  • Ixeris dentata Nakai (Compositae) is a perennial herb which has been used as a folk medicine for treating diabetes and gastroenteric troubles in Korea. Active compounds were isolated from the aerial parts of Ixeris dentata through the bioassay-guided fractionation and isolation method evaluated for inhibition of monoamine oxidase (MAO) in vitro. The compounds were identified as 5,7,3',4'-tetrahydroxyflavone (1) and 5,7,3',4'- tetrahydroxyflavone 7-glucoside (2), based on physical and spectroscopic characteristics. Compounds 1 and 2 showed a selective inhibition of type B MAO (MAO-B) activity, with IC/sub 50/ values of 15.3 μM and 36.4 μM, respectively, but did not inhibit type A MAO (MAO-A) activity.

  • Petasites japonicus (Compositae) is a perennial herb which has been used as treatment of antitussive, expectorant, sedatives, paralysis, diurectics in folk remedies. The pharmacological studies of this natural drug have not yet estabilished. So, we examined anti-lipid peroxidative effects and liver protective effect on $CCl_4$ induced lipid peroxidation and hepatotoxicity in rats. In vivo liver lipid, MeOH Ex. revealed significant increase of anti-lipid peroxidative effects according to concentration dependently. In chemical parameters obtained from serum analysis, MeOH Ex. as a increase of medicine concentration (0.25 g/kg, 0.5 g/kg, 1.0 g/kg), GOT, GPT, AlP decreased. In 0.5 g/kg GPT administered group, there was relative in GOT, AlP. Cholesterol decreased in 1.0 g/kg and 1.0 g/kg administered group, BUN decreased relatively in 1.0 g/kg administered group.

  • Gentiana uchiyamana Nakai is a perennial herb in Gentianaceous plants. From the root of Gentiana uchiyamana Nakai, the bitter secoiridoid glucosides were isolated and identified as gentiopicroside and swertiamarin. A high-performance liquid chromatographic method for quantitative determination of bitter component, i.e. gentiopicroside in the roots of Gentiana scabra and G. uchiyamana Nakai was developed, using a ${\mu}$-Bondapak $C_{18}$ column and methanol-water mobile phases. The content of gentiopicroside was calculated from calibration curve previously prepared using the standard, 3.55% in the roots of Gentiana scabra and 1.58% in Gentiana uchiyamana Nakai.

  • Allium tuberosum Rotter(Liliaceae) is a perennial herb of which leaves are used for food. Leek has been reported to have pharmacological effects including alleviations of abdominal pain, diarrhea, hematemesis, snakebite, and asthma. To investigate the effect of dietary leek supplementation on the drug-metaboizing enzymes, quinone reductase(QR) and arylhydrocarbon hydroxylase(AHH) activities in the liver, stomach, small intestine and lung, and on the plasma testosterone and dihydrosterone hormone levels, mice were fed 2% and 5% leek diets for 8 weeks. Quinone reductase, an anticarcinogenic enzyme, was significantly induced in stomach, small intestine, and lung but slightly lowered in hepatic tissue in the experimental groups compared to control group. Arylhydrocarbon hydroxylase activity, involved in bioactivation of procarcinogens, was significantly decreased in liver and lung. Leek feeding led to the reduction in the plasma level of dihydrotestosterone which is associated with the incidence of prostate cancer. These findings support the potential chemopreventive activity of leek supplementation.

  • Chrysanthemum zawadskii (CZ) is a perennial herb belonging to the Asteraceae family. CZ is used medicinally to treat inflammatory and uterine diseases in Asia. CZ was extracted with 50% ethanol and CZ extract (CZE; at 125, 250, and 500 mg/kg body weight) was administered orally every day for 5 or 6 weeks to investigate the anti-diabetic effects in streptozotocin (STZ)-induced rats and STZ + high-fat diet (HFD)-fed mice. CZE significantly decreased fasting blood glucose levels in STZ- and STZ + HFD-induced diabetic models. In addition, glucose tolerance and insulin tolerance were improved in the STZ + HFD + CZE group by increasing insulin levels and decreasing hemoglobin A1c (HbA1c) levels in serum. Furthermore, CZE supplements decreased components of the serum lipid profile such as triglyceride, total cholesterol, and low-density lipoprotein cholesterol levels. These results suggest that CZE may be a potential candidate for controlling hyperglycemia.

  • Melissa parviflora Benth. is an aromatic perennial herb of Lamiaceae family. It is one of the most influencial plant and used from centuries in Unani system of medicine for the treatment of various malady such as Epilepsy (mirgi), hemiplegia (falij), migraine (shaqeeqa), insomnia (sehar), indigestion (sue hazm) and palpitation (khafqaan) etc. The Persian physician Avicenna endorsed it for heart problems. It has antitubercular, antipyretic, analgesic and stomachic properties, also used to remove bad breath from mouth, strengthen the gums but its main action is as a tranquillizer and nervine relaxant, it is greatly esteemed for its calming properties. Preliminary performed phytochemical analysis revealed that tannin, flavonoid and saponins are the major components of the plant extract. The plants containing saponins or flavonoids exhibit anticonvulsant activity whereas the flavonoids show various biological activities including antioxidant, anti-inflammatory and cytotoxic-antitumor etc. Keeping in view the tremendous medicinal importance of the plant Badranjboya in Unani Medicine, this review provides updated information on its phytochemistry, therapeutic uses and pharmacological properties.

  • Cnidium officinale is a perennial herb belonging to the family Umbelliferae. Its origin is China and is also distributed in Korea and Japan. In 2017, a phenomenon of browning and wilting of leaves was discovered in the cultivation field of the National Institute of Forest Science, Suwon, Korea. The pathogens isolated from plants were consistent with Fusarium solani as a result of morphological examination and molecular phylogenetic analysis. This is the first record of F. solani on C. officinale in Korea.

  • Dracocephalum rupestre Hance is a perennial herb distributed across China, Mongolia, and Korea. This study reports the first complete chloroplast genome sequence of D. rupestre. The plastome is 151,230 bp long and exhibits a typical quadripartite structure comprising a large single-copy region of 82,536 bp, a small single-copy region of 17,408 bp, and a pair of identical inverted repeat regions of 25,643 bp each. It contains 130 genes, comprising 85 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analysis of D. rupestre and related species of Lamiaceae showed that the genus Dracocephalum is a monophyletic group, and D. rupestre is most closely related to D. psammophilum.

  • Polygonatum falcatum is a perennial herb distributed in East Asia. We determined the characteristics of the complete chloroplast genome in P. falcatum for the first time, with a de novo assembly strategy. The chloroplast genome was 154,579bp in length harboring 87 protein coding genes, 38 tRNA genes and eight rRNA genes. It exhibits typical quadripartite structure comprising a large single-copy (LSC) (83,528bp), a small single-copy (SSC) (18,457bp) and a pair of inverted repeats (IRs) (26,297bp). Phylogenetic analysis of 16 chloroplast genomes from Asparagaceae reveals that the genus Polygonatum is a monophyletic group and that P. falcatum is clustered together with the congener, P. odoratum.

  • 대반하[大半夏: Pinellia tripartita(Blume) Schott]는 천남성과에 속하는 다년생 초본식물로써 중국, 일본, 우리나라를 포함한 아시아 전역에 분포하며 꽃과 전초가 아름다워 최근 원예용으로도 많이 이용되고 있으나 체계적인 대량번식 체계가 구축되어 있지 않다. 본 연구에서는 조직배양을 통해 증식된 대반하 기내 식물의 토양조성별 괴경 생육을 조사하여 비교하였다. 기내 증식된 대반하 괴경의 크기에 따라 직경이 1cm 이상인 경우 Type I, 1cm 이하를 Type II로 나누어 6종의 조합상토에 파종하여 괴경의 비대와 생육을 조사하였다. 괴경의 비대와 전초의 생육변화를 확인하기 위하여 초장, 잎 수, 마른 잎 수, 괴경 수, 괴경 크기, 생체중 및 건물중을 8주간 변화를 측정한 결과, Type I와 II 모두 코이어 68.0%, 피트모스 14.7%, 펄라이트 3.0%, 버미큘라이트 7.0% 및 제오라이트 7.0%로 구성된 조합상토 B에서 가장 우수한 생육을 보였다. 특히 Type I은 조합상토 B에서 괴경 크기와 생체중이 각각 45%와 101%를 보였으며, 이는 생육이 가장 좋지 못했던 처리구인 조합상토 E(코이어 14.3%, 피트모스 14.3%, 펄라이트 42.9%, 버미큘라이트 14.3% 및 제오라이트 14.3%)와 약 2배의 차이를 보였다. 이러한 연구결과는 종자번식이 어려운 대반하의 기내 대량증식을 통한 육묘에 있어 안정적인 토양 순화와 대규모 배양묘 생산을 위한 중요한 기초자료로 활용할 수 있을 것으로 사료된다.
