  • Four thymol derivatives, 2,5-dimethoxythymol (1), 2-methoxythymol isobutyrate (2), 10-isobutyloxy-8,9-epoxythymolisobutyrate (3) and 10-(2-methylbutyloxy)-8,9-eposythymolisobutyrate (4) were isolated from the aerial parts of Carpesium divaricatum. the structures were elucidated by high field 1D and 2D NMR techniques.

  • The spacing between plug cells and cell volume of each plug cell for nursing tomato seedlings were studied to know the effects on seedling growth and early yield. There were four treatments. The spacing of plug cells was done (OK) or not (NO) in case of cell spacing. The cell number in a plug tray was set to 40 or 50 in case of cell volume. The growth environment and irrigation regime were the same in all of the treatments during the experiment period. The photosynthetic rates, seedling qualities, yield and yield speed were significantly affected by both of the treatments. The photosynthetic rates and seedling qualities were the best in 40S-OK following by 50S-OK, 40S-NO, and 50S-NO while the yield was the best in 40S-OK following by 40S-NO, 50S-OK, 50S-NO. It means the spacing gives more impact than the cell volume in the stage of nursing but the cell volume gives more impact than the spacing after the stage of nursing. In the conclusion the spacing of plug cells in appropriate nursing stage is needed with the appropriate cell volume to make high quality of seedlings and high yield.

  • Three diterpene alkaloids, songorine (1), neoline (2), N-deethylneoline (3), were isolated from Kyong-Po Buja (Processed Aconitium carmichaeli, Ranunculaceae) which was used as Chinese traditional medicine with analgesic, anti-inflammatory and cardiotonic activity. Their structures were established by chemical and spectroscopic methods.

  • Four steroids and one flavonol glycoside were isolated from the ethanol extract of the whole plant of Aconitum pseudolaeve var. erectum. Their structures were identified as ${\beta}-sitost-4-en-3-one$, 22-dihydro-stigmast-4-en-3,6-dione, ${\beta}-sitosterol$, ${\beta}-sitosterol-3-O-{\beta}-D-glucopyranoside$ and $kaempferol-3-O-{\beta}-D-glucopyranoside(astragalin)$ on the basis of spectral data.
