cord-312959-07sn6d9r	Lee, Yun Ha	Evaluation of green tea extract as a safe personal hygiene against viral infections	2018-01-08		.txt	text/plain	5456	268	49	RESULTS: Using the influenza virus A/Puerto Rico/8/34 (H1N1) as a model, we examined the duration of the viral inactivating activity of green tea extract (GTE) under prolonged storage at various temperature conditions. Toward finding a safe and effective hygiene agent against viruses, we evaluated the durability of antiviral effects of green tea extract (GTE) as a powder type and a solution type over extended periods at various temperature conditions using human influenza A/H1N1 virus. The results showed that 0.05% and 0.1% GTE solutions, stored at 4°C and 25°C as long as 56 days, maintained potent viral inactivating activities, completely removing the viral plaque-forming ability of 10 6 PFU of the viruses (Fig. 2a & b) . Based on the previous report that ascorbic acid stabilized green tea catechins [35] , we examined the effects of the addition of common food preservatives such as ascorbic acid, citric acid, and sodium benzoate on the viral inactivating activity of GTE.	./cache/cord-312959-07sn6d9r.txt	./txt/cord-312959-07sn6d9r.txt
