Background: Impurities produced from the basic ingredients of making cosmetics, one of which is lead (Pb). Lead is a substance that is harmful and toxic to the human body. Lead can affect the hematopoetic system, nervous system, reproductive system, endocrine system and is carcinogenic. Objective: To determine the presence of lead (Pb) heavy metal contamination in mascara products circulating in the Banjarmasin traditional market. Methods: This study used a descriptive observational method. Testing qualitatively using KI, NaOH, and HCl reagents. Results: The test results obtained from the sample after being reacted with the three reagents showed a positive presence of lead (Pb) heavy metal. With KI solution shows a yellow-black precipitate, with NaOH solution shows a white precipitate and with HCl solution shows a white precipitate. Conclusion: Qualitative tests on mascara cosmetic products taken at different points of sale in the Banjarmasin traditional market using color reagents in KI solution, NaOH solution, and HCl solution, it can be concluded that the qualitative test results show a positive presence of heavy metal lead (Pb). on mascara products.

Sandoricum Koetjape

ABSTRACT The chemicals contained in an extract must be maintained its quality. The aim of this study is to prove both that the ethanol extract of kecapi (Sandoricum koetjape, Merr.) and keluwih (Artocarpus communis) leaves meet the non-specific parameters on the standardization of the extract. The ethanol extract of kecapi and keluwih leaves were extracted using the ultrasonic method. The extract was tested with non-specific parameters including water content, total ash content and metal contamination level. The test results are compared with standard parameter references. Ethanol extract of kecapi leaf have water content of 27.75% ± 1.708, total ash content of 4.856% ± 0.040 and levels of As metal contamination < 0.030 mg/Kg, Hg < 0.002 mg/Kg, Pb < 0.400 mg/Kg, while ethanol extract of keluwih leaf have water content of 23.206 ± 0.091%, total ash content of 9,678 ± 0.306% and levels of heavy metal contamination of As < 0.03 mg/Kg, Hg < 0.006 mg/Kg, Pb < 0.02 mg/Kg. The both extract meet the standard parameters of water content, total ash content and levels heavy metal contamination. Key words: kecapi leaves (Sandoricum koetjape, Merr.), keluwih leaves (Artocarpus communis), non-specific standardization

Biji nangka kurang diminati oleh masyarakat sebagai bahan pangan. Biji nangka memiliki kandungan senyawa flavonoid yang dapat digunakan sebagai pengobatan. Tujuan peneliti adalah untuk mengetahui pengaruh lama fermentasi terhadap kadar flavonoid total pada ekstrak tape biji nangka (Artocarpus heterophylla Lamk.) yang dilakukan dengan alat spektrofotometer UV-Vis. Manfaat dari penelitian untuk menambah wawasan di bidang farmasi khususnya tentang ilmu kimia amami mengenai pengaruh lama fermentasi terhadap kadar flavonoid total pada ekstrak tape biji nangka (Artocarpus heterophylla Lamk.). Metode ekstraksi yang digunakan adalah metode maserasi dengan mengunakan pelarut etanol 96%. Identifikasi kualitatif mengunakan uji Shinoda, uji NaOH 10%, uji H2SO4 (pekat). Hasil uji kualitatif menunjukan sampel positif mengandung flavonoid. Kesimpulan pada hasil penelitian penetapan kadar flavonoid total yang terkandung dalam ekstrak tape biji nangka pada hari ke-0 sebesar 2,9146±0,0245 mgQE/gram ekstrak, pada hari ke-1 sebesar 3,3050±0,0240 mgQE/gram ekstrak, pada hari ke-2 sebesar 3,6829±0,0244 mgQE/gram ekstrak, dan pada hari ke-3 sebesar 4,0488±0,0244 mgQE/gram ekstrak.  Jackfruit seeds are less interest by the community (people) as food.  Jackfruit seeds containing flavonoid compounds where it can be used as a treatment.  The aim of the researchers was to determine the effect of fermentation time on total flavonoid concentration  in jackfruit fermented seed extracts with a UV-Vis spectrophotometer. The benefits of research to add insight in the field of pharmacy especially about chemistry of amami regarding effect of fermentation time on total flavonoid levels in jackfruit seed “tape” extract (Artocarpus heterophylla Lamk.). Extraction method used is the maceration method using 96% ethanol solvent. Qualitative identification using the Shinoda test, 10% NaOH test, and H2SO4 (concentrated) test. Qualitative test results showed a positive sample containing flavonoids. Conclusions on the results of the experiment  are jackfruit seed "tape" extract on day-0 was 2.9146±0.0245  mgQE/gram extract, on day-1 was 3.3050±0.0240 mgQE/gram extract, on day-2 was 3.68293±0.0244 mgQE/gram and on day-3 was 4.0488±0.024 mgQE /gram extract. The longer fermentation, total flavonoid concentration interest.

Line Characteristic

Electron Spin Resonance (ESR) was used for the examination oi dust samples collected from snow in an urban area. On the main doublet ESR line attributed to the signal of paramagnetic metals, a singlet line characteristic for stable free radical centers (FRC) was observed. A negative correlation of significant level between FRC signal intensity and heavy metal (HM) content was established. It was shown that FRC line intensity of dust may be used as a surrogate parameter for the estimation of air pollution by HM.
