A mixture of polyphenol components was isolated from the fruits of C. annuum L. cv. Cupra, C. annuum L. cv. Orange glory, and C. annuum L. cv. ST4712 (CLST), via 70% methanol extraction followed by column chromatography over silica gel. The polyphenol components of the mixture were analyzed via HPLC-MS/MS and compared with the reported data. Three cinnamic acid derivatives and five flavonoid components in the fruits of the three varieties were identified for the first time in this study. The antioxidant activity and anticancer effect of the polyphenol mixtures of the three fruits were determined. The antioxidant and anticancer activities of CLST were substantially higher than those of C. annuum L. cv. Cupra and C. annuum L. cv. Orange glory. The high activities of CLST were attributed to the much higher concentration of quercetin derivatives in CLST.

ObjectiveThis study was conducted at Hanawon-a government sponsored educational facility for the settlement of North Korean refugees during their initial phase in South Korea-in 2004 to explore their mental health status and traumatic experiences in North Korea and during their escape period.MethodsA survey was conducted in November 2004 with 62 North Korean refugees at Hanawon, and the Trauma Checklist was used to measure their traumatic experiences. To measure their psychological-mental health status, the Personality Assessment Inventory was administered.ResultsIn comparison with the traumatic experiences of the North Korean refugees found in the study conducted in 2001 at Hanawon using the same methods, the current study showed a relatively lower frequency of traumatic experiences among the participants. The Personality Assessment Inventory results revealed that the study participants scored higher than average South Koreans in all clinical scales. Particularly, their mania (62.51) and schizophrenia (61.75) scores were above 60, a clinically meaningful score. In the gender comparison, the males exhibited meaningfully higher levels of alcohol problem, non-support, and warmth scale scores.ConclusionCompared to the 2001 study, the overall traumatic experiences among North Korean refugees participated in this study. But continous support is necessary for their successful adaptation to South Korean Society have declined. The North Korean refugees at Hanawon experienced difficulties maintaining their mental health and the men in particular requested more intensive care and support for this purpose.
