Oriental herbs are reported as having potent functions for preventing many types of diseases. They also appear to have positive effects and potential capabilities for skin care. Among the many oriental herbs that are available, we chose to analyze four medicinal herbs, Korean red ginseng, Artemisia capillaries Thunb, Schizonepeta tenuifolia Briq, and Foeniculum vulgare Mill, because all are popular and considered as favorite medicinal plants in Korea. Extracts of the herbs were obtained by various methods such as using distilled water, ethyl ether, methanol, ethanol, benzene, 1-butanol, and chloroform. Nine phytochemicals were detected in the extracts: maltol, adenosine, b-pinene, menthone, pulegone, limonene, anethole, estragole, and fenchone, which reportedly have multi-functionalities. All phytochemicals were analyzed quantitatively by various chromatographic techniques such as HPLC and gas chromatography-mass (GC-MS) spectrometry. This article also presents the optimum conditions for extracting these 9 targeted phytochemical compounds that were derived from 4 popular oriental herbs, which could be useful for the efficient preparation of each phytochemical.

Several unusual fatty acids including myristic acid (14 : 0) and lauric acid (12 : 0) were investigated in the Iris family and other related plants. Especially the roots of Iris tecorum contained 75.9% myristic acid in total fatty acid contents and that of Iris germanica contained 57% myristic and 15.5% lauric acid (12 : 0) whereas 10.7% lauric acid and 9.5% capric acid (10 : 0) were detected in the roots of iris ensata as compared to the total fatty acid contents. The total fatty acid contents in the seeds of Foeniculi fructus and Torilis japonica was relatively higher 193.3 mg/g dry wt and 128.2 mg/g dry wt, respectively. 64.5% linoleic acid (18 : 2) and 48.9% ${\alpha}-linolenic$ acid (18 : 3) were observed in the seeds and leaves of iris tectorum whereas its lateral roots contained 9.5% caprylic acid (8 : 0) and 8.6% capric acid. The percentage of myristic acid of the total fatty acid in the immature seeds of iris tectorum and Iris germanica was 10.8% and 15.6%, respectively.

Previous studies have been conducted on domestic materials as a single extract. Research on complex mixtures for maximizing plant characteristics by individual extraction and potential interference with effects is insufficient. Therefore, this study confirmed the GC-MSD according to the extraction of essential oils for Agastache rugosa O. Kuntze(AR), Pinus densiflora Sieb. et Zuccarini(PD), Curcuma longa, Curcuma domestica(CC), Zingiber officinale Roscoe(ZR), Foeniculum vulgare Miller(FV), and Citrus medica L. var. sarcodactylis Swingle(CS). The cytotoxicity, antioxidant, and anti-inflammatory properties of the blending oil were confirmed to confirm its potential as a cosmetic material. As a result of analyzing GC-MSD aroma components, the main components were estragole of AR, à-Pinene for PD, Zingiberene for CC and ZR, Anethole from FV, and D-Limonene for CS. At a concentration of 100 uL/mL with no confirmed cytotoxicity, NO production was inhibited by 70.62%, DPPH radical scavenging activity was 64.03%, and ABTS radical scavenging activity was 89.55%. Through this, blended essential oil suggests the possibility of useful application as a raw material with antioxidant and anti-inflammatory effects in the cosmetic and food industries.

Angiotensin converting enzyme(ACE) belongs to the class of zinc protease and plays an important role in the regulation of blood pressure. In this experiment, we investigated the inhibitory activities of ninety four plant extracts on ACE. The extracts were prepared by water and refluxing with 70% and 100% methanol. Among the extracts, two plant extracts such as Cassia tora, Persicaria cochinchinensis Kitagawa showed more than 60% inhibitory activities, and Foeniculum vulgare Gaertner, Scutellaria baicalensis Georgl, Caragana sinica (Buchoz) Rehder, Inula britannica var. chinensis showed $45.2{\sim}49.7%$ inhibitory activities. Twenty eight plant extracts such as Hemerocallis fulva L, Camptotheca acuminata Decne, Inula britannica var. chinensis, Xanthium strumarium, Polygonatum odoratum, Phellodendron amurense Rupr, Coix lachryma-jobi var. mayuen, Prunus ansu, Hibiscus mutabilis L, Thchosanthes kirilowii, Helianthus annuus, Juglans sinensis showed $30.3{\sim}39.7%$ Inhibitory activities. These results suggest that plant extracts which contain high ACE inhibitory activities may be useful as anti-hypertension agents and to the treatment of hypertension.
