Baicalein and Baicalin from the Radix of Scutellaria baicalensis Georgi Inhibits Oxidative DNA Damage and Apoptosis via its Antioxidant Activity
Garcia, Nellie Ann S. ; Jeong, Hyung-Jin ;
Korean Journal of Plant Resources, volume 22, issue 6, 2009, Pages 489~497
In this study, we evaluated and compared the protective effects of two major constituents, baicalein and baicalin, against oxidative DNA and cell damages caused by hydroxyl radical. Antioxidant properties were evaluated using DPPH and hydroxyl radicals scavenging assays and
174 RFI plasmid DNA and intracellular DNA migration assay were used to evaluate the protective effect against oxidative DNA damage. Also, MTT and lipid peroxidation assays were used to evaluate their protective effects against oxidative cell damage. Both baicalein and baicalin prevented intracellular DNA and cells from oxidative damage caused by hydroxyl radical via antioxidant activities. Baicalein demonstrated a stronger antioxidant activity in scavenging DPPH radicals and chelating
while baicalin scavenged hydroxyl radicals more efficiently. The differences in the level of baicalein and baicalin pose a different pathological pathway for each. The antioxidant activity of baicalin was due to its ability to scavenge hydroxyl radical whilst baicalein was a stronger
chelator. Further investigation to compare the molecular mechanisms of antitumor activities of baicalein and baicalin is vital to anticancer research.

The plant Agastache rugosa Kuntze has various physiological and pharmacological activities. Especially, it has been regarded as a valuable source for the treatment of anti-inflammatory and oxidative stress-induced disorders. However, little has been known about the functional role of it on oxidative damage in mammalian cells by ROS. In this study, we investigated the DPPH radical, hydroxyl radical, hydrogen peroxide and intracellular ROS scavenging capacity, and
chelating activity of the extracts from Agastache rugosa. In addition, we evaluated whether the extract can be capable of reducing
-induced DNA and cell damage in NIH 3T3 cells. These extracts showed a dose-dependent free radical scavenging capacity and a protective effect on DNA damage and the lipid peroxidation causing the cell damage by
. Therefore, these results suggest that Agastache rugosa is useful as a herbal medicine for the chemoprevention against oxidative carcinogenesis.

To study the effect of genotype of donor plants on anther culture, anthers of nine hybrid cultivars (Derby, Special, Bossanova, Minipaprika, Fiesta, Boogie, Phenlene, Kufrah, and Clarity) of sweet pepper (Capsicum annuum L.) were cultured in a petridish containing C medium (Sibi, Dumas De Vaulx medium) supplemented with 0.1 mg/L 2,4-D and 0.1 mg/L kinetin, 3% sucrose and 0.32% Phytagel. The cultures were incubated in the dark at
for seven days, and then cultured at
with a photoperiod of 16 hr. daylength for 40 days. Frequency of callus formation and plant regeneration was varied among cultivars. Callus formation was ranged from 6% in Phenlene to 69.8% in Kufrah. The highest percentage of regenerated plantlets was obtained in cv. Phenlene (2.67%) followed by Bossanova (2.41%). Result of ploidy analysis; chromosome number observation and flowcytometry analysis, showed that haploid plants could be developed from all of these hybrid cultivars except cv. Fiesta, where highest percentage of haploid plants were obtained in Minipaprika (40%) followed by cv. Bossanova (36.1%). Haploid plants derived from these hybrid cultivars contained single set of chromosome (12 in numbers), higher stomata density (numbers), and smaller sized stomata as compare to diploid plants. The mean length of stomata was 26.9
in haploid plants and 35.7

Seed mustard is high in nutrient quality and grows continuously under cold condition. Accordingly, it possessess high potential to bring about more efficient use of land when it is grown as a seasonings crop at paddy field in winter season. Recently, Seed mustard has aroused people‘s interest as a catch crop. The purpose of this trial is to examine productivity and chemical components of seed mustard and to select suitable variety in the southern area of Korea. Seed-mustard cv. Yeongsanpo local showed higher seed yield than any other varieties used in the experiment. It showed relatively high content of Oil, Protein, Ash, Carbo,
, Ca and T-N. The heritabilities of all the characters were estimated to be high. Therefore, it was concluded that Youngsanpo local was the most suitable variety with high yield and high nutrient quality at the southern area of Korea.

High productivity of ginger (Zingiber officinale Roscoe) was obtained from the rhizome produced by shoot-tip culture with Korean native variety, Seosanjong. Seed rhizomes induced by shoot-tip culture were successfully established in the field. The rhizomes induced by both plant or rhizome were higher in emergence rate and faster in days to emergence than those of home seed production. The seed rhizome production induced by shoot-tip culture was two times heavier than that of home seed production. These results suggest that shoot-tip culture might be one of mass propagation methods in seed rhizome of ginger plant.

Gou, Xiaoxia ; Kim, Jae-Hak ; Hong, Soon-Kwan ;
Korean Journal of Plant Resources, volume 22, issue 6, 2009, Pages 522~527
Plants of the genus Taraxacum are well-known as a traditional herbal remedy with a long history, and they have also been extensively used as food, chemicals and cosmetics. In this study, four Taraxacum species distributed in Korea (T. mongolicum, T. officinale, T. mongolicum variation and T. officinale variation) were utilized for an efficient method for direct multiple shooting induction and regeneration, using leaf blade, transition zone, petiole and root as explants in MS media with various hormone concentration and combination. MS medium containing IAA 0.2 mg/L and TDZ 1.0 mg/L showed the highest induction frequency of all the hormone combinations. Besides, the induction of T. mongolicum variation was most effective comparing with the other three species by the average induction frequency of four explants. While the induction effect of leaf blade explant was more obvious than the other three explants. This system exhibited a rapid propagation of shoots from the leaf blade explants and makes it convenient to make use of these Taraxacum species to develop their diverse applications in the future.

The study of germination and seedling growth characteristics of Neem under different soil and environment conditions was undertaken. The seed germination started 8 days after sowing in commercial bed soil, whereas, delayed germination was observed in sandy-loam (15 days) and sandy (19 days) soil. The highest germination (73.33%) was observed in commercial bed soil in green house, whereas, the lowest germination was observed in sandy soil (16.67%) and sandy-loam soil (8.33%). The seeds in the open field (sandy soil) also showed poor (10%) germination. The mean number of germination seed/day (GD) and seed germination vigor rate (GV) both were highest in the commercial bed soil with 0.733% and 16.67% respectively in the green house, whereas sandy and sandy-loam soil in green house and open field (sandy soil) all showed much lower GD and GV values. The seedling characteristics of nursery revealed that the seedling grown in the growth chamber in commercial bed soil was significantly higher in all the parameters comparing to others grown in green house and open field. The growth was nearly 7 fold in the chamber compared to that of the green house nursery observed in three months old seedlings. Likewise, HPLC analysis revealed that the green house grown seedling contain higher quantity of pigments compare to the chamber grown seedlings. Among the soils used the commercial soil alone or in combination with sandy and sandy-loam soil in the ratio of 2:1:1 respectively with the temperature of
showed better for Neem nursery preparation.

The time of seed collection is regarded as one of major concerns to obtain sound seeds. The physical and germinal aspects of Cryptomeria japonica D. Don (Taxodiaceae) seeds were analyzed to determine the optimum harvesting time in Korea. Cones were picked every 10 days from the
of July to the
of October in both 2005 and 2006. Seeds were collected from picked cones. Seed size and weight were not significant in two consecutive years. The 1,000-seed weight was 3.3 g for cones picked at the
of August and 5.3 g for cones picked at the
of September. The size of seeds was increased as the time of collection from the
of August to the
of September: from 19.3 mm to 21.3 mm in length and from 15.8 mm to 18.5 mm in width. Average germination rates in 2005 was 18.3% and 19.6% in 2006. The highest germination rate was 34.3% from seeds collected at the
of September in 2005. In 2006, the highest germination rate was 31.7% for seeds collected at the same date as the 2005 seeds. After the end of September, germination rate was decreased in both years. The results implied that the best cone picking time for Korean C. japonica seeds is around the end of September.

Aloe (Aloe vera L.), cucumber (Cucumis sativus L. var. tuberculatus Gabaj.) and sponge.gourd (Luffa cylindrica L.) are well utilized in Asian countries as traditional medicines and cosmetics, or foods. And we carried out an experiment to see if there are some specific ratios among trace metals on the plants. Though the metal concentrations varied significantly depending on the sampling periods, aloe gel is high in iron (Fe) and calcium (Ca). Cucumber fruit juice is also high in iron (Fe) and potassium (K). Sponge.gourd sap contains a high amount of zinc (Zn) and calcium (Ca). The uses of the previous 3 plant parts are considered to have some relations to their different ratios and of their trace metals.

We examined the growth characteristics, fresh tuber yield, rotenone content of two yam beans (Pachyrhizus erosus and P. ahipa) introduced from Mexico. P. erosus species showed better adaptable ability than P. ahipa species in seed productivity and tuber yield. Rotenone content in the P. erosus species extracted with chloroform was 3.6 folds much more extracted than ethanol extraction. The order of rotenone content found in crude extract obtained by different solvent extraction from the highest to the lowest was mature seed (484.7
) and leaves (17.2
) of the P. erosus species, respectively.

Allicin, a garlic componente, is believed to provide protection against various diseases including inflammation. Since interactions of the cell adhesion molecules are known to play important roles in mediating inflammation, inhibiting adhesion protein upregulation is a possible therapeutic target. In this study, we demonstrate that TNF-
- and catalase-induced expression of ICAM-1 on human lung epithelial cells (A549) in a dose-dependent manner and catalase expression and activity were also increased in TNF-
-treated cells. Treatment of the TNF-
-treated cells with catalase inhibitor 3-amino-1,2,4-triazole resulted in a significant decreased the level of ICAM-1. These data suggest that induction of ICAM-1 expression by TNF-
is associated with catalase. In addition, allicin was found to inhibit the TNF-
induced expression of ICAM-1 on the A549 cells. This compound also inhibited the production of catalase induced by TNF-
, which suggests that the inhibition of ICAM-1 expression by allicin may be due to the modulated production of catalase.

Adventitious root culture was established in the Jawahar variety of Withania somnifera using MS basal medium supplemented with 0.5 (mg/l) IAA and 2.0 (mg/l) IBA. Root tips from germinated seedlings, MS0 maintained plants and adventitious roots were maintained in suspension medium (1/2 MS basal medium supplemented with 3% sucrose) for a period of 1 to 6 months. The weight gain in roots was noted and the withanolides were extracted from the dry roots using solvents petroleum ether, 50% ethanol and chloroform. The withanolides in the chloroform fractions of all root samples analyzed were compared using thin layer chromatographic analysis. Withanolide content in adventitious root sample was found to be superior compared to other roots at any given point of time during the 6month growth period.HPLC analysis of in vitro adventitious roots showed the presence of a new compound.
