“…It is an important species because of its high nitrogen fixing potential in very dry areas and in drought seasons and also it provides shelter and food to many species of animals on its nectar, pollen, leaves and fruits (Almaraz-Abarca et al, 2007), P. juliflora are rich source of piperidine alkaloids. Many alkaloids such as juliflorine, julifloricine and julifloridine (Ahmad et al, 1978), juliprosine (Daetwyler et al, 1981), juliprosinene and juliflorinine , 3'-oxojuliprosopine, sceojuliprosopino l, 3-oxojuliprosine and 3'-oxojuliprosine (Nakano et al, 2004) have been isolated from leaves and have proven to be pharmacologically active Aqeel et al, 1989), P. juliflora is used as a traditional medicine on different continents for curing catarrh, colds, diarrhea, dysentery, excrescences, flu, hoarseness, inflammation , measles, sore throat, and for the healing of wounds (Hartwell, 1971). Its juice is used in folk remedies for the cancerous condition.…”

Prosopis juliflora belongs to the family Fabaceae and is commonly known as mesquite. It has been used as a folk remedy for catarrh, cold, diarrhea, dysentery, excrescences, flu, hoarseness, inflammation, measles, sore throat, and in the healing of wounds. Its antibacterial, antioxidant, antifungal, antitumor, and anthelminitic activities are also reported and it contains phytochemicals such as flavonols, alkaloids, tannins, ellagic acid, glycosides, steroids, and various phenolic compounds. It is reported to be used as feed for cattle worldwide. The present study was conducted to investigate the in-vitro antioxidant (DPPH assay) and Preliminary phytochemical screening of ethanol extract of P. juliflora. The ethanolic leaves extract of P. juliflora was screened for antioxidant screening using 2.2Di (4-tert-octylPhenyl)-1-Picryl-Hydrazyl (DPPH), compared with p. galate as standard antioxidant. The tested antioxidant activity gave (61.55 ± 1.02 RSA %) in comparison to the control of propyl galate levels (88 ± 0.07RSA %) and the preliminary phytochemical screening of the leaves revealed that the plant contains Alkaloids, Flavonoids, Saponins, Tannins, Anthraquinone Glycoside and Coumarins.

“…(Fabaceae) is widespread in Saudi Arabia, USA and India (Kirtikar & Basu 1975). The plant is known for its medicinal value and many alkaloids such as juliflorine, julifloricine and julifloridine (Ahmad et al 1978), juliprosine (Daetwyler et al 1981), juliprosinine and juliflorinine (Ahmad et al 1989a(Ahmad et al , 1989b, benzene insoluble alkaloidal fraction (containing two major and three minor alkaloids) (Ahmad et al 1989a(Ahmad et al , 1989b have been isolated and their biological activities in vitro have been demonstrated. The present study reports the antibacterial activity of the alkaloid fraction of P. juliflora against important phytopathogenic Xanthomonas pathovars viz., Xanthomonas axonopodis pv.…”

Aqueous extract, different solvent extracts and isolated constituents of leaves of Prosopis juliflora (Sw.) DC. (Fabaceae) were assayed for antibacterial activity by cup diffusion method against three phytopathogenic Xanthomonas pathovars viz., Xanthomonas axonopodis pv. malvacearum, X. a. pv. phaseoli and X. campestris pv. vesicatoria associated with angular leaf spot of cotton, common blight of bean and bacterial spot of tomato respectively and 14 human pathogenic bacteria. Aqueous, methanol and ethanol extracts showed significant antibacterial activity against all pathovars of Xanthomonas and the activity varied among 14 human pathogenic bacteria. Methanol extract was subsequently fractioned and monitored by bioassay leading to the isolation of active fraction and confirmed as alkaloids by further phytochemical analysis. The active fraction recorded highly significant antibacterial activity in vitro (MIC 6, 5 and 4 mg/ml for Xanthomonas pathovars and 3 and 5 mg/ml against Staph. aureus and Strep. faecalis) compared with synthetic antibiotics such as Bact-805 and K-cycline tested at the recommended dosage for phytopathogenic bacteria and Gentamycin and Streptomycin discs for human pathogenic bacteria.

“…Alternatively, ketene elimination could lead to the ion at m / z 250 (pathway X). A series of ethylene eliminations from the ions at m / z 282 (pathway XI) and 268 (pathway XII) have been proposed . The fragment ion at m / z 43 (pathway XIII) also correlated with an acylium ion from the parent structure.…”
