Phytochemical Screening of Alchemilla Vulgaris, Sophora Japonica , Crataegus Azarolus, and Their Inhibitory Activity on Lipase and α-Amylase
Seffo Samah, Kattah Abdullah, Nayal Ream
Abstract: Phytochemical screening of Alchemilla Vulgaris (leaves and flowers) ,Sophora Japonica, and Crataegus Azarolus (leaves and fruits ) , have been determined, and the results showed that the different plant parts of the studied plants contained the following compounds: phenols, carbohydrates, , flavonoids, , saponins, , tannins, and glycosides. While it has shown the absence of alkaloids and cardinols, except the leaves ofCrataegus Azarolus that contained alkolois.The effect of Alchemilla Vulgaris (leaves and flowers),Sophora Japonica, and Crataegus Azarolus (leaves and fruits ) on lipase activity and α –amylase activity were screened by used different extracts[MeOH; MeOH 70% EtOH ; EtOH70% ; Hexane ; Chloroform]. to test their anti-obesity activity using porcine pancreatic lipase inhibitory assay, and porcine pancreaticα –amylase. The results showedthat the extract obtained withpolarsolvents have a goodinhibitory activity, and the highest effect on lipase activity was in the MeOH extractsbut the highest effect onα –amylase activity was in the MeOH 70% extracts,on the contrary the non-polar solvents (Hexane ; Chloroform) have avery weak effect on lipase and α –amylase activity,also we showed that the polar extracts of Alchimalla Vulgaris (leaves and flowers) have the highest effect on lipase activity and α –amylase activity comparative with the extracts of Sophora Japonica , and Crataegus Azarolus (leaves and fruits)These results suggest that the chemical content of polar extracts of these plants might be of therapeutic interest with respect to the treatment of obesity.

Abstract : Introduction: The objective of this study is to establish the validity and reliability of the “SVQCLI” Nursing Course’s Quality Assessment Scale, in order to investigate and measure the quality of the nursing degree course on a sample of Italian students, with a descriptive-correlational research project. Methods: The SVQCLI scale was used, consisting of 65 items within 7 sub-scales. The examined sample includes 63 students answering these questions on a Likert-based scale. Results: For the construct validity of the SVQCLI scale, an analysis of the main components was performed using the criterion according to which only factors with a self-value greater than 1 are extracted. This revealed that the factorial structure consists of 7 dimensions, not 10 as in Vellone’s studies. Concerning reliability of the SVQCLI scale, the internal consistency was tested with the Cronbach alpha, which gave a satisfactory result on all 7 factors as they all far exceeded 0.70. Conclusion: The SVQCLI scale seems to provide an effective way for beginning the quality assessment of both the clinical learning environment and the degree course itself, through the student’s reading key.
Effect of gamma irradiation on thespectroscopic studies of CeO2-doped Zinc Phosphate Glass
Eman Almamo, Hala Wattar, Ismail Alsaleh
Abstract: UV-visible and FTIR spectroscopic properties of some prepared undoped zinc phosphate and CeO2-doped glasses of the same composition were measured before and after successive gamma ray irradiation. The undoped zinc phosphateglassexhibits strong ultraviolet absorption, which is correlated with the presence of trace iron impurities within the raw materials used for the preparation of such glass.The undoped glass shows after gamma irradiation with 10.3 kGy/hr, the broadness of the UV absorption extending from 200 to 339 nm and permanence band centered at 728 nm. FOR 7CeO2-doped glasses produces absorption extending from 200- 354 nm and showing a kink at about 367 nm and existence visible band centered at about 728 nm, but the UV absorption remains unaffected with one peak at about 728 nm. Infrared absorbtion spectra of the prepared glasses reveal characteristic IR vibration due to characteristic phosphate groups according to glass composition and the effects of CeO2 or gamma irradiation are observed to be limited.
In Vitro Evaluation of Anticoagulant and Phytochemical Screening of Some Medicinal Plants in Syria
Malaz Albasha, Abdullah Kattah, Imad Balid
Abstract: In this study, the active components of theaerial parts, and roots of Melilotus Officinalis L, Sonchus Oleraceus L and Anethum graveolens L,plants were extracted by using different solvents of methanol 70%, ethanol 80%, methanol, ethanol, ethyl acetate and hexane.The extracts were used for anticoagulant assays.PT and APTT assays were carried out citrated plasma of healthy volunteer donors with different concentration of the extracts. The methanol 70% and ethanol 80% extracts of Melilotus Officinalis L, Sonchus Oleraceus L and Anethum graveolens L, prolonged the timetaken for blood clotting in all the tested methods. The activity was increasing as the concentration of extracts increased. Qualitative phytochemical screening of carbohydrates, comarins and tannins were observed in all plant extracts, while flavonoids and phenolic acids were found in extracts of methanol 70%, ethanol 80% methanol and ethanol for aerial parts and roots of Melilotus Officinalis L, Sonchus Oleraceus L and Anethum graveolens L.The alkaloids were found only in extracts of methanol 70%, ethanol80% methanol and ethanol for the aerial parts of Sonchus Oleraceus L, and their absence were observed entirely in Melilotus Officinalis Land Anethum graveolens L, Saponins were present only in extracts of methanol 70%, ethanol80%methanol and ethanol for the aerial parts of Melilotus Officinalis L and their absence were observed entirely in Sonchus Oleraceus L and Anethum graveolens L.
