Description
Summary:Kang-chih-ma is the dried roots and stems of Helicteres angustifolia (Sterculiaceae) and a commonly used folk herbal drug in Taiwan. It possesses anti-dotal, analgesic, anti-inflammatory and anti-bacterial effects and is also known as a kind of tumor inhibitory plant. To evaluate the quality of H. angustifolia, a simple, rapid and accurate high-performance liquid chromatographic (HPLC) method was developed for the assay of three lupane type triterpenes: 3β-acetoxy-27-benzoyloxylup-20(29)-en-28-oic acid methyl ester (methyl helicterate), 3β-acetoxy-27-benzoyloxylup-20(29)-en-28-oic acid, and 3β-acetoxy-27-( p-hydroxyl) benzoyloxylup-20(29)-en-28-oic acid methyl ester. The present HPLC system used an Inertsil ODS-2 column by gradient elution with acetonitrile and water as the mobile phase and detected at UV 230 nm. Regression equations revealed good linear relationships (correlation coefficients: 0.9922–0.9997). The relative standard deviations of these three constituents ranged between 1.05–3.14% (intraday) and 2.12–4.38% (interday). The contents of these three constituents of the heartwood and the bark of the roots of H. angustifolia in five different samples have also been determined.
