Winter bud explants from 15 individual angelica tree (Aralia elata) were cultured in vitro to find out optimal conditions for somatic embryo induction as well as plant regeneration. Calli are induced and grown on MS medium supplemented with 1.0 mg/L 2,4-D for 4 weeks and subcultured on a half-strength MS medium without phytohormones to induce somatic embryos. Inter-simple sequence repeat (I-SSR) markers were analyzed with total DNAs extracted from the trees. Genotype effects on somatic embryo induction were examined by cluster analysis. Callus induction rate varied from 58.5 to 100% among the genotypes. Somatic embryo induction rate also greatly varied from 0 to 100% among the genotypes. There was a significant difference in somatic embryo induction rate even among the individual trees that showed close genetic relationships each other. This suggested that somatic embryo induction rate in Aralia elata be influenced by a few major specific genes rather than whole genomic similarity among individual trees. Four individuals of Ulneong-7, Cheju-1, Shingu and China, which are recalcitrant to somatic embryo induction, turned out to have a close genetic relationship, suggesting that both physiological and genetic factors affect somatic embryo induction. The results suggest that genotype selection be the most important factor to achieve an efficient propagation, although cultural optimization through medium and explant manipulation may also play crucial roles in somatic embryogensis as well as plant regeneration of these species.

This study was conducted to investigate the potential acute toxicity of Aralia elata by a single oral dose in ICR mice. Thirty mice of each sex were randomly assigned to three groups of 10 mice each. The test articles were administered once by the gavage to mice at dose levels of 0, 2,500 and 5,000 mg/kg body weight. The mortality and changes on body weight and clinical signs of gross observation were monitored for 14 days after dosing. At the end of 14-day observation period, all animals were sacrificed and complete gross postmortem examinations were performed. There were no dead animal and adverse effects on clinical signs, the body weight and the gross finding. As the results, we could not find any toxic effect at the dose levels of 2,500 or 5,000 mg/kg in mice and the minimal lethal dose was considered to be over 5,000 mg/kg body weight in mice.

In a preliminary screening of the plant extracts for the antigastritic action in rats, the extract of Aralia elata(Araliaceae) showed positive activity in HCI plus ethanol induced gastric lesion. Systematic fractions with hexane, chloroform, ethyl acetate and butanol resulted in the most patent activity with the butanol fraction: This butanol fraction at the oral dose of 200 mg/kg exhibited significant inhibition of absolute alcohol induced gastric lesion which was more potent than 100 mg/kg of cimetidine and had significant stimulation of mucus secretion. The butanol fraction showed significant decreases in the ulcer indices of Shay ulcers and inhibition of gastric juice secretion with acid output in pylorus-ligated stomachs of rats. It also suppressed the acetic acid induced gastric ulcer. These results might suggest that the butanol fraction had inhibitory action in gastric lesion and ulceration through inhibition of gastric acid secretion and stimulation of mucin secretion in the stomachs of rats.

From the root barks of Araila elata Seem.(Araliaceae) three known saponins together with oleanolic acid and $\beta$-sitosterol $3-O-\beta$-D-glucoside were isolated. The saponins were identified as oleanolic acid $28-O-\beta$-D-glucoside were isolated. The saponins were identified as oleanolic acid $28-O-\beta$-D-glucopyranosyl ester, oleanolic acid $3-O-\beta$-D-glucuronopyranoside and oleanolic acid $3-O-\alpha$-L-arabinofuranoysyl-(1$\rightarrow$4)-$\beta$-D-glucuronopyranoside(narcissiflo on the basis of chemical and spectra data. The latter two saponins were isolated as their dimethylesters as well as monomethylesters.

In this study, we aimed to evaluate the quality of Aralia elata shoots according to different packaging methods during storage at 2℃. The highest level of dehydration and wilting incidences were observed in polypropylene containers with polyvinyl chloride wrap (PP+PVC), and these levels continually increased during the entire storage period, compared to other packaging methods. The overall marketability of A. elata shoot packaged in polyethylene terephthalate container (PET) and PP with the mineral-coted functional warp (PP+F) constantly declined during storage with a similar level of 38.6 and 36.0% at 15 days in storage, respectively. PP with PET cover packaging (PP+PET) showed the lowest decay and wilting rates during the entire storage, and the wilting score at 10th day was 51.9, 58.0, 51.8% suppressed, as compared to PET, PP+PVC, and PP+F, respectively. Consequently PP+PET packaging effectively decreased the deterioration of A. elata and maintained marketability for 10 days of storage at 2℃.

BACKGROUND: In this study, shoots of Aralia elata and Kalopanax pictus which belong to the Araliaceae family were analyzed using UPLC-DAD-ESI(+)-QToF/MS to characterize of individual phenolic acids. METHODS AND RESULTS: Total thirteen phenolic acids were identified, and nine hydroxycinnamic acid derivatives have been identified for the first time in shoots of Aralia elata and Kalopanax pictus. For total phenolic acid content (mg/100g dry weight), shoots of Aralia elata and Kalopanax pictus showed 754.8 and 845.3 mg/100g, respectively. 5-O-Caffeoylquinic acid (49%) and 3,5-di-O-caffeoylquinic acid (44%) were found as major phenolic acids in Aralia elata, while 5-O-caffeoylquinic acid (91%) was a major component in Kalopanax pictus. CONCLUSION: On comparing the two plants, it was considered that the biosynthesis of 3,5-di-O-caffeoylquinic acid can be affected by 5-O-caffeoylquinic acid in Aralia elata.

This study was performed to analyze the physicochemical and sensory properties of Acanthopanacis cortex and Aralia elata according to their blanching conditions and thawing methods. In terms of their Hunter colors, the A. cortex and A. elata that were blanched without adding salt to them for 7 min and 4 min, respectively, had the highest L values. The chlorophyll content (148.7 mg%) of A. cortex that was blanched with 1% salt for 4 min was higher than those of the other samples, and the chlorophyll content of A. elata was 32.4 mg% when it was blanched for 4 min without salt addition. The sensory test results showed the highest overall preference for the sample that was blanched without salt for 4 min among all the samples. The Hunter color of A. cortex did not significantly differ with different thawing methods, but the value of A. elata that was thawed in a microwave oven was higher than those of the other samples. The chlorophyll contents of A. cortex and A. elata that were thawed in a microwave oven were the highest among all the samples. As for the overall preference for the samples according to the thawing method, A. cortex and A. elata scored highest in the case of thawing at $25^{\circ}C$ and in a microwave oven, respectively.

Aralia elata (Miq.) SEEM is a deciduous shrub that has attracted attention as a high-income forest product. To improve the efficiency of cultivation and increase income, productivity according to the pruning period and annual pruning after harvesting Aralia elata shoots was analyzed. The optimal time was determined by pruning five times at 2-week intervals from 6 days after shoot harvesting. To investigate the pruning effect, pruning was performed at 30 cm from the ground in the first year after planting. From the second year after planting, branches grown for 1 year were pruned to 10 cm, and the annual shoots and branches were compared. Thenumber of first pruned branches after 6 days was 1.3-2.1 times higher after shoot harvesting than at other times, and the shoot characteristics were 1.2-1.7 times better than those at other periods. The faster the pruning, the better the quality of the harvested shoots. Annual pruning produced high-quality shoots (approximately 1.5 cm in diameter and 16 cm in length) from the second year after planting, and it was possible to increase productivity by inducing generation of branches capable of harvesting shoots. Annual pruning also made it possible to maintain easy shoot harvesting at approximately150 cm. These results showed that it was efficient to perform Aralia elatapruning as early as approximately 6 days after shoot harvesting. Pruning enabled production ofuniform-quality shoots every year and increasedthe yield of the trees.
