Limonoids from the stem bark of Cedrela odorata

Phytochemistry, 2008
Four nomilin/obacunol derivatives and a swietenolide derivative, together with seven known limonoids, were isolated from stem bark of Cedrela odorata and their structures established by spectroscopic methods. Antifeedant activity of the isolated compounds was also tested.

Extractives of Cedrela odorata L.—III

Tetrahedron, 1969
Abstract An extract of Cedrela odorata L. has given a non-furanoid tetranortriterpene. This is shown to be closely related to gedunin with the furan ring modified as a γ-hydroxy α,β-butenolide.

Cedrela odorata (Spanish cedar).

2021
Abstract C. odorata is a large tree up to 40 m tall and 2 m in diameter which produces a light-weight timber. Its natural distribution range is confined to the New World, extending from northern Mexico to Argentina, including the Caribbean. It is widely planted throughout the tropics and its timber is well known for its use in cigar boxes and a

Dendroecological Studies with Cedrela odorata L., Northeastern Brazil

2020
Northeastern Brazil is home to the Caatinga Forest, characterized as a Tropical Dry Forest (TDF), and the Dense Ombrophilous Forest (the Atlantic Forest) predominates near the coast. In the Caatinga, the climate is semiarid, with

Extractives from the seed of Cedrela odorata L.

Phytochemistry, 1968
Abstract The seed of Cedrela odorata has been examined and found to contain the known limonoids mexicanolide, andirobin and 6-deoxy swietenolide, together with a new compound which has been identified as 6-hydroxy mexicanolide.

Shoot Damage Effects on Starch Reserves of Cedrela odorata

Biotropica, 1995
The effects of shoot damage on starch concentrations in large roots and lower boles of the tropical timber tree, Cedrela odorata, were measured over a 30-day period following mechanical shoot removal. The degree of damage was based on amounts typically destroyed by Hypsipyla grandella, a serious lepidopteran pest of C. odorata.

Rheological properties of Cedrela odorata gum exudate aqueous dispersions

Food Hydrocolloids, 2009
Abstract Rheological studies of Cedrela odorata gum aqueous dispersions demonstrated viscoelastic properties. Mechanical spectra derived from small amplitude oscillatory shear (SAOS) results support the onset of gel-like structure at given conditions (10% w/v, 20 °C). The increase in the storage and loss moduli, along with the drop in their frequency

Extractives from Cedrela odorata L. The structure of methyl angolensate

Journal of the Chemical Society C: Organic, 1967
The constituents of the heartwood of Cedrela odorata are variable. The structure of methyl angolensate, one of the components, is elucidated on the basis of spectroscopic evidence and chemical transformations. It is a secoring-B tetranortriterpenoid closely related biogenetically to gedunin and deacetyl-7-keto-gedunin, which are also found in the ...

Extractives of Cedrela odorata L. Part II. The structures of the Cedrela tetracyclic triterpenes, odoratol, iso-odoratol, and odoratonen

Journal of the Chemical Society C: Organic, 1968
Three triterpenes have been isolated from Cedrela odorata L. These are shown by chemical and spectroscopic evidence to be derivatives of tirucallol in which the side chain has been modified to a dihydroxytetrahydrofuran.

Chemical Composition of the Bark Oil ofCedrela odoratafrom S. Tomé and Príncipe

Journal of Essential Oil Research, 2003
Abstract The essential oil of Cedrela odorata L. bark from S. Tome and Principe, where this plant is used in traditional medicine mainly for the treatment of malaria as well as a febrifuge and against diabetes, was investigated for the first time. The oil was obtained by hydrodistillation of the bark, and subsequently analyzed by GC, GC/MS and 13C-NMR.
