| Abstract | ||
| This Study has been carried out on the leaves and pulp of local Iraqi loquat (Eriobotya Jappanica L.) . This study consisted of tow parts , The first parts concerned with the active naturally occring componds in plants like Flavaniods , Cuamarins extc. The second part concerned with quantitative and qualitative estimation of the essential and active constituents in the leaves and pulps . The primary test showed that the leaves loquat contain the fallowing ingrediants : Glycosides , Tannins , Saponins , Resins , Flavones , Coumarins and the water extract was acidic pH = 5.48 , while the primary test showed that the pulps contain alkoloids , Saponins , Flavones and the water extract was acidic pH = 5.9 . The percentage of essential constituents , it is found that the oil percentage = 1.26% , protein = 18.26% , Moisture = 9.44% , Tannins = 8.9% , crud fiber = 5.3% . The total ash = 12.88 , ash soluble in water = 29.77 mg/gm and ash insoluble in acid = 18.26 mg/gm , while the essential constituents for pulp it is fond that the oil percentage = 2.51% , protein = 25.39% , Moisture = 9.44% , Tannins = 7.8% , crud fiber = 3.1% , total ash = 10.52 , ash soluble in water = 22.24 mg/gm and ash insoluble in acid = 10.98 mg / gm . the experiment , for measuring the degree of swelling for the local loquat leaves and pulps under the room temperature , in dark and during equal periods of time for the leaves and pulps . The leaves require 1 – 2 hours for reading the degree of swelling and then to equation , whereas the pulps on the other hand , take about 48 hours for the same purposes above . | ||
