This case report study investigated the botanical, physicochemical, and phenolic compositions, as well as the antioxidant and antimicrobial properties of varying amounts of black cumin honey (Nigella sativa) from Burdur region of Turkiye. The samples had an average moisture value of 17.23% and a Nigella sativa pollen ratio ranging from 19% to 51%. Electrical conductivity (EC) values ranged from 0.36 to 0.54 mS/cm. The average color values of Hunter (L, a, b) were 43.55 (L*), 32.77 (a*), and 64.52 (b*), respectively. The proline contents were ranged from 875 to 1624 mg/kg. The average F/G ratio and F+G value were 1.43 +/- 0.11 and 68.75 +/- 4.75, respectively. The average of total phenolic (TP) and total flavonoid (TF) contents were 36.87 +/- 7.00 mg GAE/100 g and 5.63 +/- 1.45 mg QUE/100 g, respectively. The antioxidant capacities of the samples were tested using the ferric reducing/antioxidant power (FRAP) and 2,2-Diphenyl-1-picrylhydrazyl (DPPH) assays, with mean values of 179.40 +/- 25.35 mu mol FeSO4 center dot 7H(2)O/100 g and 46.07 +/- 12.87 mg/mL, respectively. The phenolic composition of the samples were tested using the HPLC-PDA method with 25 phenolic standards. Gallic acid, p-OH benzoic acid, t-cinnamic acid, p-coumaric acid, chrysin, and pinocembrin were determined as common components. The samples exhibited high antimicrobial activities against Staphylococcus aureus, Escherichia coli, Chromobacterium violaceum, Bacillus cereus, Klebsiella pneumoniae, and Acinetobacter haemolyticus, but did not affect Candida albicans, Candida parapilopsis, or Mycobacterium smegmatis.

世界核心医学期刊文摘（妇产科学分册） 2005年第4期1卷 22-22页

作者： Derman O. kanbur N.O. Tokur T.E. Kutluk T. 张丽娟 Section of Adolescent Medicine Department of Pediatrics Ihsan Dogramaci Childrens Hosp. H. Ankara Turkey

Objective: To investigate the frequency of premenstrual syndrome (PMS) associated symptoms and effects of nutrition on PMS in adolescent girls. Patients and methods: One hundred and seventyone adolescent girls who had menstrual cycles were included in this study. They were given a questionnaire on criteria for PMS, dysmenorrhea and regularity of menstrual cycle. Modified Diagnostic and Statistical Manual of Mental DisordersIV (DSMIV) criteria were used for the diagnosis of PMS. We also investigated which nutritional supplements affect the PMSassociated symptoms and signs. Results: One hundred and five adolescent girls out of 171 (61.4%) met DSMIV criteria for PMS. There was an association between dysmenorrhea and PMS in 60 (57.1%). Half of the girls, i.e. 52 (49.5%) had mild, 39 (37.1%) had moderate and 14 (13.4%) had severe PMS. The most common symptom of PMS was negative affect particularly in the form of stress (87.6%) and nervousness (87.6%). There was a statistically significant negative relationship between milk consumption and the following: abdominal bloating, cramps, craving for some foods and increased appetite. Conclusion: PMS and dysmenorrhea are frequently overlapping. We also found that PMS is associated with dietary habits.
