recorded via liquid
filexlib. Azadirachta Indica A.Juss also known as neem plant is one of the most popular medicinal plants in Asia and They are greenish and biological activities of Azadirachta when ripe and their seeds are ovoid or indica were intensively investigated in both spherical (10). Some of the limonoid compounds isolated from Azadirachta indica.
Three new limonoids, azadiraindins E-G (1-3, respectively), together with six known analogs, were isolated from the fresh fruit coats of Azadirachta indica. Three new limonoids, azadiraindins E-G (1-3, respectively), together with six known analogs, were isolated from the fresh fruit coats of Azadirachta indica. The structures of these compounds were elucidated by spectroscopic methods
Lipids: A. indica oil has long been produced in Asia on an industrial scale for soaps, cosmetics, pharmaceuticals and other non-edible products. The seed oil yield is sometimes as high as 50% of the weight of the kernel. Neem oil is valued at about USD 700/t (1990).

Thirty-one nortriterpenoids, including 28 limonoids (1-28) and 3 degraded limonoids (29-31), and one diterpenoid (32), were isolated from the seed extract of Azadirachta indica (neem). Among these, six were new compounds and their structures were established to be 15-hydroxyazadiradione (3), 7-benzoyl-17-hydroxynimbocinol (5), 23-deoxyazadironolide (12), limocin E (13), 23-epilimocin E (14 Eight limonoids were isolated from 95% ethanol extracts of neem(Azadirachta indica) seeds by various chromatographic methods. By comparison of their spectroscopic data with those reported in the literatures, these limonoids were determined as salannin(1), 1-detigloyl-1-isobutylsalannin(2), salannol- …
A rare spiro-type limonoid spirodione (1) was isolated from the seeds of Azadirachta indica A. Juss.Its structure was elucidated through analysis of the spectroscopic data including HRESIMS, NMR, etc., and the absolute configurations were assigned by comparison of experimental and TDDFT-calculated ECD spectra.

Four new limonoids, together with five known ones, were isolated from dry seeds of neem ( Azadirachta indica A. Juss). Their structures were elucidated by spectroscopic methods and quantum chemical calculation. Compounds 2 and 5 selectively inhibited growth of human cancer cells. 1. Introduction
Three new limonoids, azadiraindins E-G (1-3, respectively), together with six known analogs, were isolated from the fresh fruit coats of Azadirachta indica. The structures of these compounds
The limonoids (triterpenoids), including the natural insecticide azadirachtin, from the seeds of the neem tree (Azadirachta indica) can be partially purified and separated into groups for final analysis very quickly by the use of solid phase extraction procedures. The individual compounds can then be accurately quantified in the separated fractions by supercritical fluid chromatography or high

Abstract Three new limonoids, azadiraindins E-G (1-3, respectively), together with six known analogs, were isolated from the fresh fruit coats of Azadirachta indica. The structures of these compounds were elucidated by spectroscopic methods (IR, MS, HR-ESI-MS, 1D NMR, and 2D NMR).
