Rosemary herb, etc.). Prolongation of the extraction time of essential oil bearing or not containing plant material gives principally similar score reduction (Tables 2 and 3). Also sweetening of essential oil containing herbal teas did not improve their palatability remarkably more than in other herbal teas (Table 4). Analyzing effect of extraction time on palatability of herbal teas rich of tannins (such as Oak bark, Tormentil rhizome, Bistort rhizome, etc.) we did not saw so clear negative trend than, for example, in herbal teas made from St. John’s wort herb or German chamomile flowers, and several other drugs containing different constituents groups. So, the negative effect of tannins to palatability of herbal infusions seems to be overestimated. In conclusion, the present study demonstrates that the distaste of the herbal teas is univocal. Contrary, the favorable palatability of herbal teas strongly depends on the taste perception of the particular subject while the time of extraction or addition of saccharose as a sweetener have only a minor effect on the palatability score.

Accepted 9 May, 2011 Following an initial clean-up step on a silica gel column, preparative high-speed counter-current chromatography (HSCCC) method was successfully established by using n-hexane–ethyl acetate– methanol–water (2.3:2:2:1.3, v/v) as the two phases solvent system to isolate and purify terpenoids from the stem and root bark of Celastrus aculeatus Merr. The isolation was done in less than 260 min and 2.5 mg of nimbidiol (I) and 3 mg of pristimerin (I I) were yielded from 250 mg of the crude extract with the purity of 95.0 and 97.1%, respectively, as determined by high-performance liquid chromatography (HPLC). Their structures were identified by using spectroscopic methods including ultraviolet (UV), electron ionization mass spectrometry (EI-MS), hydrogen nuclear magnetic resonance 1 (HNMR) and 13 CNMR. Nimbidiol and pristimerin were isolated from C. aculeatus Merr for the first time. Key words: High-speed counter-current chromatography, terpeniods, nimbidiol, pristimerin, Celastrus aculeatus Merr. INTRODUCTION Celastrus aculeatus Merr.(Celastrus) (Guo et al., 2004; Kim et al., 1998; Jin et al., 2002; Westerheide et al., 2004) is a Chinese medicine that belongs to the family Celastraceae and the genus Celastrus. For centuries, roots, stems and leaves of C. aculeatus have been used to treat rheumatoid arthritis, osteoarthritis, lower back pain and so on. However, up to now, few phytochemical studies on this plant have been described in the literature. In order to find out the bioactive components, we have studied the chemical components of C. aculeatus Merr. Some of the bioactive components are difficult to separate because of their low contents. Although preparative HPLC or silica gel column makes the isolation and purification much easier than before, the considerable loss of herbal material requires more efficient methods to provide bioactive components. *Corresponding author.

A supportfree liquid-liquid partition chromatographic technique eliminates such adsorption problems (Ito, 1981) has been widely used in preparative separation of natural products (Yang et al., 2009). In the present study, the HSCCC method was developed for the separation and purification of nimbidiol and pristimerin from C. aculeatus Merr. Their structures were elucidated with EI-MS, 1 HNMR and 13 CNMR. As far as we know, the two compounds were obtained from C. aculeatus Merr for the first time.
