Low quality fresh ginseng was fermented by Pheliuus linteus mycelium at
for 30 days, then extracted by water solvent at
for 180 min. On human normal cell lines (HEK293), cytotoxicity was about 10% lower in adding extracts of the fermentation ginseng than that from low quality ginseng. The fermented extracts also inhibited the growth of several human cancer cells. Among them, respectively, digestive organs related cancer cells, such as human stomach adenocarcnioma and human epithelial adenocarcinoma were most effectively inhibited up to 85% and 90%, respectively. Then, selectivities were in the ranges of 3 to 5, compared to 2 to 3 from low quality fresh ginseng. Generally, fermented ginseng extract showed higher anticancer activities as well as higher DPPH radical sacavening activity, possibly due to high contents of total phenolic components as 6.96 mg/g. It was very interesting that the fermented ginseng contained very higher contents of ginsenoside-Rc+
, compared to others in low quality fresh ginseng because of partition digestion of mycelium growth. The results can tell that low quality fresh ginseng can be utilized by the fermentation with Pheliuus linteus mycelium.

This study showed the increase of antitumor activities of water soluble E. sinica extract by nano-encapsulation process with lecithin. Five groups of lecithin only group (LO), lecithin nano-encapsulated E. sinica group (LE), E. sinica only group (EO), one negative control group (NCO) and positive control group (PCO) were set for several anticancer experiment and fed into Sarcoma-180 injected mice. The cytotoxicity of LE on the human normal kidney cell (HEK293) showed 14.8% lower than 19.2% of EO and 18.4% of LO. Growth of human liver carcinoma cell and human stomach carcinoma cell as representative of digestive system in vitro was inhibited up to about 85.1% and 87.3%, in adding 1.0 mg/
of LE, which values 15% higher than that from conventional EO. The survival rates of each mice group were 40%, 63%, 48%, 33% and 100%, respectively after 40 days of injecting Sarcoma-180. The increment of their body weights of the extract feeding groups was suppressed down to 10~15%, compared to the negative control. The nano-particles also reduced the hypertrophy of the internal organs such as spleen and liver down to 15~20%, compared to those as the other groups. Among them, LE effectively reduced the size of tumor form to 20%. From these results, in vitro and in vivo antitumor activities of E. sinica could be enhanced by using nano-encapsulation process with lecithin because of better permeation into the cancer cells by confocal observations.

Obesity has become one of the main public health problems. Saussurea lappa (Asteraceae), syn Aucklandia lappa and Saussurea costus, is a well-known herbal medicine that has been used for treating various ailments, such as inflammatory and gastrointestinal diseases. The present study examined the anti-obesity effect of S. lappa extract (SLE) in 3T3-L1 adipocytes and high fat diet (HFD)-induced obese mouse model. SLE significantly inhibited the differentiation from preadipocytes to adipocytes of cultured 3T3-L1 in dose-dependent manner. In addition, SLE significantly decreased the body weight gain and the food efficiency ratio of mice fed HFD during 9 weeks. Further study must be performed for the pharmacological mechanism and safety of SLE as well as the identification of active compound in SLE. Our results revealed that S. lappa suppresses the adipogenesis in cultured cells and the obesity in rodent models. Therefore, S. lappa may be useful toward the development of new potent anti-obesity drugs.

We investigated a method to improve anticancer activities of Acer mono wood extracts by ultra high pressure extraction process. The A. mono was extracted by water at
and 300 MPa for 15 min (High Pressure Extraction, HPE). The extraction yield by ultra high pressure extraction process was 5.42%. The cytotoxicity on human normal lung cell (HEL299) of the extracts from HPE showed 21.54% lower than that from conventional water extraction at
in adding the maximum concentration of 1.0 mg/
. Ultra high pressure extracts process for 15 minutes extracts (HPE15) showed more potent scavenging effect than the control, BHA. On SOD-like test, the HPE15 showed highest activity as 32.4% at 1.0 mg/
concentration. Human stomach adenocarcinoma, liver adenocarcinoma, breast adenocarcinoma and lung adenocarcinoma cell growth were inhibited up to about 67~79%, in adding 1.0 mg/
of extracts from HPE. HPE was 20~25% higher than conventional water extraction. It was interesting that, among several cancer cell lines (stomach adenocarcinoma, liver adenocarcinoma), the growth of digestive related cancer cells were most effectively inhibited as about 75~79%. On in vivo experiment using ICR mice, the variation of body weight of mice group treated A. mono wood extracts from HPE of 100 mg/kg/day concentration was very lower than control and other group. The survival times of group treated this extracts was 61.96% longer than that of the control group and this extracts showed the lower tumor weight, which were 10.49 g than positive control as 16.17 g. Based on these results, we could tell that the HPE wood extracts of A. mono had higher anticancer activity than conventional water extraction. The results of HPE showed obvious advantages in higher efficiency, shorter extraction time, at lower energy costs.

This experiment was carried out to investigate the effect of several organic compost on the growth and root yield of Scutellaria baicalensis G. with organic cultivation from 2008 to 2009. Four organic compost were used ; Rice bran compost (RC : 1.1-3.6-1.4), Wheat bran compost (WC: 1.1-3.4-1.4), Hangawi compost (HC : 3.7-4.0-1.0), Cheonnyeonjigi compost (CC : 12.4-3.4-5.4) and Fermented chicken droppings compost (FC : 2.9-6.1-3.2). Organic matter, available phosphate and
of soil increased in all plots with the addition of organic compost, specifically in HC, CC and FC application. Treatment of HC, CC and FC application increased emergence rate and improved the growth characters of shoot, root parts of plants compared to those of RC application. Subterranean part yields by different organic compost was high 149~156 kg per 10a as by growth increment of dried root yield. length of main root and diameter of main root. respectively, 17.4~18.4 cm, 12.65~12.94 mm from HC, CC and FC application. There were significantly positive correlation between the growth characters of shoot, root parts of plants, dry root yield in Scutellaria baicalensis G. grown under organic compost application.

This study describes an efficient approach to the development of DNA markers for use in distinguishing the Scrophularia species that have been used as useful medicinal crops. In order to distinguish Scrophularia species, DNA sequences of rpl-5 region in mitochondrial DNA of Scrophularia species were analysed for detecting sequence variations, and the PCR-RFLP method was applied for developing practicable DNA marker patterns. Several DNA variations were detected by the sequence comparison of rpl-5 region among Scrophularia species. Genetic relationship analysis of Scrophularia species was carried out based on these DNA variations. DNA variations of rpl-5 region were revealed that it was significantly efficient in genetic relationship analysis of Scrophularia species. In addition, Scrophularia species tested in this study were completely discriminated by four polymorphic genotypes by PCR-RFLP combined with Tsp509 I (^AATT) restriction enzyme. Our results suggested that DNA sequence variations of rpl-5 region were sufficiently useful for genetic relationship analysis of Scrophularia species. Polymorphic genotypes by PCR-RFLP using the Tsp509 I enzyme will be useful for discrimination of Scrophularia species as a practicable DNA markers.

We investigated genetic diversity among and within the populations of cultivated ginseng (Panax ginseng C. A. Meyer ) using SRAP profiles. A total of 24 ginseng plants were sampled from the three populations (two from China, one from Korea). Since all these populations are previously shown closely related to each other assister groups, we used Panax quinquefolium L. and wild ginseng as a reference species, which is not "within the sister group". All individuals from the three populations were screened with a total of 36 primer pairs with 26 primers generated from 328 SRAP bands of DNA gels. The mean gene diversity (
) was estimated to be 0.057 within populations (range 0.032-0.067), and 0.086 at the species level. The genetic differentiation (Gst=0.31) indicates that genetic variation apportioned 30% among populations and 70% within populations. Generally, the result of this study indicates that ginseng contains high molecular variation in its populations.

The chromosome number was identified and fluorescence in situ hybridization(FISH) mapping of 5S and 45S rDNAs were conducted for C. minima and C. lanceolata in the genus Codonopsis from Jeju island. In this study, we have confirmed that the somatic metaphase chromosome number determined as 2n=2x=16 was the same as the findings from the previous studies. While the conventional staining method makes it rather difficult to distinguish satellite chromosomes due to high degree of variability, FISH analysis produced the exact number and location of 5S and 45S rDNAs. Both species in the genus Codonopsis have a pair of 5S rDNA and their gene loci were observed on chromosome 3. Although two pairs of 45S rDNAs (one on chromosome 1 and the other on chromosome 8) were identified in both species, the 45S rDNA signals on chromosome 8 in C. minima were significantly weaker than those on chromosome 1. In addition, the 45S rDNA signals on chromosome 1 in C. lanceolata showed that the chromosome is non-homologus. In this study, we have determined cytogenetic characteristics of C. minima and C. lanceolata according to their gene replication patterns.

Anthocyanin and polyphenolic compounds present in fruits of mulberry (Morus alba L.) were determined and the influence of temperature and UV irradiation on stability of the anthocyanin-copigment complex were investigated. The copigmentation substance selected in non-anthocyanin fraction from mulberry for the study included: phenolic acid (hydroxybenzoic acid) and flavonoid (quercetin-3-O-
-D-glucopyranoside). The copigmentation effect increased with the copigment content. UV irradiation had a stronger degradation effect on the copigmentation complex than heating at
. The non-anthocyanin fraction of mulberry and isolated flavonoid (quercetin-3-O-
-D-glucopyranoside) from mulberry fruit predominated over other copigment substances.

This study was carried out to obtain the information on the antioxidant activity of Phyllanthus. We compared and analyzed three indigenous collections of Phyllanthus: species from Korea, Brazil and Paraguay. Total phenolic acid contents were
mg/mL in KCS (Korean Collection Species),
mg/mL in PCS (Paraguay Collection Species) and
mg/mL in BCS(Brazil Collection Species). In both DPPH radical scavenging activities and SOD-liked activities, KCS was the highest (
). KCS were also the highest in hydroxyl radical scavenging activities (
). It turned out that there was no meaningful difference between BCS (
) and PCS (
). As for hydrogen radical scavenging activities, there was no statistically meaningful difference between KCS (
) and BCS (
) and it was the lowest in PCS (
). Our results showed that KCS excelled the others not only in antioxidant activity but also in other beneficial effects. This encouraging results may be potentially useful in developing Phyllanthus urinaria L. variety which contains lots of functional elements such as total phenolic acid.
