Nowadays, chemotherapy is still the main effective treatment for cancer. Herb prescriptions containing(also known as"Guang-Huo-Xiang") have been widely used in Chinese medicine today. In our research, we found that patchouli alcohol, a compound isolated from the oil of, exerted antitumor ability against human lung cancer A549 cells ability bothand. MTT assay was used to assess cell viability. Hoechst 33342 staining and TUNEL cover glass staining provided the visual evidence of apoptosis. Caspase activity measurement showed that patchouli alcohol activated caspase 9 and caspase 3 of mitochondria-mediated apoptosis. Consistently, patchouli alcohol inhibited the xenograft tumor. Further investigation of the underlying molecular mechanism showed that MAPK and EGFR pathway might contribute to the antitumor effect of patchouli alcohol. Our study proved that patchouli alcohol might be able to serve as a novel antitumor compound in the clinical treatment of lung cancer.
