DETERMINATION OF PHYTOCHEMICALS, ANTIOXIDANT ACTIVITY AND BIOCHEMICAL COMPOSITION OF CHINESE MUGWORT (ARTEMISIA ARGYI L.) LEAF EXTRACT FROM NORTHEAST CHINA

Objective: The purpose of this research was to determine antioxidant activity of green tea leaf extract, the value of sun protection factor (SPF),physical properties, and stability of green tea cream.Methods: Green tea leaf extract was obtained by maceration using 96% ethanol. Cream was prepared in three formulas with various concentrationof the green tea leaves extract. The physical evaluations included organoleptic, pH, viscosity, adhesion, spreadability, and stability tests weredone. The determination of the SPF value is calculated using the Mansur equation. Extract of green tea leaf has strong antioxidant activity(IC50 2.19 μg/ml).Results: The green tea leaf extract showed high antioxidant activity (2.19 μg/m). All formulas are organoleptically creamy brownish-green to brown,with a distinctive green tea odor and homogeneous. All formulas met the requirements of physical properties of cream. The creams showed significantchange while they were stored at 4°C and at 40±2°C, but showed no difference when they were stored ad 26°C. SPF values of cream are 0.54; 2.03,and 2.41, respectively.Conclusions: It is clearly indicated that the sunscreen cream of green tea leaf extract is potential to be further developed as cosmetic preparations.

Morinda citrifolia. L leaf is a plant that has the potential as an antioxidant due to the presence of compounds in the form of flavonoids and other phenolic compounds that can function as natural antioxidants. In connection with this, research was carried out to Morinda citrifolia. L formulate leaf extract in the form of effervescent granules. Morinda citrifolia leaf extract was macerated with ethanol 96% as solvent. Phytochemical screening showsthat the extract contains flavonoids, tannins, saponins and alkaloids. The extract was formulated with various concentrations of F1 (20%), F2 (25%), F3 (4%). Determination of antioxidant activity using the DPPH free radical immersion method. The results showed that the concentration in the granules influenced antioxidant activity with IC50 values of 109.05 ppm, 101.33 ppm and 73.28 ppm, respectively

Research has been conducted on the treatment of phlegm cough with miana leaf extract in vitro (effective dose of miana leaf extract as an expectorant and antibacterial agent causing cough with phlegm). The study aims to compare the antioxidant activity of miana leaves from 3 locations where it grows, determine the types of contaminant bacteria in the sputum of cough sufferers, determine the minimum value of inhibitor concentration (MIC) and MKC of miana leaves against the test bacteria causing cough with phlegm, determine the effective dose of miana leaves that can used as a reference for coughing up phlegm and proving the potential of miana leaves as a sputum thinner. Miana leaf extraction is done by the juicer method. Antioxidant activity testing uses the DPPH method. Determination of test bacteria is done by isolating and identifying contaminant bacteria in the sputum sample of cough with phlegm. Testing the effectiveness of miana leaves against test bacteria is determined by the liquid dilution method. Expectorant activity testing was determined by measuring the viscosity of mucus viscosity of cow intestine treated with miana leaf extract. The results found that antioxidant activity was influenced by the location where miana leaves grew with an antioxidant potential of IC72 0.072 mg/ml - 0.76 mg/ml. Contaminant bacteria from sputum samples of cough patients are Streptococcus pneumonia, Klebsiella pneumonia, Staphylococcus aureus, Staphylococcus epidermidis and Enterobacter agglomerans. MIC values for contaminant bacteria are 0.1% - 0.75% and MKC values are found between 0.25% - 1.75%. miana leaf extract has the potential as a sputum thinner at a concentration of 0.01% - 0.1%. The recommended dose of miana leaf extract as a cough with phlegm is 1.75% w/v.

AbstractBiancaea sappan (BS) is traditionally used to treat anticonvulsants, anti-inflammatory, antiproliferative, anticoagulant, antiviral, immunostimulant, antioxidant, and antimicrobial treatments. Flavonoids are found in Secang; flavonoids are secondary metabolites that have antioxidant activity. This study aims to identify the flavonoids using TLC and determination of flavonoids content in BS leaves. Initially, The methanol extract of BS was obtained by maceration with ethanol. The qualitative analysis of flavonoid was using TLC and visualization by sprayed with AlCl3. The determination of total flavonoid content is conducted based on the AlCl3 method with total flavonoids expressed in QE (Quercetin equivalent) at the maximum wavelength of 431 nm. The research results showed that BS leaves contain flavonoids and the total flavonoid content of BS leaf extract is 1.0318 mg QE / g extract.Keywords: Caesalpinia sappan; Flavonoid content, Spectrophotometric
