  • Objectives : The present study was performed to clarify the antioxidant and anticancer effects of extract of stamens of Nelumbo nucifera and Kaempferol. Methods : Antioxidant effect was measured by DPPH-radical scavenging activity for electron donating ability (EDA), superoxide dismutase (SOD)-like activity for SOD and lipid peroxidation. Anticancer effect was assessed by MTT absorbance for cytotoxicity. Results : Vitamin E, Kaempferol and ethyl acetate extract of stamens of Nelumbo nucifera increased SOD-like activity and DPPH-radical scavenging activity dose-dependently. On the contrary, lipid peroxidation was time-dependently decreased. Furthermore, Kaempferol and ethyl acetate extract of stamens of Nelumbo nucifera significantly decreased the growth rate of C6 glioma cells. Conclusions : These results suggest that ethyl acetate extract of stamens of Nelumbo nucifera may be a putative antioxidant or anticancer substance.

  • The potential antioxidant and anticancer activities of Hexane, EtOAc (Ethyl acetate), BuOH (n-Buthanol) and water fractions from methanolic (MeOH) extract of Picrasma quassioides (D. Don) Benn. were evaluated in vitro. Tested fractions showed strong antioxidant activity, especially EtOAc fraction had the highest activity ($IC_{50}\;=\;114.01\;{\mu}g/mL$), containing high total phenolics and total flavonoids contents, showed $67.59\;Tan\;{\mu}g/mg$ and $64.95\;Que\;{\mu}g/mg$ respectively. Anticancer activity of these fractions was tested by MTT assay on HT-29 (the human colon carcinoma cells) cell line. BuOH fraction not only showed very high anticancer activity, but also had no cytotoxic effect on 293 (the human normal kidney cells) cell line. Considering these results, we used BuOH fraction of MeOH crude extract from P. quassioides (D.Don) Benn. to do assessment of apoptosis by flow cytometry and the mRNA expression levels of widely established apoptotic-related genes on HT-29 cell line. All the experiments showed that BuOH fraction can induce apoptosis on HT-29 cell line strongly. Taken together, methanolic extract of P. quassioides has potential for antioxidant and anticancer activities products.

  • Artemisia capillaries is a major important food and medicinal resource in Korea. In order to confirm the biological activities of Artemisia capillaries, we investigated antioxidant and anticancer activities from in vitro assays. The Artemisia capillaries methanol (MeOH) extracts was used for the evaluation of DPPH scavenging, total phenolic content, total flavonoid content, hydroxyl radical (${\bullet}OH$) scavenging, reducing power assay as antioxidant activity, as well as anticancer activities as MTT assay. As a result, the Artemisia capillaries MeOH extracts showed potent antioxidative activity and anticancer activity in vitro. These results suggest that the Artemisia capillaries MeOH extracts have a potential alleviated oxidation process, cell motility activity, and tumorigenesis.

  • Eucommiae Cortex (EC), bark of Eucommia ulmoides, has been known as a traditional medicine to regulate hypertension and immune system. Because silk of gum in the EC blocks the release of active ingredients, EC generally has been utilized after processing with carbonization or salt-water to breakdown it. This study aimed to investigate the differences of non-processed EC and processed EC on antioxidant and anticancer properties. Antioxidant capacity was assessed by measuring the content of total polyphenols, reducing power, and ABTS radical scavenging effect. And anticancer effects were examined by evaluating the viability of pancreatic cancer cells and wound healing ability. The results demonstrated that processed EC contained more content of polyphenols and exhibited more potent reducing power and radical scavenging effect than non-processed EC. In addition, processed EC more efficiently inhibited proliferation and migration of pancreatic cancer cells. These results suggest that processing of medicinal plants can improve the biological properties such as antioxidant or anticancer activity, which may lead to the development of herbal medicine treatment technology.

  • Many studies on broccoli have analyzed the functional components and their functionality in terms of antioxidant and anticancer activities; however, these studies have focused on the florets of different varieties. Investigation of the functionality of broccoli by-products such as leaves, stems, and leaf stems from different cultivars and harvest dates might be valuable for utilizing waste materials as useful food components. Total phenolics and sulforaphane contents, and antioxidant and anticancer activities were measured in the leaves, leaf stems, and stems of early-maturing (Kyoyoshi), middle-maturing (Myeongil 96), and late-maturing broccoli (SK3-085) at different harvest dates. Total phenolics in the leaves of Kyoyoshi were about 1.8-fold to 12.1-fold higher than those in all of the other cultivars and parts. The sulforaphane content of Kyoyoshi was 2.8-fold higher in the stems than in the florets. Antioxidant activities using 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity and oxygen radical absorbance capacity were highest in Kyoyoshi, followed by Myeongil 96 and SK3-085, most notably in the leaves harvested at the immature stage. Inhibition activity of cell growth against the NCI-H1299 cell lines was highest in the leaves of all cultivars in decreasing order of florets, leaf stems, and stems. The leaves harvested in October (nonflowering stage) had the highest inhibition activity, while those harvested in January (mature broccoli) showed the lowest. The results of this study demonstrate that broccoli leaves and stems contain high levels of total phenolics, and high antioxidant and anticancer activities and can provide opportunities for early-maturing broccoli as functional fresh raw vegetables.

  • The anticancer and antioxidant effect of different lengths of saturated fatty acids was tested on NIH3T3 fibroblasts and human skin melanoma cellsn in this study. The cell existence rate and antioxidizing capacity and optic reservation of cells were observed. This saturated fatty acid was concentration-dependent. IC50 Concentrations in NIH3T3 fibroblasts, human skin melanoma cells and DPPH radical scavenging activity of fatty acid was increasing the order of carbochain length ; caprylic acid < lauric acid < palmitic acid < stearic acid. The reduction in cell number and morphological change in human skin melanoma cells was increasing the order of carbochain length ; caprylic acid < lauric acid < palmitic acid < stearic acid. These results suggest that carbochain length of fatty acid can be used as structure-activity relationships for anticancer and antioxidant.

  • In this study, we were performed to elucidate the antioxidant and anticancer activity by leaves extracts from Acer tegmentosum (AT-L). In DPPH, ABTS radical scavenging activity, the AT-L revealed the high scavenging activity. Especially, the AT-L measured the highest ABTS radical scavenging activity, which is higher than ascorbic acid. The types of human cancer cells for evaluating the anticancer activity were colorectal cancer (SW480), prostate cancer (PC-3), breast cancer (MCF-7), pancreatic cancer (AsPC-1), lung cancer (A549) and liver cancer (HepG2). Human cancer cell viability was measured using MTT assay. Treatment of the AT-L decreased the cell viability and induced apoptosis in SW480 cells. These results suggest that extracts of the AT-L can be used as supplementary material for developing the natural antioxidant and anticancer drug for human cancer cells.
