Limonoids from Trichilia havanensis

Phytochemistry, 1990
Abstract The limonoids of the seeds of Trichilia havanensis were studied in two ripening stages. From the unripened seeds azadirone, havanensin triacetate and three new limonoids were isolated. The mature seeds contained havanesin triacetate and its hydroxy lactone derivative.

New limonoids from the fruits of Melia toosendan and their autophagic activities

, 2020
Limonoids are a kind of bioactive triterpenoids and mainly exist in the Meliaceae and Rutaceae plants. In this research, two new nimbolinin-type limonoids (1 and 2), one new trichilin-type limonoid (3), and one new havanensin-type limonoid (4), along ...

Limonoids of calamondin seeds

Tetrahedron, 1981
Abstract Five new limonoids were isolated from calamondin seeds: methyl deacetylnomilinate (7), calamin (9), retrocalamin (10), cyclocalamin (11), and methyl isoobacunoate diosphenol (13). Structures were assigned on the basis of 1H and 13CNMR spectra, and chemical conversions of 9 to 10, 11, and 13. These reactions are also biogenetically plausible.

Gedunin, ad-seco limonoid

Journal of Chemical Crystallography, 1996
Chloroform/Methanol extraction of the bark ofCedrela salvadorensis (Meliaceae), followed by chromatography afforded the crystalline C28H34O7 terpene. The structure first proposed by spectroscopy is confirmed by this X-ray analysis as 7α-acetyloxy-14,15:21,23-diepoxy-4,4,8-trimethyl-d-homo-24-nor-17-oxachola-1,20,22-triene-3,16,-dione.

Nanodelivery system based on zein-alginate complexes enhances in vitro chemopreventive activity and bioavailability of pomelo [Citrus maxima (Burm.) Merr.] seed limonoids

, 2019
Limonin and nomilin, the major limonoid components of pomelo [Citrus maxima (Burm.) Merr.] seeds, have been reported to be potential cancer chemopreventive agents, but their low aqueous solubility and limited bioavailability impede their applications as ...

Limonoid Bitter Principles

1968
The limonoid bitter principles are a class of C26 degraded triterpenes believed to arise as oxidation products of tetracyclic triterpenes. A second group of related bitter principles, the simaroubolides, occur as further breakdown products in this series (30, 55, 97).
