Regional chronologies of Cedrela fissilis and Cedrela angustifolia in three forest types and their relation to climate

Trees - Structure and Function, 2016
Although tree-ring chronologies of Cedrela fissilis and Cedrela angustifolia showed a common climatic signal, local conditions influence growth, suggesting that forest guidelines should be appropriate to the species and context ...

Breeding Strategy for the Cedrela Genus in Argentina

2020
Three species from the Yungas (Cedrela balansae, C. angustifolia, C. saltensis) and one from the Alto Parana Rainforest (C. fissilis) represent the genus in Argentina. In this chapter, we present the state-of-the-art in their domestication, including afforestation experiences in block and in enrichment strips.

Triterpenes from Cedrela odorata

Phytochemistry, 1991
Abstract From the ethanolic extract of the heartwood of Cedrela odorata were isolated gedunin, 3β- O -β- d -glucopyranosyl-24-methyllenecholesterol, oleanonic acid, sitosterol, n -octacosanol and a new triterpene threo -23,24,25-trihydroxytirucall-7-en-3-one. Structural determinations of these compounds were made by spectrometric data.

Chemical investigation of Cedrela toona

Phytochemistry, 1971
Abstract Two varieties of Cedrela toona Roxb. are available in West Bengal and the seeds of one variety produces cedrelone, 1,2-dihydrocedrelone, bergapten and β-sitosterol. Occurrence of 1,2-dihydrocedrelone, a new tetranortriterpenoid, provides further interesting evidence of the chemotaxonomic feature of Meliaceae .

Triterpenoids from Cedrela sinensis

Tetrahedron, 2005
Abstract Twenty-three new triterpenoids ( 1–23 ), all having an apotirucallane skeleton, were isolated from the seeds, leaves, and stems of Cedrela sinensis (Meliaceae). Their structures were determined by 2D NMR experiments, X-ray crystallographic analysis, and chemical methods.

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

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.
