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.

Background: Cervical cancer is widely acknowledged as the main cause of mortality and a major obstacle to increasing life expectancy, after breast cancer, in women. Natural products have been proven to be a promising source for the development of potential anticancer drugs. Emodin (1,3,8-trihydroxy-6-methyl-9,10-anthracenedione) is shown to exert wide range of biological effects, including antibacterial, hepatoprotective, anti-inflammatory and anticancer. Aim: The major aim of this study was to evaluate the efficacy of emodin against the progression of human cervical cancer. Materials and Methods: The cytotoxic effect of emodin on cervical cancer HeLa cells was assessed by cell viability assay and phase contrast microscopy. Moreover, DAPI staining was performed to analyze nuclear condensation. H2DCFDA staining was done to evaluate ROS generation. Activation of caspases was determined to ascertain mitochondria-mediated apoptosis in cervical cancer cells. Results: The results revealed that emodin strongly inhibited the HeLa cell growth and proliferation; which was validated by cell viability assay and phase contrast microscopy. Moreover, DAPI staining authenticated nuclear condensation and fragmentation in HeLa cells indicating initiation of apoptosis. We also observed significant ROS generation and caspases activation in emodin-treated cervical cancer cells. Conclusion: Our results suggested strong cytotoxic potential of emodin against cervical cancer cells.

Background: This study determined the cytotoxic effects of root and stem bark extracts, fractions, and isolated compounds derived from Pseudocedrela kotschyi on HeLa, MCF-7, and RD cells. Materials and Methods: The cytotoxic activity was determined using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide colorimetric assay against three cell lines (RD, HeLa, and MCF 7) at concentrations ranging from 0.01 to 1000 μg/mL. Isolation of crude saponin was done from the most active ethyl acetate fraction and further purified using vacuum liquid chromatography and preparative thin layer chromatographic techniques. Results: The cytotoxicity assay revealed that the methanol extract from the root bark and the ethyl acetate fraction from the stem bark exhibited marked anticancer activity with IC50 of 87.36 μg/ml and 21.53 μg/ml, respectively, on HeLa cancer cell line and 101.51 μg/mL and 38.46 μg/mL, respectively, on RD cell line. These values are comparable with that obtained from vinblastine and methotrexate used as standard drugs (IC50 values of 0.01 μg/mL and 0.05 μg/mL, respectively). The isolated crude saponins also gave IC50 values of 5.28 μg/mL and 81.52 μg/mL against the RD cell lines and IC50 values of 1.05 μg/mL and 86.8 μg/mL for the MCF 7 cancer cell lines. PTLC led to the isolation of a compound from the crude saponin which was identified as 7-deacetoxy-7-oxogedunin through spectroscopic analysis and comparison with literature data. Conclusions: P. kotschyi could be considered as a potential source of chemotherapeutic agent. However, further research to determine the exact mechanism of action needs to be carried out.

Isodon (Lamiaceae) is a known source of bioactive terpenoids. Diterpenoids isolated from Isodon wightii (Bentham) H. Hara showed antibacterial, antiacetylcholinesterase, antioxidant, anticancer, and anticarcinogenic activities, etc., Hepatoprotective activity of ABA against lipopolysaccharide (LPS) induced liver injury in BALB/c mice was studied. Cytotoxic activity of ABA was tested against cervical cancer cells (HeLa) using MTT assay followed by propidium iodide (PI) staining to identify apoptosis. Histopathological analysis revealed that 1.5 μg/mL LPS induced liver damage was attenuated by ABA in a dose dependent manner. ABA showed cytotoxicity with IC50 value of 176.28 {\textpm} 0.02 μg/mL and PI staining of treated cells showed apoptosis. This study proves that ABA would be a promising natural compound for herbal drug preparation.
