| Summary, etc. | This study describes the influence of biosynthesized silver nanoparticles <br/>(Ag-NPs) on phytochemicals and their activities in the cell suspension cultures <br/>(CSC) of Zantedeschia aethiopica. To determine the effect of spirulina aqueous <br/>extract (SAE), plant growth regulators, and SP-AgNPs on the accumulation of <br/>biomass and bioactive compounds in CSC of Zantedeschia aethiopica. The <br/>medium comprising MS salts and sucrose (30 g/L) with 1.5 g/L of SAE and SP-<br/>AgNPs at 30 days of CSC was appropriate for biomass and bioactive compound <br/>accumulation. SP-AgNPs (5 mg/L) elicited CSC extracts that had significantly <br/>enhanced the production of total phenolic content (TPC) (4.27 mg/g-FW), total <br/>flavonoid content (TFC) (3.88 mg/g FW), and DPPH radical scavenging assay <br/>(RSA) (80.03%) compared to the control CSC extracts for TPC, TFC, and DPPH <br/>(0.61, 0.42 mg/g, and 48.80% respectively). The contents of superoxide dismutase <br/>(SOD), peroxidase (POD), and catalase (CAT) were highly elevated in SP-AgNPs <br/>(5 mg/L)-elicited CSC ( 4.5,3.3, and 2.5 U/mg respectively) when compared with <br/>non-elicited CSC. SP-AgNPs elicited CSC showed more phenolic compounds <br/>(1422.28µg/g) than the control CSC (306.31 µg/g). Because of these metabolic <br/>changes, the secondary metabolites produced in the SP-AgNPs -elicited CSC <br/>extracts of Zantedeschia aethiopica. The study suggested the effectiveness of the <br/>elicitation process in enhancing the accumulation of phenolic and flavonoid <br/>compounds and antioxidant activities. SP-AgNPs-elicited CSC offered an <br/>effective and favorable in vitro method to improve the production of bioactive <br/>compounds (secondary metabolites). |

| Summary, etc. | تشرح هذه الدراسة كيف تتأثر المواد الفيتوكيميائية (المركبات النباتية الفعالة) وأنشطتها في مزارع الخلايا المعلّقة لنبات Zantedeschia aethiopica (Calla lily) بجزيئات الفضة النانوية المُخلقة حيويًا باستخدام مستخلص السبيرولينا (SP-AgNPs).اُستخدم وسط MS يحتوي على سكروز (30 جم/لتر)، ومستخلص سبيرولينا (1.5 جم/لتر)، وجزيئات SP-AgNPs، حيث أظهر التركيز 5 ملجم/لتر أفضل النتائج في تعزيز الكتلة الحيوية والمركبات النشطة بيولوجيًا.ارتفع المحتوى الكلي للفينولات (TPC = 4.27 ملجم/جم FW) والفلافونويدات (TFC = 3.88 ملجم/جم FW) والنشاط المضاد للأكسدة (DPPH RSA = 80.03%) مقارنة بالمزارع غير المعاملة.كما زادت أنشطة الإنزيمات المضادة للأكسدة SOD (4.5)، POD (3.3)، وCAT (2.5 وحدة/ملجم).بلغ تركيز المركبات الفينولية في المزارع المعاملة 1422.28 ميكروجرام/جم مقابل 306.31 ميكروجرام/جم في غير المعاملة.تشير النتائج إلى أن التحفيز بجزيئات SP-AgNPs ساهم بوضوح في تعزيز تراكم المركبات الفينولية والفلافونويدية وتحسين النشاط المضاد للأكسدة في مزارع الخلايا المعلّقة لنبات Zantedeschia aethiopica. |
