What are the pharmacological activities of Murraya exotica?
This plant has analgesic, anti-inflammatory, anti-neuroinflammation, anticancer, and antitumor pharmacological activities. Its bioactive compounds work to reduce pain perception and mitigate systemic inflammatory responses in various biological models. The plant also exhibits significant neuroprotective potential by suppressing neuroinflammation within the central nervous system. Furthermore, its chemical constituents demonstrate the ability to inhibit the growth and proliferation of malignant cells. These combined properties highlight its therapeutic potential for treating complex diseases ranging from chronic pain to cancer.
According to a study published by "Natural product communications", Murraya exotica L. is one of two aromatic species of Rutaceae used to derive Murrayae Folium et Cacumen (MFC). This traditional Chinese medicine has long been utilized in South China for the treatment of various disorders, specifically for pains and inflammatory lesions. In the essential oil of M. exotica, sesquiterpenes were found to be the predominant constituents, accounting for 87.9% of the oil. The presence of E-caryophyllene, spathulenol, and delta-elemene provides chemical evidence for its medicinal application as MFC. E-caryophyllene is theoretically deduced as a pharmacologically effective component of MFC responsible for local anaesthesia and treating inflammatory lesions.
