Angelicae gigantis radix is the root of the perennial plant, which belongs to the family Umbelliferae. However, this herbal drug is represented quite different chemical components according to its different genus name, though other herbal drugs (i.e. Leonuri Herba, Xanthii Fructus and so on) show similar constituents on the same name. The root of Angelica gigas containing the coumarin compounds is commonly used in Korea, while Angelica sinensis and Angelica acutiloba including phthalide compounds are used in China and Japan, respectively as Angelicae gigantis radix. In this paper, a nearinfrared spectroscopic method was developed to determine genus name of Angelica spp., especially A. gigas and A. sinensis which are commonly misused in herbal markets. X-ray fluorescence spectrometry and electronic nose have been also applied as nondestructive methods to discriminate A. gigas from A. sinensis according to their specific properties.

This study was conducted to investigate the effect of sta-green and activated carbon on leaf and stem growth of Agastache rugosa as it is affected by different amounts of sta-green and activated carbon. The results obtained are summarized as follows. Growth characteristics including plant height and leaf number were the highest when treated with 30% of sta-green. The weight of fresh leaf and stem of Agastaches rugosa was very low in control. Also, fresh weight of Angelica acutiloba was higher in 10% treatment of activated carbon. However, when the plants were grown in 10% activated carbon. all these promoters were the biggest. Sta-green and activated carbon can be utilized as a soil conditioner in agricultural crop areas.

For the determination of principal taste components in L. chinensis M., A. acutiloba K., S. chinensis B. and A. sessiliflorum S., which were extracted with water and ethanol, contents and composition of free sugars, free amino acids, non-volatile organic acids and tannins were analyzed. The extraction yield of them was high when using the water as an extraction solvent, the optimal ethanol concentration with high yield was in the range of 50-75%. The contents of free amino acids in their extract $(25^{\circ}Bx)$ was high when using the ethanol as the extraction solvent. The amino acid content was in the range of 123-159 mg%. in samples. The free sugar of extracts contained 2-12% in samples which were consisted of glucose, fructose and sucrose. The pH and acidity range of extracts were 4.4-5.1 and 1.01-2.27% respectively, and especially extracts of S. chinensis B. showed to be strong acid as pH 2.9 and addity 11.93%. The composition of non-volatile organic acid in extracts of S. chinensis B. contained citric acid and malic acid 3.90% and 3.92% respectively as major components. The tannin content of extracts was considerably high when extracting with 50% ethanol, especially A. sessiliflorm S. contained $3.35%{\sim}3.85%$.

The dried root of Angelica species is used in traditional Chinese medicine in East Asia, particularly in Korea, China and Japan. Since the plant origin differs in these countries, they are often misused or adulterated in the commercial markets, resulting in distrust among the consumers. Enormous efforts have therefore been focused to distinguish the origin for the Angelica genus, by using morphological or cytogenetical analyses, and chemical markers based on biochemical analyses of secondary metabolites. DNA is considerably stable against different cultivation conditions, and to treatment and processing after harvesting of plants. Hence, several researches have been filed for the development of molecular markers, based on the single nucleotide polymorphisms in specific regions of DNA. However, there are several obstacles for application in the commercial markets, concerning the reproducibility, accuracy, sensitivity, and rapidity of these tests. In this review, we summarize the research achievements that help classify the origin of Angelica species, in particular, Angelica gigas Nakai. A. sinensis(oliv.) Diels, A. acutiloba Kitag., and A. acutiloba var. sugiyamae Hikino. Further researches are required for practical applications.

This research was attempted to prove suppressing effect of medicinal plants on the intestinal absorption of toxic heavy metals. In vitro study was performed by membrane filtration considering intestinal absorption conditions. From drinking water contaminated singly with 10 and 50 times level of water quality standard for heavy metals, the removal ratio of lead was $40{\sim}60%$ by Chicorium intybus, Angelica acutiloba and Ganoderma lucidium. And the removal ratio of cadmium was $20{\sim}40%$. The removal ratio of lead contaminated with both was $30{\sim}50%$ by every sample similarly, the removal ratio of cadmium was $10{\sim}30%$. The removal ratio of Angelica acutiloba was more higher than Chicorium intybus and Ganoderma lucidium. Considering the extraction conditions of samples, $70^{\circ}C$, 2 min conditions were higher than $95^{\circ}C$, 10 min conditions, the removal ratios of heavy metals were similar. And the membrane filter permeated the material under 500 mw selectively, so the final filtrate could regard as passive transport in intestinal absorption. In conclusion, this research exhibited that the medicinal plants beverages have a suppressing effect on intestinal absorption of lead and cadmium in drinking water.

For discrimination the origins and the commercial herb medicines of three Angelicae Radixes (Danggui), anatomical characters of leaves, petioles, and root cross-section were investigated and those were compared each other. The key for discrimination of these herb medicines was made by below simple characters: development of periderm, absent and present of collenchyma under the periderm, and distribution of latex tube in cortex. The result of discrimination for the commercial herb medicines based on the discrimination key, Angelicae gjgantis Radix (Angelica Gigas Root), Angelicae Radix (Japanese Angelica Root), and Radix Angelicae Sinensis (Danggui) were correctly identified for Angelica gigas Nakai, A acutiloba Kitagawa, and Angelica sinensis (Oliv.) Diels., respectively. Consequently, anatomical characters could be utilized for useful method to discriminate three Angelicae Radixes (Danggui).

This study was conducted to analyze ripening characteristics of the seed according to days after flowering. The seeds were harvested on land located in the Department of Herbal Crop Research in Rural Development Administration in 2019. Seed weight and germination rate were investigated according to days after flowering and the embryo:seed ratio was examined during the fruiting process. The results showed that the weight increased significantly by the days after flowering at each inflorescence and the seed began to germinate at different time. Further, given the embryo:seed ratio, we found that embryo continue to grow in the seed. Because Angelica acutiloba (Siebold & Zucc.) Kitagawa bloom in various inflorescences, the stage of embryonic development of the seeds can affect the germination of seed. Based on our results, the key seed harvest period for good seed is 50 to 70 days after flowering.

Disturbance of antioxidant system is very common in chronic alcoholics and herbal or natural products with antioxidant activity have been used for its treatment. This study was to investigate the effect of Vitis vinifera extract(V), Schisandra chinensis extract(S), Taraxacum officinale extract(T), Gardenia jasminoides extract(G), Angelica acutiloba extract(A) and Paeonia japonica extract(P), and their combinations on the antioxidant and ethanol oxidation system. Male Sprague-Dawley rats were subjected to Lieber-DeCarli ethanol liquid diet(ED) and were then given different herbal extract mixtures for 6 weeks including VST(V 100+S 150+T 150mg/kg/day), VSG(V 100+S 150+G 150mg/kg/day), VTG(V 100+T 150+G 150mg/kg/day), and VAP(V 100+A 150+P 150mg/kg/day). When the activity of alcohol dehydrogenase(ADH) and acetaldehyde dehydrogenase(ALDH) were compared between ED only group and herbal extracts treatment group, the differences were statistically significant. Phase I and II(glutathione-S-transferase, phenol sulfatransferase) enzyme activities were found to be significantly higher in the VAT treatment group compared to the ED group. Herbal extracts not only repressed the ethanol-induced elevation of malondialdehyde level, but also protected against ethanol-induced decrease in glutathione content, glutathione reductase, glutathione peroxidase, catalase and superoxide dismutase activities. The administration of the herbal extracts was found to be effective in eliminating lipid-peroxides induced by long-term consumption of alcohol by activating various enzyme systems and physiological active compound formation system. After a chronic consumption of alcohol, Angelica Radix protected the liver via activating the ethanol-metabolism enzyme system, and Paeoniae Radix via activating the ethanol-metabolism enzyme and the phase I, II-metabolism enzyme system. Taraxaci Herba was also effective in liver protection via activating the ethanol-metabolism enzyme system and the phase I, II-metabolism enzyme system, Gardeniae Fructus via activating the phase II-metabolism enzyme system and the anti-oxidation system enzyme, and Schisandra Fructus and a grapestone via activating the anti-oxidation system. Our data suggest that these herbal extracts may be useful as a health functional food or new drug candidate for fatty liver and hepatotoxicity induced by chronic alcohol consumption.
