Phyto‐Pharmacological Review onMurraya koenigii(L.) Spreng: As an Indigenous Plant of India with High Medicinal Potential

“…Minor chemical constituents such as moisture (63.2 %), fat (6.15 %), total sugars (18.92 %), starch (14.6 %), crude fiber (6.8 %), acid insoluble ash (1.35 %), total nitrogen (1.15 %), phosphorus, thiamine, iron, riboflavin, vitamin C, carotene, oxalic acid, and niacin. [7,10,[19][20] Mahanimbine, isomahanine, koenimbine, mahanine, and girinimbine were isolated from the seeds of M. koenigii (L.) Spreng. Experimental work revealed that the petroleum ether seed extract contained 2-methoxy-3-methylcarbazole.…”
