Black Mulberry (Morus nigra L.): A Review of Attributes as an Anticancer Agent to Encourage Pharmaceutical Development

Abstract

Recent considerations of natural sources as potential anticancer agents have arisen due to the origins of numerous drugs commonly used in chemotherapy. Plant-based drugs, in particular, have attracted attention for offering the advantage of low adverse effects. Among these, the black mulberry plant (Morus nigra L.) stands out as a natural source of polyphenols, widely used to treat metabolic dysfunctions and confer benefits on human health. This study explores the potential of this plant as an anticancer agent, examining its effectiveness based on the type of application of the plant extracts or isolated substances, extraction methods, and its potential biological effects on cancer cells. Consequently, this study contributes to a better understanding of the distribution of phytochemicals in M. nigra and their applications in the context of cancer field. Among the compounds found in black mulberry are flavonoids, chlorogenic acid, cryptochlorogenic acid, and protocatechuic acid, along with cyanidin-3-O-glucoside as the main anthocyanin on the fruit. The phytochemicals derived from M. nigra exhibit antinociceptive and antimicrobial activities, while also showing protective effects, such as antioxidant properties that underline their potential as anticancer agents. The black mulberry’s roots, stem bark, pulp, and leaves are particularly rich sources of anti-inflammatory compounds. Ethanol and methanol extraction methods appear to be the most effective in cancer management, offering compounds that facilitate the integration of apoptosis induction, cell growth inhibition, and cytotoxicity modulation. These results collectively represent the salient biological attributes that positioned black mulberry as a promising anticancer agent. Therefore, these findings highlight the multifaceted potential of M. nigra as an anticancer agent, making a compelling case for further research to advance prospects in the medical field.
