The terpenoids in Pogostemon cablin have complex structures and abundant pharmacological effects. Patchouli alcohol(PA) and pogostone(PO) have a high medicinal value by virtue of anti-tumor, anti-inflammatory, antibacterial, antioxidant, and other biological activities. Due to the low content of terpenoid metabolites in P. cablin, the study of biosynthesis and metabolism regulation can provide a biosynthetic basis for obtaining high-content terpenoids. In this study, key enzyme genes in biosynthesis, transcription factors in metabolism regulation, spatio-temporal expression of terpene synthase were reviewed, aiming to provide a reference for the development, protection, and utilization of P. cablin resources.
Keywords: Pogostemon cablin; biosynthesis; metabolism regulation; patchouli alcohol(PA); pogostone(PO).
