Perilla frutescens seed (PFS) oil is reported to inhibit skin photoaging;however, its effect on melanogenesis has not yet been investigated. 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

Objective: To investigate the composition of volatile compounds in the different accessions of Perilla frutescens(P. frutescens) collected from various habitats of China and Japan. 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

Influences of PGR, sucrose, and ammonium nitrate on in vitro flowering and fruiting from cotyledon explants of P. frutescens were studied. 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

Perilla frutescens L. is a traditional medicinal plant in china. In recent years, with more and more attention is paid to the nutritional and health values of Perilla frutescens L, it has become a potential medicinal and edible crop. Two Per- ilia frutescens cultivars, Qisu No.1 (oil type) and Qisu No.3 (leaf and seed-using type), bred by Rapeseed Research Institute of Guizhou Academy of Agricultural Sciences, were used as test material for studying the effects of different planting density on the economic yield and agronomic characters of Perilla frutescens L. under moderate fertility level. The results showed the variation tendency of agro- nomic characters with the change of planting density was similar for the two Perilla frutescens cultivars. Among them, the plant height, main-stem nods, first effective branch length, first effective branch height, spikes per plant, and yield per plant were negatively related to the planting density; and main spike length and main- spike grains were positively related to the planting density. The effects of planting density on kilo-grain weight were not significant. The yield of the two cuitivars all increased first and then decreased with the increase of planting density. The re- gression analysis of planting density versus yield of Perilla frutescens L. was per- formed for obtaining the regression equations (Qisu No.l: y=54.046 5+96.777 lx- 45.719 8x2, r=0.999 4; Qisu No.3:y=38.717 6+42.111 3x-16.757 7x2, r=0.999 8). Based on the regression equations, the optimal planting density for Qisu No.1 was 158 745 plants/hm2 with peak yield of 1 578.90 kg/hm2, and for Qisu No.3 was 188 745 plants/hm2 with peak yield of 977.55 kg/hm2. Under the optimal planting density, Qisu No.3 could also harvest 3 000 kg/hm2 of Perilla frutescens dry leaves and 2 400 kg/hm2 of Perilla frutescens stems. This research would provide an important reference for the promotion, high-yield cultivation and comprehensive utilization of Perilla frutescens L. 展开更多

Objective:In this study,we aimed to identify the genes involved in leaf margin serration in Perilla frutescens.P.frutescens(Family:Lamiaceae)is widely grown in Asian countries.Perilla leaf is the medicinal part stipulated in the Chinese Pharmacopoeia.There are mainly two types of perilla leaves:one with serrated leaf margin which is the phenotype described in the pharmacopoeia and the other with smooth leaf margin.Methods:Transcriptome sequencing,co-expression analysis,and qRT-PCR analysis of six perilla tissues sampled from two different phenotypes(serrated and smooth leaves)were performed.Results:Forty-three differentially expressed genes(DEGs),which may potentially regulate leaf shape,were identified through de novo transcriptome sequencing between the two groups.Genes involved in leaf shape regulation were identified.Simultaneously,we validated five DEGs by qRT-PCR,and the results were consistent with the transcriptome data.In addition,1186 transcription factors(TFs)belonging to 45 TF families were identified.Moreover,the co-expression network of DEGs was constructed.Conclusion:The study identified the key genes that control leaf shape by comparing the transcriptomes.Our findings also provide basic data for further exploring P.frutescens,which can help study the mechanism of leaf shape development and molecular breeding. 展开更多
