Stuntz.Synonym: Prosopis juliflora DC.Family: Mimosaceae.
Habitat: Argentine, Arid, Mexican, Peruvian and Australian species have been introduced into India.
English: Mesquite.Folk: Khejaraa, Vilaayati Kikar, Kaabuli Kikar.Action: Gum—inferior to Gum arabic. The dry wood contains 0.9, bark 3.0-8.4, and roots 6-7% tannin.
The leaves contain piperidine alkaloids, juliprosinene, juliflorinine and N-methyljuliforidine. Other alkaloids present in the leaves are juliprosine, isojuliprosine, juliflorine, julifloricine and julifloridine.A mixture of alkaloids containing mainly juliprosine and isojuliprosine showed significant antifungal activity against dermatophytes (comparable to griseofulvin).The alkaloid fraction also showed broad spectrum bactericidal action against both Gram-positive and Gramnegative bacteria (comparable to antibiotics like penicillin, streptomycin, ampicillin, sulphamethoxazole and te- tracycline).Significant activity of juliflorine against fungi and bacteria, and that of julifloricine against bacteria has also been reported.The fruit gave a flavone glycoside, patulitrin which exhibited cytotoxic activity.
