In this study, the effects of the home remedy herb Tulbaghia violacea on antioxidants, total polyphenol activity, and cancer were investigated. Using methanol/dichloromethane and aqueous solvents, the extracts were produced. The antioxidant activity of the extracts was assessed by the 2,2-diphenyl-1- picrylhydrazyl assay, and their phenol content by the gallic acid method. The extracts were found to be inactive or weak against the HeLa (cervix), human cancer cell lines TK-10 (renal), and PC3 (prostate). It is suggested that these three human cell lines be tested against extracts of water and methanol/ dichloromethane at higher concentrations. The plant{\textquoteright}s leaf extract would also be the best substance to test against the human cell lines TK-10, PC-3, and HeLa. The IC50 values for two to three cell lines show that T. violacea plant extracts (\>100 g/ml) have no effect on cells. T. violacea extract has greater antioxidant activity than the control. A thorough phenolic analysis showed that water leaf extract had the highest quantity of phenolics whereas bulb methanol/dichloromethane extract had the lowest. Both the methanol/dichloromethane and the aqueous extracts have the same characteristics for antioxidant activity. In order to enhance food{\textquoteright}s nutritional content and quality while also supporting excellent health, it has been found that phenolic compounds alter the color, flavor, and other sensory characteristics of the meal. Additionally, they help plants defend themselves against harm from ROS, molecular damage, microbial invasion, insects, and herbivores.

Introduction: Andrographolide is a well-known anticancer phytochemical often isolated from Andrographis paniculata (Burm. f.) Nees. (Acanthaceae). Though Andrographis lineata Wall. ex Nees var. lawii C.B. Clarke (ALw) which also belongs to the same family has an adequate amount of andrographolide; remained untouched for isolation of andrographolide and anticancer studies. Therefore, this study was targeted to isolate the andrographolide from the leaves of ALw and to assess its role inthe induction of apoptosis against the human ovarian teratocarcinoma (PA-1) cell line. Methods: Column chromatography, thin-layer chromatography (TLC), preparative TLC were used for the isolation and purification while melting point, ultraviolet (UV)-visible spectroscopy, Fourier transform infrared (FTIR), proton nuclear magnetic resonance (1H NMR), carbon-13 (C13) nuclear magnetic resonance (13C NMR) analysis were carried out for characterization of the compound. 3-(4,5-dimethylthiaxo-2yl) 2, 5-diphenyl tetrazolium bromide (MTT) assay was carried out for cytotoxicity test and further Annexin-V staining, caspase 3 activity, B-cell lymphoma-2 (Bcl-2) activity, cell cycle analysis, and DNA damage study by terminal deoxynucleotidyl transferase (dUTP) nick end labeling (TUNEL) assays were carried out for apoptosis study. Results: Andrographolide was isolated from the methanolic extract of leaves of ALw which had a melting point of 230 {\textordmasculine}C, λmax at 223 nm. FTIR results proved the presence of hydroxyl group, alkanes, carbon-carbon double bond, and a characteristic gamma lactone carbonyl. NMR data confirmed the 20 carbon structure. In the MTT assay cytotoxicity against PA-1 was at 3.7 μg/ml with other apoptotic assays supporting the induction of apoptosis by the compound at that concentration. Conclusion: ALw is proved to be an alternate source of andrographolide with potential abilities to induce apoptosis in ovarian cancer cells.

Introduction: Exposure to high levels of antioxidants has been linked to the treatment and prevention of some cancers. Although Cakile maritima has a high antioxidant capacity, it is yet to be tested for the ability to inhibit the proliferation of cancer cells. Methods: Solvent extracts prepared from C. maritima plant material were analysed for antioxidant capacity by the DPPH free radical scavenging assay. Anti-proliferative activities against Caco2 and HeLa cancer cells were determined by an MTS based cell proliferation assay. Toxicity was determined by the Artemia franciscana bioassay. The most potent anti-proliferative extract (hexane) was further investigated using non-targeted GC-MS headspace analysis. Results: Good DPPH radical scavenging activity was calculated for all C. maritima extracts. The methanolic and ethyl acetate extracts had particularly strong antioxidant activity (IC50 of 4.7 and 3.4 μg/mL respectively). Interestingly, the hexane extract which had the lowest DPPH radical scavenging activity (IC50 13.6 μg/mL), was the most potent inhibitor or Caco2 and HeLa carcinoma cell growth, with IC50{\textquoteright}s of 12 and 126 μg/mL respectively. The ethyl acetate extract was also a potent inhibitor of proliferation (IC50 values of 185 and 468 μg/mL against Caco2 and HeLa, respectively). The methanolic extract (IC50 values of 2261 and 2046 μg/mL against CaCo2 and HeLa respectively) displayed only moderate anti-proliferative activity, demonstrating that antioxidant activity did not correspond with anti-proliferative activity. All of the extracts were determined to be nontoxic in the Artemia franciscana bioassay, with LC50 values substantially \>1000 μg/mL. Non-biased GC-MS headspace analysis of the C. maritima hexane extract highlighted several interesting compounds that may contribute to the therapeutic bioactivities of the extract. Conclusion: The lack of toxicity and the anti-proliferative activity of the hexane and ethyl acetate C. maritima extracts against HeLa and Caco2 cancer cell lines indicates their potential in the treatment and prevention of some cancers.

Introduction: Terminalia spp. are characterised by their high levels of antioxidant phytochemicals and several species have anticancer activity. This study examines the anti-proliferative activity of T. sericea leaf extracts against Caco2 and HeLa carcinoma cell proliferation. Methods: Solvent extracts were prepared from T. sericea leaves and their antioxidant capacities were determined by the DPPH free radical scavenging assay. Anti-proliferative activities against Caco2 and HeLa cancer cells were determined by an MTS based cell proliferation assay. Toxicity was determined using the Artemia franciscana nauplii bioassay. Results: The methanolic and aqueous T. sericea leaf extracts displayed high antioxidant capacities (equivalent to 150 and 340 mg of ascorbic acid per gram of plant material extracted respectively). In contrast, the ethyl acetate, chloroform and hexane extracts had relatively low antioxidant contents (\≤5 mg of ascorbic acid equivalents per gram of plant material extracted). The antioxidant contents of the T. sericea leaf extracts correlated with the ability of the extracts to inhibit proliferation of Caco2 and HeLa cancer cell lines. The high antioxidant methanolic and aqueous extracts were potent inhibitors of cell proliferation, with IC50 values 120-1400 \μg/mL. The aqueous T. sericea leaf extract was particularly effective, with IC50 values of 528 and 120 \μg/mL against Caco2 and HeLa cells respectively. The methanolic extract also displayed good, albeit substantially less potent, antiproliferative activity against HeLa cells, with an IC50 of 1358 \μg/mL. In contrast, the lower antioxidant content extracts generally did not inhibit cancer cell proliferation. Cell imaging studies detected morphological features consistent with apoptosis in Caco2 cells exposed to sub-lethal concentrations of the methanolic and aqueous T. sericea leaf extracts, indicating that these extracts are functioning by cytotoxic mechanisms. The aqueous T. sericea leaf extract displayed low to moderate toxicity in the Artemia franciscana bioassay, with an LC50 value of 737 \μg/mL. All other extracts were nontoxic. Conclusion: The antiproliferative activity and low toxicity of the T. sericea methanolic and aqueous leaf extracts extracts against HeLa and Caco2 cancer cell lines indicates their potential in the treatment and prevention of some cancers.

Background: Terminalia spp. are characterised by their high antioxidant capacities and many have anticancer activity. This study examines the anti-proliferative activity of T. carpentariae leaf and T. grandiflora leaf, fruit and nut extracts against Caco-2 and HeLa carcinoma proliferation. Materials and Methods: Powdered T. carpentariae leaf and T. grandiflora leaf, fruit and nut were extracted and tested for anti-proliferative activity against Caco-2 and HeLa cancer cell lines using colorimetric cell proliferation assays. Toxicity was evaluated using an Artemia franciscana nauplii bioassay. The extract with the most potent anti-proliferative activity was examined using GCMS analysis and triterpenoid compounds were identified by comparison with a compound database. Results: T. carpentariae leaf and T. grandiflora leaf, fruit and nut extracts displayed potent anti-proliferative activity against Caco-2 and HeLa carcinoma cells. The methanolic T. grandiflora leaf extract was particularly effective at blocking the proliferation of the colorectal carcinoma Caco-2 (IC50 = 372 \μg/mL). The methanol T. carpentariae and T. grandiflora leaf extracts were similarly potent inhibitors of HeLa cervical cancer cell proliferation with IC50 values of 864 and 833 \μg/mL respectively. The methanolic T. grandiflora fruit and nut extracts, as well as all aqueous and ethyl acetate extracts, were moderate to good inhibitors of carcinoma proliferation. In contrast, chloroform and hexane extracts were generally devoid of anti-proliferative activity. The methanolic T. grandiflora extracts displayed low toxicity in the Artemia nauplii bioassay. All other extracts were non-toxic. GC-MS analysis of the methanolic T. grandiflora leaf extract identified 3 lanostane and 2 pentacyclic triterpenoids. Conclusion: The low toxicity and anti-proliferative activity observed with the T. carpentariae and T. grandiflora extracts against Caco-2 and HeLa indicate their potential for the prevention and treatment of some cancers.
