A new method for analysis of lichen triterpenoids was established using high performance liquid chromatography with the combination of a differential refractive index detector(RID) and a photodiode array detector(PDA).It is proved that this method was convenient to detect and identify aromatic and aliphatic lichen substances;it enabled quantitative analysis of substances having no or less absorption of ultraviolet rays such as *** addition,they can be measured in high accuracy compared with the TLC method.

Screening test on anti-oxidation activity using 1,1-diphenyl-2-picrylhydrazyl(DPPH) was performed for 99 ethanol extracts of 85 species of natural thalli of lichens in order to find novel anti-oxidation *** 17 extracts of natural thalli showed high anti-oxidation *** them,the activities of extracts from Hypogymnia vittata,Peltigera aphthosa,Nephromopsis ornata,Pseudevernia furfuracea,Cladonia vulcani and Peltigera elizabethae were *** of Peltigera *** higher activity than those of other *** ethanol extract of *** had been separated into ethyl acetate-soluble and water-soluble *** anti-oxidative spots were found only in the water-soluble fractions by thin-layer *** compound in the lower spot had the same Rf value,UV spectrum,and color as authentic solorinine that was previously found as a unique quaternary ammonium compound from Peltigera *** now report that the hydrophilic lichen substance,solorinine showed a nearly same anti-oxidation activity(EC50=120?mol/Lol/L) as standard antioxidant Trolox(EC50=150?mol/L).

[Background] Medical staff have many occasions to be exposed to anticancer drugs (ACDs) in the process of performing cancer chemotherapy. Although guidelines for the safe handling of ACDs have been published, actual measures against exposure to ACDs differ between hospitals, and no surveillance data regarding the conditions of each hospital in relation to performing chemotherapy in Japan are available. [Methods] To understand current measures against exposure to ACDs and problems related to cancer chemotherapy at outpatient departments, we conducted a questionnaire survey on doctors, pharmacists, and nurses in 10 leading hospitals for cancer chemotherapy in Japan. [Results] Responses were received from all 10 institutions. The hospital pharmacists prepared all ACDs for outpatients in each institution. All hospitals took basic measures against ACD exposure, such as using personal protective equipment and penetration-resistant waste containers. Conditions against exposure to ACDs generally improved between 2012 and 2015, especially in terms of conveyance of ACDs and use of a closed-system drug transfer device. However, no measures linking ACDs with administration routes or injection sites were commonly taken in any of the hospitals in 2015. [Conclusions] Conditions against ACD exposure improved between 2012 and 2015, possibly because new guidelines were issued. To improve measures for ACD exposure in Japan, preparing more appropriate manuals and offering more opportunities to medical staff for continuing education are considered important.
