Kang, Jin-Ho ; Shim, Young-Do ; Jeon, Byong-Sam ;
Korean Journal of Medicinal Crop Science, volume 10, issue 2, 2002, Pages 75~81
Indoor seed treatments to elevate seedling emergence should be of value. The study was done to model the presown treatments of Platycodon grandiflorum seeds by evaluating the treatment effects of priming,
, drying and water imbibition after drying on their germination and then their successive seed treatments on the basis of its seedling emergence. after priming using
treatment under their different concentrations and light quality illuminated for 12 hours a day were done separately and their two best results were compared to determine the better one, drying of imbibed seeds using the above best result and water imbibition of the dried seeds were successively done to check the rates of germination and emergence. In each treatment of priming and
, the former best germination occurred at
150 mM done under 2 day darkness but the latter one did at 0.01 mM done under 12 hour a day red light forced for 3 days. Of the two best results from priming and
treatments, the latter result was shown higher germination rate.
treated seeds were best desiccated under
and 4 hour red light illumination. The germination rate of seeds dried after
treatment was enhanced as imibibed 2 days immediately before sowing. Seedling emergence of all 3 successive treatments,
, drying and water imbibition before sowing was the greatest than the two others, only
treatment and the combination of
and drying, in which indicated that its presown seed treatment must follow the successive procedure of the above 3 ones.

Korean Journal of Medicinal Crop Science, volume 10, issue 2, 2002, Pages 82~87
This study was conducted to investigate the influence of shading treatment on the photosynthetic rate, transpiration rate, stomatal conductance and its any correlations in Liriope platyphylla
. Followings were achieved as a conclusion. The net photosynthetic rate was increased as the PAR was increased and reached maximum at the
of PAR in all of leaves, also this treatment caused a higher net photosynthetic rate in comparison with control. It shows the tendency of increasing stomatal conductance caused by the increment of PAR. The diurnal changes of photosynthesis, transpiration rate and stomatal conductance were increased as the PAR was increased in the morning, but they indicated a decreased tendency in broad day. The relationship between net photosynthetic rate and stomatal conductance is well fit by the first regression linear equation. However, the values obtained from the linear equation have the different, respectively, and have highly significance. From the above results, net photosynthetic rate of shading treatment is higher than control in the same stomatal conductance. Different first regression linear equation were obtained between the transpiration rate and stomatal conductance, photosynthesis and stomatal conductance in during the control and shading treatment, too.

This study was designed to investigate the pharmacological effects of glasswort. SD rats drunk experimental water (added to glass wort extracts) for 4 weeks. Weight gain resulted in reduced by administration of glasswort extracts compared with control group(p < 0.05). Total protein and albumin contents in serum of SD rats for 4 weeks did not show significantly difference by administration of glasswort extracts compared with control group. GOT was
and GPT was
by administration of glasswort extracts in SD rats for 4 weeks. Total and LDL cholesterol contents in serum of SD rats significantly decreased by administration of glasswort extracts compared with control group(p < 0.05) HDl cholesterol contents in serum of SD rats was significantly increased by administration of glasswort extracts compared with control group(p < 0.05). Total lipid and triglyceride contents in serum of SD rats was significantly decreased by administration of glasswort extracts compared with control group (p < 0.05). The overall results suggest that the administration of glasswort extracts can not only prevent a disease of arteriosclerosis, hyperlipidemia, fatty liver but also inhibit of weight gain.

The immune activation activities of ethanol, ethanol : water(1 : 1,v/v) and water extracts from Dendropanax morbifera Lev. were compared. The crude extracts showed relatively low cytotoxicity as less than 26% by using human normal liver cell(WRL-68). For example, the ethanol extract inhibited. in MCF7 and Hep3B cells in adding 1.0 mg/mL ethanol extracts. The growth of human immune T and B cells was enhanced up to
times by adding the crude extracts. These are a trend of increasing secretion of
from human B/T cell for 6 day cultivation. It was found that the immune activation activities of the crude extracts seemed to be higher than those obtained by using other solvents.

This study was carried out to find the possibility of use of Solid Phase Microextraction (SPME) for extracting the volatile aroma compounds in the five aromatic plants (Agastache rugosa O. Kuntze, Mentha arvensis Linne, Thymus quinquecostatus Celakovsky, Elsholtzia splendens Nakai, Schizonepta tenuifolia Briquet) belongs to the Labiatae. In the result of the analysis, the volatile aroma compounds were mainly composed monoterpene alcohol (linanol, menthol,
, borneol), monoterpene ketone (limonene, menthone) and sesquiterpene (trans-caryophyllene,
. The volatile aroma compounds of Agastache rugosa O. Kuntze and Mentha arvensis Linne were extracted by SPME more identified than the SDE. However, Schizonepta tenuifolia Briquet more identified by the SDE and in Elsholtzia splendens Nakai similar to the SDE. Especially, the SPME showed the sesquiterpene contents was more than the SDE. The major volatile aroma compounds were difference but the composition of those between the SPME and the SDE showed no difference. Within the results, the SPME showed the most convenient and a rapid extraction method to analysis of the volatile aroma compounds.

This study was performed to determine the antimutagenic and cytotoxic effect of ,Kalopanacis cortex endothelium. Methanol extract was used on Salmonella typhimurium TA98, TA100 and three cancer cell lines. In the Ames test, methanol extract of Kalopanacis cortex endothelium alone did not exhibit any mutagenicity but showed substantial inhibitory effects against mutation induced by 4-nitroquinoline-l-oxide(4NQO), N'-methyl- N'-nitro-N-nitrosoguanidine(MNNG) and benzo(a)pyrene(B(a)P). The methanol extract of Kalopanacis cortex endothelium showed approximately 79.29% and 75.38% inhibitory effect on the mutagenesis induced by 4NQO and B(a)P, respectively, against TA98 strain. Whereas 79.49%, 89.3% and 68.85% inhibitions were observed on the mutagenesis induced by 4NQO, MNNG and B(a)P against TA100 strain. Methanol extracts from Kalopanacis cortex endothelium showed high antimutagenic effects against 4NQO, MNNG and B(a)P. The anticancer effects of methanol extract from Kalopanacis cortex endothelium against human lung carcinoma(A549), human breast adenocarcinoma (MCF-7) and human hepatocellular carcinoma(Hep3B) were investigated. The treatment of 0.5mg/ml Kalopanacis cortex endothelium methanol extracts had the highest cytotoxicity against A549(81.54%), followed by MCF-7(81.92%) and Hep3B (78.57%). In contrast 0.5mg/ml treatment of methanol extracts from Kalopanacis cortex endothelium had only
cytotoxicity on normal human liver cell(293).
