The purpose of the present study is to establish a reproducible method to assess the color of moxa floss, discriminate the samples based on chromatic coordinates and explore the relationship between chromatic coordinates and total flavonoid content （TFC）. METHODS： Moxa floss samples of different storage years and production ratios were obtained from a moxa production factory in Henan Province, China. Chromatic coordinates （L＊, a＊ and b＊） were analyzed with an ultraviolet-visible spectrophotometer and the chroma （C＊） and hue angle （h~） values were calculated. TFC was determined by a colorimetric method. Data were analyzed with correlation, principal component analysis （PCA）. RESULTS： Significant differences in the chromatic values and TFC were observed among samples of different storage years and production ratios. Samples of higher production ratio displayed higher chromatic characteristics and lower TFC. Samples of longer storage years contained higher TFC. Preliminary separation of moxa floss production ratio was obtained by means of color feature maps developed using L＊-a＊ or L＊-b＊ as coordinates. PCA allowed the separation of the samples from their storage years and production ratios based on their chromatic characteristics and TFC. CONCLUSION： The use of a colorimetric technique and CIELAB coordinates coupled with chemometrics can be practical and objective for discriminating moxa floss of different storage years and production ratios. The development of color feature maps could be used as a model for classifying the color grading of moxa floss.展开更多

However, its seedlings are rarely seen around human settlements, raising questions on what factorsmight be limiting its recruitment. We examined the pattern of floss release, seed fall post-dispersal and influences of watering frequency on germination ofCeiba pentandraseeds. Evening,overall, was associated with a significantlyhigher rate and quantity of floss release (p= 0.0001) than were mid-day and morning, correlating well with the speed of wind across the day (rh = 0.666,p= 0.001). Mean dispersal quantity differed significantly between the individual sampled trees, in which the highest dispersal was recorded from trees located in relatively open areas and the lowest was recorded in closed stand trees. Seed fall was higher within100 mdistances than seed fall farther away from dispersing trees, depending on the microsites and weather conditions. Germination started on day 5 onwards and only 15.67% of sown seeds germinated. Watering frequency strongly influenced seed germination while local human activities determined fate of dispersed seeds. We conclude that recruitment ofC. pentandraspecies in the study area may have been limited by environmental and human factors operating at various local and spatial scales.展开更多

These participants came from the medical faculties of Chinese Medicine and Western Medicine. These participants were interviewed to determine the demographic characteristics. Non-flossors responded according to their reasons for not flossing. <strong>Results:</strong> A total of 3481 effective data were available for analysis. The floss prevalence was 17.21%, which was lower by 5.72% for students living in rural areas, when compared to students living in urban areas. The largest proportion of non-flossing participants in rural areas answered, “I do not know what a floss is”, while participants in urban answered, “I do not want to use it”. The largest proportion of answered flossing frequency was less than once a month. <strong>Conclusion:</strong> The present study indicates that the prevalence of using floss in medical faculties in Inner Mongolia Medical University was higher, when compared to that in Sichuan province, China, but lower than that in other countries. Although the students use floss, more than one-third of students use floss less than once a month, which is close to “never”. The prevalence in rural areas is lower than those in urban areas. Male not only comprises the total number of prevalence, but also has a frequency greater than that in females. The emphasis on using floss should be improved in medical students.展开更多
