“…Bergenia has many bioactive compounds in its rhizomes, including paashaanolactone (Chandrareddy et al, 1998), arbutin (Pop et al, 2009), bergenin , catechin and gallic acid Sinha et al (2001a) showed that it had a wide spectrum of concentrationdependent antibacterial activity, in addition, it was demonstrated anti-inflammatory potentiality as described by Sinha et al (2001b). In fact, the whole plant of Bergenia can be used in medicine, but its active ingredients were mainly focused on polyphenols, among which bergenin is studied and applied most frequently (Reddy et al, 1999;Chauhan et al, 2000;Ji, 2005;Singh et al, 2007;Dhalwal et al, 2008).…”

Bergenia, a genus belonging to Saxifragaceae family, is one of the most important medicinal plants, has high application values for human. Currently, wild Bergenia is becoming lacking, due to destruction of ecological environment and excessive excavation; furthermore, the study on it is not deep enough, many related important problems have not been resolved. To protect and utilize more effectively the elite germplasm resource, this study introduced its germplasm situation and reviewed its application values in medicine, horticulture, food and cosmetic and summarized its research advances in biochemistry, cytology and molecular biology. This review can provide an important reference for further study in Bergenia.

“…Because the experimental conditions, preparation methods and standards for the evaluation of photocatalytic activity are there are many argumentative results reported. Some research groups have reported that the presence of these foreign metal species in TiO 2 is generally detrimental for the degradation of organic compounds in aqueous systems (Paola et al, 2000;Navio et al, 1999;Dohshi et al, 2003;Sinha et al, 2001) while some controversial results have also been reported (Choi et al, 1994;Zhang et al, 1998;Yamashita et al, 2002;Araña et al, 2002). The photocatalytic sterilization property of Titanium dioxide (TiO 2 ) has been documented (Watanabe et al, 1999).…”

“…The photocatalytic sterilization property of Titanium dioxide (TiO 2 ) has been documented (Watanabe et al, 1999). The first research on the microbiocidal effect of TiO 2 photocatalytic reactions was carried out with Escherichia coli (Matsunaga et al, 1985) and subsequently has been intensively conducted on a wide spectrum of organisms including viruses, bacteria, fungi, algae and cancer cells (Sinha et al, 2001) In the last decade, TiO 2 has been widely utilized as a selfcleaning and self-sterilizing material for coating many clinical tools including sanitary ware, food tableware and cooking ware and items for use in hospitals (Fujishima et al, 2000). It has been approved by the American Food and Drug Administration (FDA) for use in human food, drugs and cosmetics and compounded in food contact materials such as cutting board and other surfaces in contact with unprotected food.…”

Problem statement: Since bacteria mainly causes damage on fresh vegetables and fruits during transportation to market, anti-bacterial TiO 2 photocatalyst was applied for their packaging films. However, it has been known that pure TiO 2 exhibits low photocatalytic property due to rapid recombination of photo-activated electrons and holes. Doping with metal or metal oxide shows the improvement of photocatalytic activity and disinfection effect. Approach: Fe 3+ was considered to dope into TiO 2 /3SnO 2 photocatalyst in order to enhance the photocatalytic property and bacterial inactivation efficiency. The Fe 3+ doped TiO 2 /3SnO 2 nanoparticles were prepared by sol-gel method and calcined at 400 °C for 2 h. The synthesized powders were characterized by XRD, BET and SEM. Photocatalytic activity and bacteria killing effect were determined by means of degradation of methylene blue solution and inactivation of E. coli bacteria, respectively. These tests were performed under UV and visible light irradiations. Results: Fe 3+ doping into TiO 2 /3SnO 2 has an effect on inhibition of anatase crystal growth, led to the enlargement of the composite specific surface area. Therefore, the photocatalytic activity of Fe 3+ doped TiO 2 /3SnO 2 composite in proper concentration was greater than those of pure TiO 2 and TiO 2 /3SnO 2 and 0.5 mol% Fe 3+ doping exhibited the highest photocatalytic activity and E.coli inactivation efficiency. The E. coli was completely killed within 90 min under UV irradiation or 99.7% inactivated under visible light exposure. Conclusion: Fe 3+ doped TiO 2 /3SnO 2 nanoparticles were successfully synthesized and identified as 100% anatase phase. The 0.5mol% Fe 3+ -doped TiO 2 /3SnO 2 which has particle size of 12.89 µm and specific surface area of 117.61 m 2 g −1 , exhibited the highest activity and disinfection efficiency. An attractive feature of Fe 3+ doped TiO 2 /3SnO 2 photocatalytic disinfection is its potential to be activated by visible light. Therefore, these composite TiO 2 nanoparticles can be utilized for fresh food packaging films.
