Crataegi folium have been used as medicinal and food materials worldwide due to its pharmacological activities. Although the leaves of Crataegus songorica (CS), Crataegus altaica (CA) and Crataegus kansuensis (CK) have rich resources in Xinjiang, China, they can not provide insights into edible and medicinal aspects. Few reports are available on the qualitative and quantitative analysis of flavonoids compounds of their leaves. Therefore, it is necessary to develop efficient methods to determine qualitative and quantitative flavonoids compounds in leaves of CS, CA and CK. In the study, 28 unique compounds were identified in CS versus CK by qualitative analysis. The validated quantitative method was employed to determine the content of eight flavonoids of the leaves of CS, CA and CK within 6 min. The total content of eight flavonoids was 7.8–15.1 mg/g, 0.1–9.1 mg/g and 4.8–10.7 mg/g in the leaves of CS, CA and CK respectively. Besides, the best harvesting periods of the three species were from 17th to 26th September for CS, from 30th September to 15th October for CA and CK. The validated and time-saving method was successfully implemented for the analysis of the content of eight flavonoids compounds in CS, CA and CK for the first time.

Fire Location

Fire is one of the major hazards in coal mines. After the fire broke out.the primary task of disaster rescue is to judge the location of fire and it is the prerequisite of analyzing the combustion state, the base of fire prediction. In this paper, the method of tunnel fire location judgment combining with qualitative and quantitative analysis is used, it includes the qualitative analysis basing on sets theory and quantitative analysis on fuzzy clustering. The potential location can be conversely reasoned by the warning sensors and the scope can be narrowed down widely. On this basis, the distance and similarity between the veritable time difference and the numerical simulation difference are calculated and by the value we can know the site of the fire.

The aim of this paper is to determine the opinions of deaf workers on their labor capacity and the opinions of their hearing co-workers about the labor capacities of the deaf. The sample consisted of 247 respondents, of whom 127 were deaf and 120 were hearing workers. Qualitative and quantitative analysis were used in processing the results. Testing was performed by Wilks' Lambda, tested significance in discriminant analysis was done by F test, at the statistical significance of 0.01. It was found that the sub-sample of respondents had a statistically significant difference in views on claims regarding the exploitation of deaf workers by employers, the employment of deaf people in low-paid simple occupations, and the equally successful but insignificant productivity of deaf workers. The statistical differences found indicate that there are differences in the assessment of the labor capacity of deaf workers in the hearing work environment. Qualitative analysis found that hearing impairment and the subjective attitudes of colleagues without hearing impairment have the greatest impact on the assessment of the labor capacity of deaf workers.

AbstractTartrazine is a synthetic dye that produces a lemon yellow color, and is often added to food or drinks. The addition of tartrazine in food and beverages aims to provide color, so it looks more attractive. The purpose of this research was to analyze content of tartrazine and determine concentration of tartrazine in hard candy. The method used in this research is qualitative and quantitative analysis. Qualitative analysis was carried out by color reaction using FeSO4 30% reagent solution. Quantitative analysis was carried out using UV-Vis spectrophotometry us a wavelength of 429 nm. The results showed that of the ten positive samples contained tartrazine. The concentration of tartrazine in the samples studied were sample A is 196.65 mg/kg, sample B is 75.57 mg/kg, sample C is 283.50 mg/kg, sample D is 89.83 mg/kg, sample E is 356.24 mg/kg, sample F is 73.80 mg/kg, sample G is 3.27 mg/kg, sample H is 308.98 mg/kg, sample I is 3.94 mg/kg, and sample J is 37.08 mg/kg. So from this research, it is known that concentration of tartrazine in samples of hard candy A, C, E and H are not safe because the levels exceed the maximum limit of the requirements set out in BPOM Regulation No. 11 of 2019.Keywords: Analysis; Concentration; Tartrazine; Dyes; UV-Vis Spectrophotometry AbstrakTartrazin merupakan zat pewarna sintesis yang menghasilkan warna kuning lemon, serta sering ditambahkan dalam makanan ataupun minuman. Penambahan tartrazin dalam makanan dan minuman bertujuan untuk memberikan warna, sehingga terlihat lebih menarik. Tujuan dari penelitian ini adalah untuk menganalisis kandungan tartrazin dan mengetahui kadar tartrazin dalam hard candy. Metode yang digunakan dalam penelitian ini analisis kualitatif dan kuantitatif. Analisis kualitatif dilakukan dengan reaksi warna menggunakan larutan pereaksi FeSO4 30%. Analisis kuantitatif dilakukan dengan metode spektrofotometri UV-Vis pada panjang gelombang 429 nm. Hasil penelitian menunjukkan bahwa dari ke sepuluh sampel positif mengandung tartrazin. Kadar tartrazin dalam sampel yang diteliti yaitu sampel A sebanyak 196,65 mg/kg, sampel B sebanyak 75,57 mg/kg, sampel C sebanyak 283,50 mg/kg, sampel D sebanyak 89,83 mg/kg, sampel E sebanyak 356,24 mg/kg, sampel F sebanyak 73,80 mg/kg, sampel G sebanyak 3,27 mg/kg, sampel H sebanyak 308,98 mg/kg, sampel I sebanyak 3,94 mg/kg, dan sampel J sebanyak 37,08 mg/kg. Dari penelitian ini diketahui bahwa kadar tartrazin pada sampel permen keras A, C, E dan H tidak aman karena kadarnya melebihi batas maksimum dari persyaratan yang telah ditetapkan pada Peraturan BPOM No.11 Tahun 2019.Kata kunci: Analisis; Kadar; Tartrazin; Zat Pewarna; Spektrofotometri UV-Vis

The aim of this paper is to make a qualitative and quantitative analysis of the results of the project, which was carried out in the framework of research work at the Faculty of Philosophy, University of Niš, in order to monitor the work of students and evaluate the effects of courses in philosophy on the formation and change of student attitudes. Our basic question is whether the newly acquired knowledge of methodology and philosophy of science affect students’ beliefs. If this effect is visible, in what direction and in what intensity does it go? We used the survey as a research method and a comparative and statistical method for data processing. The results we obtained confirmed the assumption, which we wanted to examine, of the significant influence of philosophy courses on the formation of student attitudes. Acquired knowledge of methodology and philosophy of science work to strengthen critical awareness and nondogmatic approach when considering specific problems. The results are in accordance with the theoretical orientation of the whole study of philosophy as well as the specific aims of the courses (presented in syllabuses).

Bioactive Constituent

The compound ent-7β-hydroxy-15-oxo kaur-16-en-18-yl acetat (CT1) is the major constituent and found uniquely in the medicinal plant Croton tonkinensis Gagnep. This compound was also found to have numerous pharmaceutical activities, therefore, it should be considered as a main bioactive constituent of this plant material. However, the Vietnamese Pharmacopoeia IV (2009) postulates the qualitative analysis of this herb by thin layer chromatography (TLC) using standard sample of herbal Crotonis tonkinensis. In this study, we indicate that the material of this herb could be qualitative analysis by TLC and HPLC by using CT1 as a reference compound. The study also develops a method for quantitative analysis of the compound CT1 in the medicinal materials Crotonis tonkinensis by HPLC (column C18; UV detector at 233 nm; solvent acetonitril-water 65:35). The contents of CT1 in some herbal samples collected in northern Vietnam were determined to be 0,507–1,274% in leaves, 0,318–0,461% in green stems and 0,135–0,176% in old stems, indicating that leaves contain highest amount of CT1. The results of this study suggest that the compound CT1 should be used as a reference compound for qualitative and quantitative analysis of the material herb Crotonis tonkinensis in Vietnamese Pharmacopoeia.
