Aim: World widely the human society suffers from various types of cancer due to many causes. Thus, finding out a good anticancer agent is a need of the hour. Medicinal herbs are always considered at pole position whenever we discuss anticancer properties. Numerous herbal plants have been assessed and are subjected to phytochemical analysis to learn more about their anticancer effects. Materials and Methods: To assess the anti-cancerous activity of PZBE extract in MTT assay, cell cycle analysis, and apoptosis studies have been performed using different cancer cell lines. Results: This study aims to assess the impact of ethanolic extract of Pancratium zeylanicum Bulbs (PZBE) against cancerous cells in vitro conditions. MTT assay was used to compare the PZBE extract with Annexin V as a positive control compound against four human cancer cell lines, including Human cervical cancer (HeLa), colon cancer (HT-29), lung cancer (A549) and breast cancer (MCF-7) cell lines with the IC50 values of 209.28 μg/mL for HeLa, 133.09 μg/mL for A-549, 264.46 μg/mL for MCF-7 and 264.75 μg/mL for HT-29 cell lines. Increasing of the populations observed in G2-M and G0-G1 cells by 42\% and 44.78\%, respectively when compared to the control. The graph demonstrates that PZBE extracts significantly induced G0-G1 arrest in A-549 cells. Furthermore, the PZBE extract effectively induced apoptosis when compared to untreated cells, A-549 cells treated with IC50 concentration, and annexin-V double-staining assay demonstrated an increase in the percentage of early and late apoptotic cells. Conclusion: The ethanol extract of Pancratium zeylanicum bulbs demonstrated potent cytotoxic activity against the cancer cell lines HeLa, A-549, MCF-7, and HT-29. The current study{\textquoteright}s findings may be helpful in the development of plant-based anticancer drugs.

Aim: There are many uses for silver nanoparticles in the field of biomedicine due to their exceptional properties. A major application of silver nanoparticles is the increase of antibiotics that are clinically helpful against microbes and drug-resistant bacteria. However, environmentally friendly methods for their synthesis must be developed. Objectives: Current study, the major objective of this research is concentrated on to suggest an easy and well-organized biosynthesis of silver nanoparticles by confirmed antioxidant, anti-inflammatory and anti-diabetic activities. The ATSNPs (Afrohybanthus travancoricus silver nanoparticles) was biosynthesized with A. travancoricus plant like capping and reducing agent. Materials and Methods: The ATSNPs aqueous extract were mixed by water extract of 1mM AgNO3 solution led to appearance of greenish brown to dark brown colour indicates the synthesis of SNPs. The silver nanoparticles were characterized by UV-visible spectroscopy, FT-IR, SEM, XRD, and EDX analysis. Antioxidant assay was tested through DPPH and ABTS+ assays, anti-inflammatory assay through albumin denaturation and antidiabetic assay by α-amylase and α-glucosidase activities. Results: A colour change of solution from dark brown to light brown, absorption peak of ATSNPs as 290 to 300 nm in UV-vis spectroscopy. ATSNPs showed 6 intense peaks in FTIR analysis and functional groups like phenols, alcohols, 1{\textdegree} amines, alkynes, aliphatic amines, aromatics, and alkyl halides were identified. In XRD analysis showed 5 intense peaks at 20.8{\textdegree}, 30.3{\textdegree}, 40.1{\textdegree}, 40.9{\textdegree}, 60{\textdegree}. The EDX analysis the presence of Ag at 3 kev and SEM analysis showed the size of ATSNPs ranges between 88 μm {\textendash} 242 μm. Antioxidant activity was observed the dose dependent manner in both assays. Anti-inflammatory activity of ATSNPs proved maximum inhibition through egg albumin denaturation. Antidiabetic activity exhibits maximum inhibition percentage of α-amylase and α- glucosidase at 10 μg/mL. The lowest IC50 value was noted in α amylase (170 μg/mL) and α glucosidase (134 μg/mL). Conclusion: The obtained results recommended that using ATSNPs, it is likely to represented silver nanoparticles with controlled characteristics and important pharmacological activities.
