Liriope platyphylla (Liliaceae), a medical plant distributed mainly in China, Taiwan, and Korea, has been used traditionally for the treatment of cough, sputum, asthma, and neurodegenerative diseases. The present study involved the metabolic profiling of this plant and reports spicatoside A accumulation in four different varieties of L. platyphylla (Cheongyangjaerae, Seongsoo, Cheongsim, and Liriope Tuber No. 1) using HPLC and gas chromatography time-of-flight mass spectrometry (GC–TOFMS). A total of 47 metabolites were detected in the different cultivars using GC–TOFMS-based metabolic profiling. The resulting data were subjected to principal component analysis (PCA) for determining the whole experimental variation, and the different cultivars were separated by score plots. Furthermore, hierarchical clustering, Pearson’s correlation, and partial least-squares discriminant analyses (PLS-DA) were subsequently performed to determine significant differences in the various metabolites of the cultivars. The HPLC data revealed that the presence of spicatoside A was detected in all four cultivars, with the amount of spicatoside A varying among them. Among the cultivars, Liriope Tuber No. 1 contained the highest amount of spicatoside A (1.83 ± 0.13 mg/g dry weight), followed by Cheongyangjaerae (1.25 ± 0.01 mg/g dry weight), Cheongsim (1.09 ± 0.04 mg/g dry weight), and Seongsoo (1.01 ± 0.02 mg/g dry weight). The identification of spicatoside A was confirmed by comparing the retention time of the sample with the retention time of the standard. Moreover, the Cheongsim cultivar contained higher levels of phenolic compounds—including vanillic acid, quinic acid, gallic acid, chlorogenic acid, caffeic acid, and benzoic acid—than those of the other two cultivars. On the other hand, the levels of amino acids were higher in the Seongsoo cultivar. Therefore, this study may help breeders produce new varieties with improved nutraceutical and nutritional qualities.

In this study, methanol extract and its organic solvent fractions were prepared from Prunus davidiana (Carriere) Franch. fruit. Antioxidative activities, polyphenolic and flavonoid contents, and tyrosinase inhibitory activities were evaluated. Among the fractions, ethyl acetate fraction showed the highest antioxidative activity with IC50 values of 5.8 μg/mL and 88.1 μg/mL for DPPH radical and nitrite scavenging, respectively, which were comparable to those of ascorbic acid. Further, total flavonoid and polyphenolic contents were highest in the ethyl acetate fraction with IC50 values of 244.5 mg/g and 210.2 mg/g, respectively. IC50 values for tyrosinase inhibitory activity were 0.310 mg/mL and 0.329 mg/mL for the ethyl acetate and n-butanol fractions, respectively. Based on these results, it is suggested that the ethyl acetate fraction of Prunus davidiana (Carriere) Franch. fruit could be used as a functional material in the food and pharmaceutical industries.

This study was performed in order to determine the effect of roasting (160℃ for 0, 30, 60, 90 min) on the physicochemical characteristics and antioxidant activity of hot water extracts of dried Liriope platyphylla. With respect to Hunter's color value, lightness and yellowness decreased roasting time increased. The difference (ΔE value) in lightness, redness and yellowness was 15.88 and 22.94 for 30 and 60 min. The 30 min roasted sample contained more soluble solid content (12.7 °Brix) than other samples. The pH and acidity of the 60 min roasted sample were 5.06 and 0.14%, respectively. The highest contents in reducing sugar and total phenolic compounds contents was obserned in the 60 min roasted sample (17.68, and 35.01 g/100 g, respectively), and flavonoid content was the highest in the 90 min roasted sample (10.53 mg/100 g). The crude saponin content of the 90 min roasted sample (21.90 mg/100 g) was higher than that of others samples (8.0-15.36 mg/100 g). Moreover, ginsenosides such as Re, Rg3, and Rh2, were detected, among which the Rh2 content was the highest. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity (31.64-53.72%), 2,2'-azinobis(3-ethylbenzothiazoline)-6-sulfonic acid (ABTS) radical scavenging activity (61.59-96.71%), and the ferric reducing antioxidant power (72.38-183.11%) were higher in the roasted samples than in the control group. As a result, we confirmed that roasting increased the amount of active compounds, which increased the yield of useful extract.
