The following is a list of morphologic and genetic characteristics of Pinellia tuber. 1. The original plant of Pinellia tuber is Pinellia ternata$(T_{HUNB})$$B_{REIT}$. With regards to its external morphology, it is smaller than other Araceae species and its spadix is longer than its leaves, which trifurcate. 2. As regards its internal morphology, its mucous cell is elliptical and the vessel is helical or annular-shaped. Granules exist in abundance and in various shapes. 3. Distribution and size of laticifers are the key criteria on which to differentiate between domestic and imported Pinellia tuber. Laticifers are mainly distributed in the epidermis in domestic Pinellia tuber and in the cortical parenchyma in imported Pinellia tuber. The size of laticifers is somewhere between 1,3 and $8{\mu}m$ in diameter in imported Pinellia tuber bigger than its domestic counterpart. 4. RAPD markers display a great similarity in bands between domestic and Chinese Pinellia tuber. However, RAPD primers 352, 358, 365, 368 and 374 are distinctive markers for domestic Pinellia tuber. In the meantime, North Korean Pinellia tuber, morphologically similar to domestic Pinellia tuber, is genertically distinctive from its domestic counterpart in primers 354, 358, 365, 368, 374 and 379, a finding that supports the postulation that North Korean Pinellia tuber is tuber of another Araceae species.

Objectives : The purpose of this study was to clarify the daily dose and uses of Goju-tang in Treatise on Cold Damage Diseases. Methods : We compared major editions of Treatise on Cold Damage Diseases with the original text of Supplement to the Essential Prescriptions Worth a Thousand Gold and chose the most appropriate text. If none of the existing texts seemed reasonable, We compared texts item by item. When there is nothing adequate even item by item, it was newly modified. These results were compared with currently distributed Pinellia Tuber and standards of eggs. Results : Goju-tang consisted of Goju(vinegar), Pinellia Tuber and an eggshell. Generally, a daily dose was extracted at once and taken 3 times a day, but in Goju-tang, 4 pieces of Pinellia Tuber and one-third Sheong of Goju(solvent) were used, which were one third of average volume. Pinellia Tuber was used cut in small pieces. And it was boiled gradually by low heat. Goju was mainly to reduce the pungency of Pinellia Tuber by cutting raphides of calcium oxalate. The Pot preparing medicines was eggshell which was chosen by its small size, because the volume of Pinellia Tuber and Goju was one-third of average volume. Since an egg shell is consisted of protein, it didn't react with vinegar(Goju). Conclusions : The 4 pieces of Pinellia Tuber and one-third Sheong of Goju(Vinegar) in the Goju-tang were one-third of average dose, and the eggshell was Pot preparing medicines.

The tuber of Pinellia ternata Breitenbach(Araceae), which is distributed in Korea, China, and Japan, has been used in traditional Chinese medicine. The prescription containing Pinellia tuber shows anti-emetic, sedative, and anti-tussive effects. The purpose of this study was to investigate the effects of Pinellia ternata tuber on the xylazine-induced emetic and sedative responses in cats. The results were as follows ; 1. Intramuscular injection of xylazine hydrochloride(1.0mg/kg) reliably evoked vomiting with an incidence of 100% and sedated with a mean sedation time of 34.22 min. 2. The xylazine-induced emetic and sedative responses were not prevented by oral administration of powder (0.5g/head), decoction ($1.0m{\ell}/100g$), and methanol extract ($0.1m{\ell}/100g$) of the Pinellia ternata tuber. 3. The xylazine-induced emetic and sedative responses were inhibited by intravenous injection of decoction($0.3m{\ell}/100g$) of the Pinellia ternata tuber. 4. The xylazine-induced emetic and sedative responses were inhibited by intravenous injection of a combined mixture of yohimbine hydrochloride(0.125mg/kg) and 4-aminopyride(0.3mg/kg).

The plant growth and yield of Pinellia ternata (Thunb.) Breit. were studied by altitude and tuber weight. The emergence rates in low land area were not different by tuber weights, but it showed earlier emergence date in heavier weight of seed-tuber and low land area. The higher aerial growth such as plant height and number of leaves per plant was the heavier tuber weight in a planting year, but the growth was not different by the weight of tuber at second year after planting. The distribution pattern of tuber size per $m^2$ was not influenced by different seed-tuber weight. The number of harvested tuber was highest at more than 1 g of tuber weight, and followed 1~2 g and less than 2 g. The distribution pattern of fresh tuber yield was not influenced by different altitude and seed-tuber weight. The marketable tuber, 2 g or more, tends to be produced with more than 0.6 g seed-tuber. As the results above-mentioned, it was thought that the high yield was supposed to use seed-tuber over 0.6 g in the fertile soil.

Objectives : The purpose of this study is to report that applying the genetic discrimination method to Pinelliae Tuber is suitable as a countermeasure for the limitations of morphological identification announced publicly in the Ministry of Food and Drug Safety(MFDS). Methods : Randomly selected fifty samples in Pinelliae Tuber imported from China were used for morphological and genetic identification. The morphological identification was applied method announced publicly by the MFDS. The traits of morphological identification were classified as Pinellia ternata, P. tripartita, Pinellia pedatisecta, and Typhonium flagelliforme, according to the formation of tuberous root and tuber morphology. The genetic identifications were conducted by Sequence Characterized Amplified Region(SCAR) marker and DNA barcoding analysis for cross-validation, respectively. SCAR marker was verified according to the presence or absence of amplicon through PCR amplification using species-specific primers. DNA barcoding analysis used sequence information of the matK region. Results : As a result of the morphological identification, 27 out of 50 samples were identified as original species 'P. ternata' of genuine 'Pinelliae Tuber', and 23 were identified as adulterant species 'P. pedatisecta'. Unlike this, the genetic identification was identified as the original species 'P. ternata' in all 50 samples in the SCAR marker and matK regional sequence analysis. Conclusions : Pinelliae Tuber of morphological mutant that can not be classified by morphological identification is imported from China. The SCAR marker would be used as accurate and efficient assays for species identification of the morphological mutant.

Objectives : Pinelliae Tuber has been used as a typical unauthentic herbal medicines. Due to the morphological similarity between Pinelliae Tuber and adulterants, the correct authentication is very difficult. Therefore, we introduced DNA barcode to establish a powerful tool for the authentication of Pinelliae Tuner from adulterants. Methods : To obtain DNA barcode regions, genomic DNA was extracted from nineteen specimens of Pinellia ternata, Pinellia pedatisecta, Pinellia tripartita, and Typhonium flagelliforme, and matK and rbcL genes were amplified. For identification of species specific sequences and analysis phylogenetic relationship, a comparative analysis were performed by the ClastalW and UPGMA based on entire sequences of matK and rbcL genes, respectively. Results : In comparison of two DNA barcode sequences, we elucidated the phylogenetic relationship showing distinct four groups depending on species and identified 40 and 20 species specific nucleotides enough to distinguish each species from matK and rbcL gene, respectively. The sequence differences at the corresponding positions were avaliable genetic marker nulceotides to discriminate the correct species among analyzed four species. These results indicated that phylogentic and comparative analysis of matK and rbcL genes are useful genetic markers to authenticate Pinelliae Tubers. Conclusions : The marker nucleotides enough to distinguish P. ternata, P. tripatrita, P. peditisecta, and T. flagelliform, were observed at 40 positions in matK gene and 20 positions in rbcL gene sequence, respectively. These differences can be used to authenticate Pinelliae Tuber from adulterants as well as discriminate each four species.

The tuber of Pinellia ternata (Thunb.) Brei (TPT) used in traditional Oriental medicine for the treatment of cough, sputum, vomiting, and insomnia, possesses antioxidant, antibacterial, and anti-inflammatory effects. Although recent studies have reported the anticancer effects of TPT in several cancer cells, it is still unclear whether TPT regulates tumor-associated macrophage (TAM) characterized by the immunosuppressive M2 macrophage phenotype. Our results showed that the ethanol extract of TPT (ETPT) suppressed the migration of RAW264.7 mouse macrophage cells and THP-1 human monocytes differentiated into macrophages towards the conditioned media (CM) collected from lung cancer cells, suggesting that ETPT would attenuate the recruitment of macrophages into tumors. In addition, ETPT suppressed the interleukin (IL)-4 or IL-6-induced M2 macrophage polarization in RAW264.7 cells. ETPT treatment not only downregulated the mRNA expression of M2 macrophage markers including arginase-1, mannose receptor C type 1 (MRC-1), and IL-10, but also inhibited the phosphorylation of signal transducer and activator of transcription 3 (STAT3) and STAT6, general regulators of M2 macrophage polarization. Finally, the transwell assay results showed that the CM from M2-polarized RAW264.7 cells increased the migration of mouse lewis lung carcinoma (LLC) cells, while those from RAW264.7 cells co-treated with ETPT and IL-6 significantly reduced the migration of LLC cells. Taken together, our observations clearly demonstrate that ETPT suppressed the cancer cell migration by regulating macrophage recruitment and M2 macrophage polarization.

반하(Pinellia ternata Breitenbach)는 천남성과(Araceae)의 약용 식물로 동아시아 일대가 원산지이며, 유럽과 북아메리카 일부 지역에도 널리 분포하고 있는 식물이다. 반하의 괴경(tuber)은 약재로 사용되어 구토, 염증, 외상을 치료하는 목적으로 사용되고 있다. 보고된 약리학적 작용으로는 항경련, 항종양, 살충, 세포독성 등이 있는 것으로 알려져 있다. 반하는 약리학적으로 유용한 약용식물로 잘 알려져 있음에도 불구하고, 원산지를 판별할 수 있는 신뢰성이 있고 표준화된 방법이 없는 실정이다. 이를 위한 한국산과 중국산 반하를 판별할 수 있는 유의적인 화합물을 탐색하기 위해 UPLC-PDA와 QTof-MS에 기반을 둔 대사체 표지법을 이용하였다. 한국산으로부터 원산지 판별 화합물로 예상되는 화합물을 반복적인 역상 칼럼크로마토그래피에 기반을 둔 활성유도 분획법을 통해 분리하였다. 그리고, NMR과 MS를 포함한 물리화학적, 분광학적 정보의 결과를 토대로 [6]-gingerol이라는 화합물의 구조를 동정하였다. [6]-gingerol은 원산지를 판별할 수 있는 능력과 melanin 생합성 저해 활성을 지닌 기능성 화장품 소재로서 가치가 있다고 판단되어짐에 따라 유효성분 원산지 판별 화합물로 Fingerprint법에 의해 선정되었다. 더욱이, 한국산과 중국산 반하 유래 [6]-gingerol의 함량 비교를 위해, 유효성이 검증된 분석법을 이용하여 이에 대한 검량곡선을 작성하여 그 함량을 비교하였다. 이것은 한국산 반하판별을 위한 화합물 선정과 성공적인 유효성 검증을 다룬 최초의 보고이다.
