Abstract: The isopentenyl unit numbers of polyprenols from Greek Pinus pinaster leaves was 14 to 20 by contrasting the retention time of polyprenol reference substance using HPLC. And the polyprenols structure was confirmed as ω-trans2-cisn-OH by 1H and 13C spectrum. The HPLC conditions of a Kromasil C18 ODS-1(150 mm × 4.6 mm, 5 μm) column, methanol-isopropanol (9:16, v/v) as the mobile phase at a flow rate of 0.50 mL/min, column temperature of 25 ℃, PDA detector with detective wavelength of 210 nm were used. The polyprenols from Greek P. pinaster leaves in the range of 1.10-12.10 μg had good linearity (r=0.996 3), the average recovery was 98.21 %, and RSD was 2.27 % (n=6). The result showed that the polyprenols content of dried leaves was 0.33 % . The method was accurate, reproducible and quick to determine the isopentenyl unit number and content of polyprenols from Greek P. pinaster leaves.
