  • The present study has been undertake to obtain the fundatmental data of optimum germination condition and to establish storage time for artificial pollinationin Codonopsis lancelata pollen. In vitro condition for germination of freshly collected and stored pollen were examined. The optium temperature for germination of fresh pollen was $25^{\circ}C$. The optium sucrose concentration in the medium ranged from 30 to 40 % and optium pH 6.0% for pollen germination. The rate of pollen germination accelerated considerably in the medium with 1% agar. 30% sucrose, and pH 6. C. lanceolata pollen remained viable for 15 days when stored at 5$^{\circ}C$ with silica gel as desiccant.

  • In order to improve cultivation technuque of C. lanceolata, natural ABA was treated with foliar application periodically during differenctitation of node. The higher is concentration and the earier its foliar application was, the shoter plant height was. Especially, when $10mg;.L{-1}$ of ABA was treated at differentiated stage of 3rd node, plant height was inhibited to 60% of control. But leaf length, leaf width, and number of branches have no significant differnence in comparison wiht control. The fresh weight of subterranean part was similar to control independent of treat-time in the case of $10mg;.L{-1}$. When 1,5 and $10mg;.L{-1}$ of ABA were treated at initial differentiated node stage, plant height inhibited to 20~30% of control, but subterranean part was similar to control. All treatement showed slight antitumor activity by the P388 cytotoxic screening test.

  • The present study was designed to investigate the antihyperlipidemic effect of Coconopsis lanceolata extract in C57BL/6J mice. The mice were divided into four groups: normal diet group (ND), high fat diet group (HFD), positive control group with 0.05% metformin (PC), Coconopsis lanceolata extract group (UCL). After 5 weeks of feeding, average body weight of the UCL group mice was slightly decreased, while that of the HFD group significantly increased) Also, liver and adipose tissue weights in the UCL group significantly increased. The levels of trigliceride (TG) and total in the plasma of UCL-supplemented group were significantly lower than those of high fat diet group. On the other hand, HDL-cholesterol level was increased. Expression level of proteins related with adipogenesis such as SREBP-1c, ACC, and FAS in the liver of the UCL group mice was much lower comparing with the HFD group mice. In conclusion, the results showed that the Coconopsis lanceolata extract possesses significant antihyperlipidemic effects in C57BL/6J mice.
