In this study, we investigated the effect of the essential oil inhalation of Cyperi rhizoma and Perillae herba which were main aromatic herbs ingredient of the Kososan, to psychological condition, autonomic nerve activity and salivary biomarker. In addition, we examined influence by the favorite difference in odor. 25 healthy female volunteers (control group: 5 people;Cyperi rhizoma group: 10 people;Perillae herba group: 10 people) were examined. POMS was examined at PRE and POST the experiment. Pulse analyser was examined and saliva samples were collected before the inhalation, just after the inhalation, 10 minutes and 20 minutes later, respectively. Saliva samples analyzed for levels of α-amylase and cortisol. At the examination for POMS after the experiment, the preference for the odor was confirmed. About both Cyperi rhizoma and Perillae herba, by the essential oil inhalation, mental stability and relaxation effect were provided in psychological and psysiological evaluation. In the “like” group, relaxation was greater than “unlike” group. However, about Cyperi rhizoma, the stress was relaxed regardless of the favorite difference in odor, and a physical relaxation effect was shown. In addition, about the autonomic nerve activity, the parasympathetic nerve was not activated, and it was suggested that it was made and stabilized the balance of the autonomic nerve.展开更多

Herein, we tested the anti-melanogenesis activity of an oil-based extract from PFS with supercritical carbon dioxide (scCO<sub>2</sub>). In a cell culture system, B16 mouse melanoma cells were treated with the PFS scCO<sub>2</sub> extract and other samples. The PFS scCO<sub>2</sub> extract decreased melanin production by approximately 90% in B16 mouse melanoma cells without cytotoxicity at 100 μg/mL. This effect was greater than that of the well-known melanogenesis inhibitor, kojic acid. Although a hexane-extracted PFS oil and a squeezed PFS oil also decreased melanin production in the B16 cells, the inhibitory effect of the PFS scCO<sub>2</sub> extract was higher than both of these. Chemical analysis of the PFS scCO<sub>2</sub> extract and squeezed PFS oil showed that almost 90% of the components of both oils were α-linolenic acid, linoleic acid, and oleic acid. Furthermore, the ratio of those three fatty acids across both samples was almost the same. When the three fatty acids were mixed in the same ratio as in the PFS scCO<sub>2</sub> extract, the IC<sub>50</sub> of the mixture for melanin production in B16 melanoma cells was identical to that of the PFS scCO<sub>2</sub> extract. However, the IC<sub>50</sub> of the squeezed PFS oil was approximately 6.6 times higher than that of the mixture. Although those fatty acids are the main inhibitory ingredients against melanin production in all of the extracts, some factor(s) in the squeezed PFS reduce their affinity with the cells. These results indicated that the PFS scCO<sub>2</sub> extract could be a superior melanogenesis inhibitor. Although its main ingredients are probably the same as those of the squeezed PFS oil, it is necessary to extract with scCO<sub>2</sub> for stronger anti-melanogenesis activity.展开更多

The fatty acid composition was determined after ethyl esterification by gas chromatography (GC). In this process, orthogonal experiment was carried out. Under optimum conditions, the maximum amount of α-linoleic acid (91.5%) was obtained at a urea to fatty acid ratio of 3, a solvent to fatty acids ratio of 7, a reaction temperature of 348 K and a crystallization time of 690 min. A simple method of gradient cooling urea inclusion was used to purify α-linolenic acid by using urea to form inclusion complexes with the saturated and the less unsaturated fatty acids, which enhanced the purity of α-linoleic acid ethyl ester by above 90%.展开更多

The regenerated shoots at 2-4. cm from cotyledon explants on MS medium supplemented with 0.5 mg L^-1 BA and 1.0 mg L^-1IAA were excised and transferred to MS medium containing 30 g L^-1 sucrose, 8.25 g L^-1 ammonium nitrate, and 1.0 mg L^-1 BA. Following 40 d of culture, 86.2% of them flowered and set seeds. These seeds were germinable and developed into flowering plants in the fields. This study provides a simple system for rapid breeding of P. frutescens and studying the physiological mechanism of flowering of plants.展开更多

Methods: In the present study, the essential oil from the leaves of P. frutescens cultivars from China and Japan was extracted by hydro-distillation and the chemical composition and concentration of the volatile components present in the oils were determined by gas chromatography–mass spectrometry(GC–MS) analysis. Results: Among the volatile components, the major proportion was of perilla ketone, which was followed by elemicin and beta-caryophyllene in the Chinese Perilla cultivars. The main component in the oil extracted from the Japanese accessions was myristicin, which was followed by perilla ketone and beta-caryophyllene. We could distinguish seven chemotypes, namely the perilla ketone(PK) type, perilla ketone, myristicin(PM) type, perilla ketone, unknown(PU) type, perilla ketone, beta-caryophyllene, myristicine(PB) type, perilla ketone, myristicin, unknown(PMU) type, perilla ketone, elemicine, myristicin, beta-caryophyllene(PEMB) type, and the perilla ketone, limonene, betacryophyllene, myristicin(L) type. Most of the accessions possessed higher essential oil content before the flowering time than at the flowering stage. The average plant height, leaf length, leaf width of the Chinese accessions was higher than those of the Japanese accessions. Conclusion:The results revealed that the harvest time and geographical origin caused polymorphisms in the essential oil composition and morphological traits in the Perilla accessions originating from China and Japan. Therefore, these chemotypes with desirable characters might be useful for industrial exploitation and for determining the harvest time.展开更多
