ویژگی های زمین شیمیایی، کانی شناسی، و میکرومورفولوژیکی خاک ها و سنگ مادر مربوطه در منطقه بین بخش های جنوبی زاگرس و خلیج فارس تا دریای عمان(استان هرمزگان، ایران) مورد بررسی قرار گرفت. هدف های این مطالعه شناسایی تغییرات در خصوصیات فیزیکی، شیمیایی، و ترکیب کانی شناسی خاک، مطالعه میکرومورفولوژی و تکامل خاک، و بررسی توزیع عنصر خاک بر اساس هوازدگی، پروسه های خاک و زمین شناسی جهت توصیف اثرات مواد مادر...
15 صفحه اولBiotransformation of Hydroquinone to Arbutin by Cell-Suspension Cultures of Three Thai Solanaceous Plants
Cell-suspension cultures of Capsicum annuum L., Solanum aculeatissimum Jacq. and, Datura fastuosa L. (Solanaceae) were established and investigated for the ability to biotransform exogenously-supplied hydroquinone to arbutin. All cultures exhibited good 24-day growth in Murashige and Skoog medium, supplemented with 2,4-dichlorophenoxyacetic acid and benzylaminopurine as plant growth regulators,...
متن کاملQuantitative Determination of Arbutin and Hydroquinone in Different Plant Materials by HPLC
A simple, fast method of high-performance liquid chromatography for the determination and quantification of arbutin and hydroquinone in many different raw materials was developed and validated. The optimum conditions for the separation and detection of these two constituents were achieved on a LiChro-CARD 125-4 Superspher®100 RP-18 column with the water-methanol (gradient elution) mobile phase ...
متن کاملRelative attractiveness of colour traps to pear psylla in relation to seasonal changes in pear phenology
Monitoring of pear psylla (Cacopsylla pyricola (Förster), Hemiptera: Psyllidae) prior to spring bud break could aid in predicting the size of subsequent spring populations and lead to improved proactive management decisions. Yellow traps are commonly used to monitor hemipteran pests including pear psylla, but very little is known regarding seasonal changes in attractiveness of yellow traps or r...
متن کاملProduction of Arbutin by Biotransformation of Hydroquinone Using Peganum harmala, Varthemia persica and Pycnocycla spinosa Cell Suspension Cultures
Cell cultures of Varthemia persica, Peganum harmala and Pycnocycla spinosa have been studied to evaluate their abilities to bioconvert exogenous hydroquinone. Arbutin is an important substance that has several pharmaceutical applications; therefore, we have established V. persica and P. spinosa cultures which seem to be able to metabolize hydroquinone. C...
