دراسة مقارنة لمحتوى الفينولات والفلافونوئيدات الكلي في أجزاء مختلفة من نباتي شوك مريم Silybum Marianum و زند العبد Syriaca Notobasis المنتشرين في سوريا

الملخص EN

The aim of this research is to compare between Silybum Marianum and Notobasis Syriaca in their content of active substances (phenols and flavonoids).

Different polarity Extracts of fruits, flowers, and aerial parts (part of the stem with thorns) were prepared for both plants.

The total phenolic content in each of the previous extracts was determined using Folin-Ciocalteu reagent, and the total flavonoid content was determined using Aluminum chloride reagent.

The fruit extract from Silybum Marianum exhibited the highest total phenolic content (120.75±0.8 mgEGA/gD.E), followed by the fruit extract from Notobasis Syriaca (114.99±0.8 mgEGA/gD.E).

As for the highest Total flavonoid content, we obtained from Notobasis Syriaca fruits (11.59±0.057 mgEQ/g D.E), while the total flavonoids content in the rest of the extracts ranged from 3.93±0.08 to 5.85±0.12 mg EQ/g D.E .
