In this study, the extraction technology of total flavonoids from Podocarpus was studied. the optimum extraction conditions of volatile oil from the leaves and branches of Podocarpus were determined as follows: extraction time 35 mi n, concentration of β -cyclodextrin 40 %, concentration of sodium sulfate 15 %, extraction temperature 30 ℃, under these conditions, the yield of volatile oil from the leaves and branches of Podocarpus was 1. 372 %. A total of 22 compounds were identified by mass spectrometry, accounting for 93.72% of the total chromatographic area. There are 18 terpenes and their oxygen-containing derivatives, accounting for 73.74 % of the total content, including 4 terpineol compounds, 2 terpinealdehyde compounds, 4 aliphatic compounds, accounting for 19.98%, including 2 ester compounds and 2 acid compounds. The main components of the volatile oil were caryophyllene, α-pinene and β-pinene, and the contents were 17.62 %, 9.78 % and 7.47 %, respectively.
