Extractives from West African Members of the Family Meliaceae

Xyloccensins X1 and X2, Two New Mexicanolides from the Fruit of a Chinese Mangrove Xylocarpus granatum

“…Mexicanolide, a tetranortriterpene with a characteristic bicyclo[3.3.1 2,10 ]nonane ring system, was isolated from Khaya grandifoliola and its structure was determined by single-crystal X-ray diffraction analysis [1]. To date, many mexicanolides showing antifeedant and antifungal activities have been reported from meliaceae plants [2 -7].…”

The structure of phragmalin: an X-ray analysis of phragmalin iodoacetate

“…The name 'meliacins' was later proposed to characterize these compounds (Bevan, Ekong & Taylor, 1965).…”

Occurrence, Biosynthesis, Biological activity and NMR Spectroscopy of D and B, D Ring Seco-limonoids of Meliaceae Family

“…The basic limonoid skeleton may be generated by the formation of a furan ring by oxidation of the triterpene side chain [14][15]. Limonoids have been classified on the basis of which of the four rings, designated as A, B, C and D in the intact triterpene nucleus, have been oxidized.…”

“…The family Meliaceae has produced several D-ring seco-limonoids (gedunins and khivorins) and B, D-ring seco-limonoids (for example, angolensates, mexicanolides, phragmalins). Oxidation of the D-ring of apo-euphol triterpene leads to the formation of gedunins [15] ( Figure 1). The opening of gedunin's B-ring leads to the formation of andirobin and subsequently of angolensates [15].…”
