- Abstract
- Phytochemicals were isolated from leaves of the fiber crop, ramie (Boehmeria nivea, Bn), using open column chromatography and medium pressure liquid chromatography. Their structures were identified as β-sitosterol, (−)-loliolide, rutin, and pyrimidinedione by MS, 1H-, and 13C-NMR spectroscopic analysis. Among them, (−)-loliolide was isolated for the first time from B. nivea. A content analysis of (−)-loliolide in B. nivea collected from different regions and harvest times was conducted by HPLC. The highest content of (−)-loliolide was found in Bn-23 harvested in September. These results will be helpful to use the plant which harvest in September as a high content phytochemical additive in food, health supplements, and medicinal products. © 2016 Korean Society of Pharmacognosy.
