الملخص

هدفت الدراسة الحالية إلى تقييم الخصائص الكيميائية، والكيميائية الحيوية، والنباتية لمستخلصات أوراق نبات الصبار المتوطن (Aloe vacillans Forsskål)، مع التركيز على المجموعات النباتية التي تنمو في محافظة عمران بالجمهورية اليمنية، وتحديد أهميتها التصنيفية. ومن خلال تحليل 59 صفة (26 نوعية و33 كمية)، أكدت التحليلات العددية والإحصائية وجود شكلين مورفولوجيين متميزين: أحدهما ذو أزهار حمراء والآخر ذو أزهار صفراء. وقد أظهر المسح الكيميائي النباتي وجود مركبات حيوية فعالة مثل القلويدات، والفلافونيدات، والفينولات، والعفص، والصابونين، كما حدد تحليل الأشعة تحت الحمراء (FT-IR) المجموعات الوظيفية الرئيسية في كلا الشكلين، بما في ذلك مجموعات الهيدروكسيل، والكربونيل، والروابط الكربونية. وفيما يخص النشاط الحيوي، كشف تقييم القدرة المضادة للأكسدة بطريقة (FBRC) عن كفاءة عالية بلغت 244 ± 5.2 µg ASA/mg للشكل الأحمر و232 ± 4.8 µg ASA/mg للشكل الأصفر، مع وجود فروق ذات دلالة إحصائية (P < 0.05). كما أظهرت نتائج اختبار الفعالية المضادة للميكروبات ضد أربع ممرضات بشرية تفوقاً مستمراً للشكل الأحمر في التثبيط مقارنة بالشكل الأصفر عند جميع التركيزات. تخلص الدراسة إلى أن هذه النتائج تقدم دليلاً قوياً على التمايز التصنيفي بين الشكلين، وتؤكد إمكانيتهما كونهما مصادر طبيعية واعدة للتطبيقات الصيدلانية.
