Objectives : This study was designed to establish a characteristic discrimination of internal and external morphological standard of original plants and herbal states in Pogostemonis and Agastachis Herba. Methods : In this studies, the external-internal morphological standards were determined by using stereoscope and butanol series. Results : 1. The external characteristics: Pogostemon cablin has hairs and brown-like in stem, elliptical fruit. On the other hand, Agastache rugosa has no hairs and red-like in stem, obovatic trigone fruit. 2. The physical characteristics: Pogostemon cablin is gray in whole, has hairs in stem and numerous hairs of ash in leaf. On the other hand, Agastache rugosa is yellow-green in whole, has no hairs in stem. Specially the latter has deep-green colour and numerous hairs presenting mostly at lower epidermis in leaf. 3. The physical characteristics in currents: Pogostemon cablin is brown, has hairs and round-like stem. On the other hand, Agastache rugosa is green or yellow-green, has no hairs and tetragon in stem. 4. The internal characteristics: Pogostemon cablin has progressed spongy tissue in epidermal cell of leaf and many rank of epidermal cell in stem. On other hand, Agastache rugosa has I rank palisade tissue in leaf and few rank of epidermal cell in stem. In the external shape, it was possible that herbs were distinguished according to artificial cIassification and that same genus-degree of relatedness among herbs could be distinguished by more precise and active observation. In the shape of real herbs, I compared current herbs in market with original herbs which were just collected or were on the course of drying. In addition, it was possible that the internal shape could be identified by using microscope after butanol series. Conclusion : Though it was impossible to make distinction of herbs which are not current in my search contents, this search contents will be a standard for applying herbs in the future. An Additional standard establishment including physiochemical reaction and gene research is required in order to supplement the fault of this search.

A method for isolation and quantitative determination of patchouli alcohol from Pogostemonis Herba (Pogostemon cablin) has been developed. Isolation of patchouli alcohol was achieved by column chromatography employing the normal-phase gradient separation system n-hexane-ether on silica gel column. The GC method for quantitative determination of patchouli alcohol provided a method for standardization of the raw drug. It suggested that the average content of patchouli alcohol in Pogostemonis Herba is about 0.26%.

Pogostemonis and Agastachis Herba are the whole of Pogostemon cablin (BLANCO) BENTH or Agastache rugosa (FISCHER et MEYER) O. KUNTZE (family Labiatae) which is produced in all part of Korea and China. This drug is used for removing dampness by means of aromatics in oriental medicine. The standard formula of this drug is important from the viewpoint of the quality control. A characteristic discrimination of internal and external morphological standard in original plants and herbal states of Pogostemonis and Agastachis Herba are as follows. 1. The external characteristics: Pogostemon cablin has hairs and brown-like in stem, elliptical fruit. In the other hand, Agastache rugosa has no hairs and red-like in stem, obovatic trigone fruit. 2. The physical characteristics: Pogostemon cablin is gray in whole, has hairs in stem and numerous hairs of ash in leaf. In the other hand, Agastache rugosa is yellow-green in whole, has no hairs in stem. Specially the latter has deep-green colour and numerous hairs presenting mostly at lower epidermis in leaf. 3. The physical characteristics in currents: Pogostemon cablin is brown, has hairs and round-like stem. In the other hand, Agastache rugosa is green or yellow-green, has no hairs and tetragon in stem. 4.

In the present study, the substance that show anti-proliferation of cancer cells as well as anti-oxidant and anti-inflammatory effect was searched. As a results, the methanol extract of Pogostemon cablin (P. cablin), is a well-known herb for traditional medicine in Korea and China for treating the digestive disorders, less of appetite, vomiting and diarrhea, inhibited the growth of various cancer cells such as A549, HepG2, MCF7 and HT29 cells. Cytotoxic effect of methanol extraction of P. cablin was excellent in A549 cells. P. cablin extract induced cell cycle arrest at G1 phase of A549 in a dose dependent manner. And it induced phosphorylation of p38 and Cdc25A and reduced expression of Cdc25A, Cdks, Cyclins and phospho-Retinoblastoma (Rb) proteins. Therefore, P. cablin extract seems to act through the p38 - Cdc25A - Cdk - Cyclin - Rb pathway in A549 cells. In addition, P. cablin extract showed anti-oxidant effect by DPPH free radical scavenging assay and anti-inflammation effect by inhibition of lipopolysaccharide (LPS)-induced nitric oxide (NO) in RAW 264.7 cells in a dose-dependent manner. Taken together, these results suggest that P. cablin may be used as not only candidate materials for anti-cancer, anti-inflammatory and anti-oxidant, moreover, it would be possible utilized in various health functional food materials.

Objectives : The purpose of this study is to determine the original source of Gwackhyang(藿香) newly. Methods : Compare the growing district, figure and etc. of Gwackhyang included in the books on herbal medicine with those of present. Results : 1. The growing district of Gwackhyang is south of China or southern place than China. 2. In the picture of the leaf of Gwackhyang, its end is round and it is similar to Mori folium or the leaf of Solanum melongena. 3. We can propagate it by planting a piece of stem. 4. At the Dynasty of the Sejong king, japan sent it 18 times for diplomacy present, and according to Sejongsillockzirizi(世宗實錄地理志), it was planted for the test one time. 5. Baechohyang, another name of Gwackhyang, is rhizome and root of Anisochilus carnosus according to Bonchogangmok(本草綱目). Conclusion : Provide a basis for these results, Gwackhyang in the books on herbal medicine means Pogostemon cablin. It is a mistake to use Agastache rugosa in GwackhyangJeonggisan(震香正氣散) etc. in Korea.

The pharmacological rationale of Agastache rugosa (AR) or Pogostemon cablin (PC), which have been used in traditional Korean medicine to treat dampness pattern or syndrome in gastrointestinal tract, was investigated on the gastrointestinal disorders. In-vivo model studies that examined the effect on the gastrointestinal disorders of AR or PC were collected. They were classified into disease-induced in-vivo models or non-disease in vivo models. The target disease, animal species, induction method, administration, and outcomes (changes in morphological and histological parameter, or blood and fluid) of each study were analyzed. The therapeutic mechanism of AR or PC extract was evaluated by the induced diseases and the changes in outcomes. There were contradictory reports on gastrointestinal motility of AR or PC in disease non-disease in-vivo model. AR or PC inhibited gastrointestinal motility in disease model of increased gastrointestinal motility, while promoted motility in disease model of decreased gastrointestinal motility. AR or PC also inhibited inflammatory changes in gastrointestinal inflammation model. These results suggest that the bidirectional regulation of gastrointestinal motility and the improvement of gastrointestinal inflammatory disorders might underpin traditional therapeutic effect of AR or PC, that is effect to resolve dampness of gastrointestinal tract.

To develop a new natural whitening agent for cosmetics, we investigated the inhibitory effects of Pogostemon cablin Bentham extracts (PCE) and its active component on melanogenesis. PCE showed ROS scavenging activities in 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and xanthine/xanthine oxidase system with the $IC_{50}$ values of $24.2{\pm}2.85{\mu}g/mL$ and $IC_{50}=118{\pm}0.43{\mu}g/mL$, respectively. PCE reduced melanin contents of B16 melanoma cells in a dose-dependant manner and decreased to about 23 % at a concentration of $20{\mu}g/mL$ without cell cytotoxicity (below $100{\mu}g/mL$). And the PCE reduced intracellular tyrosinase activity about 18 % at concentration of $50{\mu}g/mL$. We purified one active compound from PCE and identified its structure. It was identified as patchouli alcohol, sesquiterpene family, by 1H-NMR, $13_C$-NMR, and Mass analysis. Patchouli alcohol also inhibited ROS scavenging activities in DPPH radical and xanthine/xanthine oxidase system with the $IC_{50}$ values of $3.14{\pm}0.12{\mu}g/mL$ and $49{\pm}3.24{\mu}g/mL$, respectively. Patchouli alcohol inhibited melanin synthesis in a dose dependent manner ($IC_{50}=3.9{\mu}g/mL$). And the patchouli alcohol reduced intracellular tyrosinase activity about 40 % at concentration of $10{\mu}g/mL$. Patchouli alcohol inhibited tyrosinase and TRP-2 expression at protein level. These results suggest that PCE and patchouli alcohol reduced melanin formation by the inhibited of tyrosinase activity and expression in B16 melanoma cells. Therefore, we suggest that PCE could be used as a useful whitening agent.

Patchouli oil extraction in general is still using conventional methods that require a long time of extraction. It is therefore necessary to develop extraction methods to obtain patchouli oil with optimum yield and quality. One of the new methods, which has been successfully developed, is microwave hydrodistillation (MHD). In addition to optimizing the extraction process of patchouli oil, this study also used microwave air-hydrodistillation (MAHD). Based on the research results, extraction using MAHD method can produce higher yield of patchouli oil when compared using MHD method. Also, based on the results of the analysis by GC-MS, extraction using MAHD method can produce quality of patchouli oil that is almost the same when compared using MHD method. This is supported by the results of the analysis by GC-MS, which showed that the content of patchouli alcohol is the main component of patchouli oil, and is almost the same for patchouli oil extracted using MHD method (26.32%) and MAHD method (25.23%).
