| Abstract | Background Researchers have searched for plant-derived medicines over the last few decades. Although much of the focus has been on medicinal herbs, many vegetables, such as sweetpotato, have also been discovered to have medicinal properties due to their high levels of nutrients and phytochemicals. This study aimed to determine the effects of methanolic extracts from sweetpotato leaves and leaves/stems on human lung (A549) and breast (BT549) cancer cell lines. The authors obtained the leafy greens from Tennessee State University’s Organic research farm, extracted with methanol and studied for their cytotoxicity. Methods Alamar blue Assay was used to determine whether the methanolic extracts from fresh sweetpotato leaves (cv. All Purple) and leaves/stems (cv. Carolina Ruby) had the potential to affect cell proliferation in the human lung (A549) and breast (BT549) cell lines in-vitro. Tamoxifen was used as the positive control, while DMSO was used as the negative control. Results Sweetpotato leaves of the All-Purple cultivar and the stem/leaves of the Carolina Ruby cultivar inhibited lung and breast cancer cell growth in a dose-dependent manner. The All purple sweetpotato produced EC50 values of 0.013 µg/µl (R2 = 0.67, P < 0.05) and 0.002 µg/µl (R2 = 0.89, P < 0.05) in the A549 and BT549 cell lines respectively, using the Alamar blue assay. The BT549 cell line treated with all purple leaf extract was less significant than that of the A549 cell line. However, the sweetpotato stem and leaf extract of Carolina ruby had a more significant cytotoxic effect on the A549 cell line with an EC50 value of 0.0014 µg/µl (R2 = 0.99, P < 0.05). Conclusions Anticancer activities of these extracts showed their ability to inhibit the growth of cancer cell lines, such as BT549 (breast cancer) and A549 (lung cancer), in a concentration-dependent manner. Further studies would help determine the bioactive compounds present in these compounds that produce this effect, but more studies would also help determine whether the extracts could induce apoptosis in BT549 and A549 cancer cells, the mechanism of action, and cell cycle progression. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
