Behavioral Improvements and its Molecular Mechanism of Ilex kudingcha C.J. Tseng on Animal Model of Alzheimer’s Disease

Alzheimer's disease (AD) is a common chronic neurodegenerative disease with well-defined pathophysiological mechanisms. Ilex kudingcha (IK) C.J. Tseng is commonly known as bitter tea or “Khom” tea in Vietnam. The present study was conducted to investigate the anti-dementia effect of IK using olfactory bulbectomized (OBX) mice. OBX mice were daily treated with IK extract (540 mg/kg) or reference drug, tacrine (2.5 mg/kg) 1 week before and continuously for 3 days after the OBX surgery. The object recognition test, modified Y maze test and fear conditioning test were employed to analyze non-spatial short-term, spatial short-term and long-term memories of the mice respectively. Administration of IK extract and tacrine attenuated these OBX-induced cognitive deficits in mice. The effects of IK and tacrine on spatial short-term memory impairment were reversed by scopolamine, a muscarinic receptor antagonist. The amyloid-beta (Aβ) production in adult transgenic Drosophila brain flies was also investigated by using Western blotting with APP-HA antibody. These results indicated that IK extract improves short-term and long-term memory disturbances in OBX mice and that muscarinic receptor may play a role on these actions. In addition, our result also showed that IK extract reduces the expression of amyloid precursor protein (APP) in brain of AD model using Drosophila melanogaster.

Carbonated Hydroxyapatite Containing Propolis as an Antibacterial Agent Candidate against Aggregatibacter actinomycetemcomitans

One of the periodontal pathogenic bacteria that can cause periodontitis and alveolar bone destruction is Aggregatibacter actinomycetemcomitans. An alveolar bone defect can be treated using a bone graft. Carbonated hydroxyapatite (CHA) is an alloplastic graft material. Alloplastic materials do not have vascularization, which will increase the risk of bacterial adhesion. Therefore, adding an antibacterial agent is needed to prevent bacterial adhesion, which will improve periodontal healing. Propolis is a natural ingredient that has broad-spectrum antibacterial activity and does not cause bacterial resistance. This study aimed to assess the antibacterial activity of carbonated hydroxyapatite after being incorporated with propolis against Aggregatibacter actinomycetemcomitans. Carbonated hydroxyapatite was embedded into four different concentrations of propolis solution (2.5%, 5%, 7.5%, and 10%). An antimicrobial assay against Aggregatibacter actinomycetemcomitans was done using the disc diffusion test method. The inhibition zone was measured to determine the antibacterial ability of the specimens. The inhibition zone was found on the carbonated hydroxyapatite incorporated with propolis at all concentrations. Carbonated hydroxyapatite incorporated with 10% propolis showed the largest inhibition zone. Data analysis using the Kruskal–Wallis test showed a significant difference between the groups tested (p <.05). In conclusion, carbonated hydroxyapatite incorporated with propolis has antibacterial activity against Aggregatibacter actinomycetemcomitans

In-vitro and In-vivo Determinations of Sun Protection Factors (SPF) of Skin Lotions Containing Mountain Papaya Fruit and Mangosteen Peel Ethanolic Extract

Indonesia is a high sun exposure country. Exposure to ultraviolet (UV) causes various kinds of skin disorders such as erythema, sunburn, aging, and cancer. Mountain papaya fruit (Vasconcellea pubescens A.DC.) and mangosteen peel (Garcinia mangostana L.) contains metabolite compounds that can protect the skin from sunlight because of its antioxidants activity. The purpose of this study to determine whether the combination of the mountain papaya fruit and mangosteen peel extracts in skin lotion can be used as sun protectors through the in-vitro and in-vivo study. The experiment was done by extracting the mountain papaya fruit and mangosteen peel through the maceration method. The extracts were formulated into skin lotion in three different formulas with the ratio of mountain papaya fruit extract: mangosteen peel extract as follows F1(1:1), F2(1:3), and F3(3:1). In vitro test was done by using UV-VIS spectrophotometry to determine the SPF value and in vivo test was used erythema-induced rats by exotera beam light. The result of in vitro test gained a high enough SPF value for all three formulas F1=23,23; F2=21,70 and F3=28,64 and the result of in vivo test showed that all three formulas did not indicate the existence of erythema value. It can be concluded that three skin lotion formulas containing mountain papaya fruit and mangosteen peel ethanol extract have the effect of sun protection.

Influence of Propylene Glycol Concentrations in Mangostin Pericarp Extract Gels Formulation: Gels Physical Characteristics, Antibacterial Activity Against Staphylococcus aureus, and Functional Antioxidant Activity Based on Radical 2,2-diphenyl-1-picrylhydrazyl Scavenging Activity

Mangostin (Garcinia mangostana L.) fruit pericarp (GMP) extract has been shown to have antimicrobial and antioxidant activities. This study aimed to formulate and evaluate gel formulations of GMP extract using sodium carboxymethylcellulose as a gelling agent and propylene glycol (PG) in varying concentrations (i.e. 0-40%). GMP extract was evaluated for total mangostin content and antioxidant activity based on 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging method. Physical gel characteristics were also examined. All gels had similar pH and spreadability, however, gel with 40% PG produced significantly lower viscosity. Antibacterial activities against S.aureus were shown to be the same among GMP extract gels. The antioxidant activity of all GMP extract gels could be confirmed based on the radical DPPH scavenging method. PG content of 40% significantly reduced the increase of GMP extract gel viscosity after being stored for four weeks at room temperature. Additionally, the lowest syneresis was also shown for GMP extract gel with 40% PG content.

The research aims to analyse the antioxidant, anti-tyrosinase and anti-wrinkle activities from grapefruit (Citrus Maxima L) and strawberry extracts. Samples were extracted by maceration using 96% ethanol and ethyl acetate, subsequently. The Ferric Reducing Antioxidant Power (FRAP) and β-carotene bleaching (BCB) were used to measure the antioxidant activity. The effect of anti-wrinkle was determined by testing the inhibition of elastase and collagenase enzyme, while anti-tyrosinase activity was analysed using mushroom tyrosinase enzyme. The results showed that strawberry extracts in ethanolic (SE) and ethyl acetate (SEA) have antioxidant activity in FRAP (EC50 = 404.39 ± 3.27 µg / mL and 1978.65 ± 37.25 µg/mL) and BCB (IC50 = 292.30 ± 4.69 µg/mL and 671.11 ± 6.74 µg/mL). Whereas the grapefruit peel extracts both in ethanolic (GPE) and ethyl acetate (GPEA) have antioxidant activity in FRAP (EC50 219.47 ± 71.96 µg / ml and 309.44 ± 95.76 µg/ml) and BCB (EC50 245.19 ± 162.47 µg/ml and 567.54 ± 95.31 µg/ml). As positive standards for FRAP antioxidant analysis were quercetin and vitamin C which has IC50 respectively 18.97 ± 4.50 µg/mL and 24.47 ± 1.44 µg/mL. While in BCB analysis, Butylated Hydroxy Toluene (BHT) used as positive standard (IC50 38.68 ± 5.70 µg/mL). The samples of SE, SEA, GPE and GPEA showed tyrosinase inhibitory activity which the IC50 values were respectively 492.68 ± 1.43; 2658 ± 48.08; 3312.5 ± 222.74; 2985.17 ± 122.80 µg/ml. Kojic acid (IC50 111.52 ± 0.42 µg/ml) is used as positive standard in this study. In addition, SE, SEA, GPE and GPEA were able to inhibit elastase and collagenase enzymes, although their activities were still lower than the positive standard used in this study. Elastastinal in concentration 50 µg/mL giving elastase inhibition about 71.71 ± 0.81 µg/mL, while vitamin C in the same concentration showed collagenase inhibition about 66.79 ± 1.23 µg/mL. It can be concluded that the extract of strawberry and grapefruit peel has antioxidant, anti-tyrosinase and anti-wrinkle activity through inhibition of elastase and collagenase enzymes; thus, they can be used as antiaging cosmetic ingredients.

Synergism of Antioxidant Activity Combination of Buas-Buas (Premnaserratifolia Linn.), Meniran (Phyllanthusniruri L.), Secang (Caesalpiniasappan) and Roselle (Hibiscus sabdarifa) Extracts

Buas-buas, meniran, secang, and rosella have biological and pharmacological activities as antioxidants. The combination of the four plants is expected to provide a more potent synergistic effect on antioxidant activity. The purpose of this study was to analyze the total phenol content, total flavonoids, and antioxidant effects before and after combination. The combination of extracts, buas-buas, meniran, secang, and rosella which are used in sequence is (1: 1: 1/2: 1/2), (1: 2: 1/2: 1/2), and (2: 1 : 1/2: 1/2). Plants used in the form of simplicia was extracted by maceration method. Radical capture activity uses DPPH and IC50 values are determined. Determination of total phenol is expressed equivalent to gallic acid. Total flavonoids are expressed as quercetin equivalents. The phenol and flavonoid content obtained are then correlated with antiradical activity. The results showed that the best IC50 values were in the combination of ratios (1: 1: 1/2: 1/2) that is (11.0 µg / mL), then (1: 2: 1/2: 1/2) which was 13.3 µg / mL, and (2: 1: 1/2: 1/2) which is 19.4 µg / mL. The highest total phenolic and flavonoid content in the ratio (1: 2: 1/2: 1/2) is 33.57% w/w EAG and 74.00% w/w EQ. Correlation analysis between IC50 values with total phenolic and flavonoid contents showed a positive correlation with R2 values of 0.8236 and 0.0102 with positive slope. Thus, it can be concluded that the total phenol content influences free radical scavenging activity by 82.36%, while the effect of total flavonoid content was only 1.02%.
