Grade of chemicals here I mean ACS, AR, HPLC and GC-HS. I am working on some natural herbs in order to get their active phytochemicals of interest preferably antimicrobial . Which grade of chemicals will be suitable for efficient extraction of phytochemicals ?
Dear Pragya,
Solvent grade does not shown any noticeable impact on phytochemical extraction efficiency. However, you can go with HPLC grade organic solvent for medicinal plant extraction.
Best Regards,
I would use the highest quality available. The problem is not how well they extract your samples, the problem is trace impurities in the solvents which can concentrate along with your samples and interfere with later analysis.
Since you intend to analyze using HPLC instrumentation, it is better to use HPLC grade chemicals to avoid any impurity. If you want to analyze only the total phytochemicals content, its ok to use AR grade chemicals.
عزيزي اذا تريدتحلبل المواد الكيميائيه من فئة AR الافضل لك استهزام مواز عديمة الشوائب باستخدام HPLCستظهر مواد كبميائيه نباتيةوتتَ باستخزاَ مذيب جيد
