Biosynthesis of limonoids in Citrus
Phytochemistry, 1977Limonoids represent a group of chemically related triterpenes found in the Rutaceae and Meliaceae. Bitterness due to limonoids in a variety of citrus juices is a major problem in the citrus industry. Among 38 limonoids isolated from Citrus and its hybrids, limonin, a bitter member of the group, occurs widely in citrus juices and is the major cause of ...

Limonoids from the fruits of Melia toosendan
Phytochemistry, 2012Fifteen limonoids, meliatoosenins E-S (1-15), and 10 known compounds were isolated from the fruits of Melia toosendan. Their structures were elucidated on the basis of extensive spectroscopic methods including DEPT, HSQC, HMBC, (1)H-(1)H COSY, and ROESY experiments.

Simple Enantioselective Approach to Synthetic Limonoids
Journal of the American Chemical Society, 2008An enantioselective and short approach to the synthesis of limonoids has been applied successfully to the simplest limonoid, 2. The carbon atoms of the tetracyclic framework were assembled in a single operation from the acylsilane 3 and the acetylenic sulfone 4 to form the chiral epoxide 5.

Limonoid content of sour orange varieties
Journal of the Science of Food and Agriculture, 2011AbstractBACKGROUND: Modern Citrus cultivars are thought to have arisen from three parents: the pummelo, the mandarin, and citron. Taxological and genetic data support that sweet and sour oranges share a common parentage. However, as their name suggests, the organoleptic properties of the fruit from these two families is distinctly different.

Limonoid derivatives from Astrotrichilia voamatata
Phytochemistry, 2000The stem bark of Astrotrichilia voamatata (Meliaceae) has yielded the novel limonoids voamatins C and D. These compounds represent a new type of pentanortriterpenoid and are unique in containing a ring A cyclic ether.

Degraded limonoids from Melia azedarach
Phytochemistry, 1998Two new degraded limonoids, azedararide and 12alpha-acetoxy fraxinellone, were isolated together with two known degraded limonoids, fraxinellone and fraxinellonone, as ichthyotoxic substances from the root bark of Melia azedarach. Their structures were elucidated by spectroscopic and chemical means.

Cytotoxic Limonoids from Melia azedarach
Planta Medica, 2012Five new compounds (1-5), including two limonoids, one triterpenoid, one steroid, and one sesquiterpenoid, along with nine known limonoids (6-14), were isolated from the bark of Melia azedarach. The structures of the new compounds were elucidated by 2D NMR spectroscopy and mass spectrometry.
