Limonoid glucosides in citrus

Phytochemistry, 1989
Abstract Citrus contained high concentrations of limonoid glucosides. Four new glucosides, isolated from grapefruit seeds, were identified as limonin 17- O -β- d -glucopyranoside, nomilin 17- O -β- d -glucopyranoside, deacetylnomilin 17- O -β- d -glucopyranoside and obacunone 17- O -β- d -glucopyranoside.

A limonoid from Trichilia estipulata

Phytochemistry, 2000
The limonoid 21,24,25,26,27-pentanor-15,22-oxo-7alpha,23-dihydroxy-apotirucalla(eupha)-1-en-3-one was isolated from the dichloromethane extract of the stem bark of Trichilia estipulata. Its structure was established by spectroscopic methods (UV, EIMS, 1H and 13C NMR, HMQC and HMBC).

Limonoids of Teclea ouabanguiensis

Journal of Natural Products, 1986
The stem bark of Teclea ouabanguiensis has yielded six triterpenoids, two of which are new. The known compounds were identified spectroscopically as 7-deacetylazadirone (2), 7-deacetylproceranone (3), tecleanin, (4), and lupeol. The novel compounds include the tetranortriterpenoids, 7-deacetoxy-7-oxoazadirone (1), and ouabanginone (5).
