Comparative studies of the phytochemistry, proximate analysis, mineral and vitamin compositions of the methanol leaf extracts of Cucumis sativus L. and Daucus carota L.
AbstractCucumis sativus and Daucus carota are medicinal plants used in folkloric medicine to treat and prevent various diseases but the basis for this has not been highlighted. Quantitative phytochemicial analysis revealed the presence of anthocyanins, flavonoids, carotenoids and pyrrolidine in D. carota leaf methanol extract but in C. sativus only flavonoids and carotenoids was found present although in a lower amounts. Proximate analysis revealed that both plants methanol leaf extracts contain moisture, protein, carbohydrate, fat, fiber and ash. The moisture content of C. sativus (95 0.02%) was more than that of D. Carota (82.20 0.01%) but the protein, carbohydrate, fat, ash and fiber contents of D. Carota was more than that of C. sativus. The mineral compositions also revealed the presence of Ca, P, Mg, Fe,Zn,Na, and K in both C.sativus and D. carota although in various proportions. The P, Ca, Mg, Fe and Na contents in D. carota were more than that of C. Sativus, but C. sativus has a higher Zn and K contents than D. carota. The vitamin analysis also revealed the presence of important vitamins including A, B1, B2, B6 , C,E, niacin and folate. The vitamin A content ofD. carota were very high (2,901 0.02g) compared to that of C. Sativus (23 0.01g). These important macroelements, minerals and vitamins embedded in these important plants may be the reasons behind its use in forklore medicine for its various dietary and therapeutic applications.
