ChemInform Abstract: ALKALOIDS OF MURRAYA KOENIGII. STRUCTURES OF MAHANIMBINE, KOENIMBINE, (‐)‐MAHANINE, KOENINE, KOENIGINE, KOENIDINE, AND (+)‐ISOMAHANIMBINE

Hypoglycemic effects of Murraya koenigii on normal and alloxan-diabetic rabbits

“…Several Carbazole alkaloids (Joshi et al, 1970;Narasimhan et al, 1975;Narasimhan and Kelkar, 1976;Chakraborty et al, 1978;Wang et al, 2003), Copolin-␣-glucoside and free glucose (Guptha and Nigam, 1971) have been reported to be present in Murraya koenigii. The essential oils of Murraya koenigii possess antibacterial and antifungal activity (Goutam and Purohit, 1974).…”

Effect of mahanimbine, an alkaloid from curry leaves, on high‐fat diet‐induced adiposity, insulin resistance, and inflammatory alterations

“…(Curry leaves) and structure (Fig. a) was confirmed by comparing mass spectrometry and NMR data with reported literature . Details of extraction, isolation and quantification procedures are provided in the supplementary information.…”

Murraya koenigii

“…The pure oil was active against the first three organisms even at a dilution of 1: 500 33 . The acetone extract of the fresh leaves of M. koenigii on fractionation gives three bioactive carbazole alkaloids named as mahanimbine, murrayanol and mahanine, which has shown mosquitocidal, antimicrobial and topisomerase I and II inhibition activities 34 …”

“…The oil is used externally for bruises, eruption, in soap and perfume industry 12 . The phytoconstituents isolated so far from the leaves are alkaloids viz., mahanine 13 , koenine, koenigine, koenidine 14 , girinimbiol, girinimibine 15 , koenimbine, O-methyl murrayamine A, O-methyl mahanine, isomahanine, bismahanine, bispyrayafoline 16 and other phytoconstituents such as coumarin glycoside viz., scopotin, murrayanine 17 , calcium, phosphorus, iron, thiamine, riboflavin, niacin, vitamin C, carotene and oxalic acid. The essential oil from leaves yielded di-alpha phellandrene, Dsabinene, D-_-pinene, dipentene, D-_-terpinol and caryophyllene 18 .…”
