Limonoids from Ekebergia capensis

Phytochemistry, 1998
Abstract The hexane extract of the seed of Ekebergia capensis (Meliaceae) yielded the novel limonoids, capensolactones 1–3 and the previously isolated methyl 3α-hydroxy-3-deoxyangolensate. Structures were determined by 2D NMR, mass spectroscopy and chemical methods.

Natural limonoids protect mice from alcohol-induced liver injury

Journal of Basic and Clinical Physiology and Pharmacology, 2020
Background Alcoholic liver disease (ALD) is regarded as a global health problem with limited therapeutic options. Previous studies highlighted some anticancer, antiviral, and hepatoprotective activities of limonoids, but the effects of these compounds on

MS diagnostic model and rapid distinguishing of bioactive limonoids in fruits of Melia toosendan using solid-phase extraction coupled with LC-MS/MS.

Phytochemical Analysis, 2020
INTRODUCTION Melia toosendan Sieb. et Zucc. has been used as a Chinese folk medicine for roundworm treatment since ancient times. Many diverse limonoids have been isolated from Meliaceae plants, but it remains difficult to isolate and identify other ...

Limonoids from Aphanamixis polystacha

Phytochemistry, 1999
The hexane extract of the seed of Aphanamixis polystacha (Meliaceae) has yielded kihadalactone A and three novel limonoids, rohituka-12, rohituka-13 and rohituka-14. The substitution at C-1 of polystachin has been re-assigned as α.

Limonoids from Trichilia hirta

Phytochemistry, 1992
Abstract From the fruits and leaves of Trichilia hirta were isolated, besides sitosterol and sitostenone, two novel limonoids: methyl 11β-acetoxy-6-hydroxy-12α-(2-methylpropionyloxy)-3,7-dioxo-1,5,14,20,22-meliacapentaen-29-oate and methyl 11β-acetoxy-6,23-dihydroxy-12α-(2-methylpropionyloxy)-3,7,21-trioxo-1,5,14,20-meliacatetraen-29-oate.

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.

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.
