Abstract
- Objective: To control the quality of Gaultheria leucocarpa var. yunnanensis the contents of lignans in these plants from different provinces were detected.<br />Method: HPLC was adopted using Hypersil-18 column (0.4 cm x 25 cm), methanol: acetonitrile: water (30:5:65) as mobile phase.<br />Result: The calibration curves of D1(gaultherinA), D2[(-)-5'-methoxyisolariciresinol-2 alpha-O-beta-D-xylopyranoside)], D4[(+)-lyoniresinol-2 alpha-O-beta-D-glucopyranoside)] were linear in the range of 0.10-0.40 microgram, 0.03-0.13 microgram, 0.02-0.09 microgram, respectively. The average recovery of D1 was 98.9% and RSD was 2.6%.<br />Conclusion: Comparing the samples from Jinxiou(158.2 mg.100 g)-1 and Kumming(154.8 mg.100 g)-1, that of Guiyang showed the highest content of LD(208.8 mg.100 g)-1. The content of LD in the tender above-ground part was 1.3 times higher than that in the wilt.
