Abstract

Andrographis paniculata (Burm.f.) Ness is one of the native tradisional medicine in Indonesia which contain active flavonoid. It has potential activity as antioxidant, antibacterial, and inflammation. Antioxidant sensitive to light and heat. Flavonoid antioxidant activity could be decline by heat and oxidation. We can find these caution while evaporate the liquid solvent with heating in conventional evaporation to get dry extract. One of the conventional evaporation instrument is Rotary Evaporator. Other evaporation system, lyophillization is alternative to evaporate solvent without heat. This system uses instrument called Freeze Dryer. Present study about antioxidant activity influenced by two different evaporation using IC50 determination in DPPH oxidation proved that evaporation difference could change antioxidant ability. The result shows freeze dryer evaporation result with 17.06% of extract yield and 585.730 µg/mL IC50 value better than rotary evaporator with 24.96% of extract yield and 792.196 µg/mL IC50 value in solvent evaporate ability and antioxidant activity.

Abstract

Disorders of carbohydrate metabolism can lead to diabetes mellitus. Carbohydrates  are metabolized in the gastrointestinal tract  into simple glucose and absorbed into the bloodstream and affected blood glucose levels. The absorption process is catalyzed by α- 1 ,4 - glycoside breaking bond  enzyme , namely α - amylase and α -1 ,6 - glycoside breaking bond  enzyme, namely α – glucosidase. They are found in the intestinal cells. Research had been conducted in an effort to develop an alternative treatment of diabetes mellitus by testing the ability of isolates of andrographolide in inhibiting α-amylase activity and α-glucosidase in vitro. Andrographolide isolates showed fairly good activity in inhibiting α-amylase ( IC50 = 1,.49 mg/mL) and weak in inhibiting α-glucosidase (IC50 = 38,86 mg/mL). Inhibition of α-amylase activity is evidence of one mechanism of andrographolide in reducing carbohydrate metabolism that can affect blood glucose levels and indicates that andrographolide is  a potential alternative medicine in addressing diabetes mellitus .

Abstract

The oxidative stress mechanism in the body involves the balance between increased ROS and decreased antioxidant agents. ROS can damage DNA, proteins, and lipids, leading to pathology and impaired insulin secretion by dysregulation of several genes expression. High concentrations of ROS are often followed by a low activity of antioxidants from endogenous sources. As a result, exogenous antioxidants are required to neutralize ROS. As reported, medicinal plants, which have had various traditional applications, contain large amounts of secondary metabolites, proven to be exogenous antioxidant agents. Jamu, a traditional medicine, also known as an alternative medication, can be widely and easily found in traditional markets. Antidiabetic herbal products are among the most popular of jamu. Antidiabetic mechanism has a strong relationship with antioxidant roles in many biological systems. The aim of this research was to figure out the potential antioxidant activity of antidiabetic herbal products. Eight antidiabetic jamu samples were analyzed for their antioxidant activity by measuring the DPPH radical scavenging activity, phosphomolybdenum antioxidant activity, and FRAP, as well as for their total phenolic and flavonoid contents. Good linearity was a general finding for the quantitative analysis, with an average correlation coefficient of 0.999 for the standards. The highest total flavonoid content found was 8.66 ± 0.11 mgQE/g, and the highest total phenolic content was 22.66 ± 0.15 mgGAE/g. With regard to antioxidant activity, all of the samples demonstrated weak DPPH radical scavenging activity, while phosphomolybdenum antioxidant activity and FRAP were the highest at 48.58 ± 0.45 mgQE/g extract and 226.98 ± 0.19 mgQE/g extract, respectively. These results indicated that the claimed antidiabetic herbal products could be prepared as exogenous antioxidant sources, irrespective of being with or without antioxidant activity, for diabetes treatment.

Abstract

Solvent is a key factor that affects the effectiveness of active compound extraction from plant materials (simplisia). This study aimed to determine the optimal type and concentration of solvent used in the extraction of pepino fruit based on the parameter of antioxidant and tyrosinase inhibition activity, as well as Sun Protection Factor (SPF) value. The extraction was carried out using the maceration method with ethanol or ethyl acetate as the solvent, each at concentrations of 50%, 70%, and 96%, respectively. The antioxidant activity of the extracts was evaluated using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method. The inhibition of tyrosinase and the determination of the SPF value were carried out using in vitro test. The results showed that the ethyl acetate extract was better than that of the ethanol extract in terms of antioxidant activity, tyrosinase inhibition, and SPF value. In the ethyl acetate solvent, a concentration of 96% provided the strongest antioxidant, tyrosinase inhibition activity, and the second highest in SPF test. It can be concluded that the optimal solvent for extracting pepino fruit as promising compound for sunscreen formulation is 96% ethyl acetate.

Abstract

Adulteration in patchouli oil trade is an ancient practice, where additional substances like turpentine oil are added to increase volume and odor. Therefore, this research aimed to determine the composition of patchouli oil, considering variations in growing regions and potential adulteration in the products available in the market. The analysis was carried out using the Gas Chromatography-Mass Spectrormetry (GC-MS) method with a Principal Component Analysis (PCA) chemometric combination for authentication. The sample obtained from Bantul, Kulon Progo, and Purworejo was isolated through steam and water distillation. Subsequently, it was tested in accordance with SNI standard 06-2385-2006 and analyzed using GC-MS. The results were compared to the products on the market and processed using multivariate chemometric, namely PCA with Minitab 19 software. GC-MS analysis showed the presence of various compounds contained in the oil, including alcohol, alpha-guaiene, beta-humulene, seychellene, trans-caryophyllene, neoalloocimene, and beta-patchoulene. The combination of GC-MS and PCA chemometrics was able to distinguish patchouli oil from others and the products available on the market. PCA chemometric analysis showed that the patchouli oil from various growing regions had the same chemical components as essential oil. Furthermore, PCA chemometric analysis of market products also showed similar results but varied significantly from turpentine oil. This showed that the patchouli oil product available on the market did not contain turpentine oil.

Abstract

Nanostructured Lipid Carries NLCs have gained attention in formulation science and nanotechnology due to their biocompatible material and ability to enhance skin penetration. The goal is to create products that can effectively deliver active compounds to desired skin layers with minimal side effects. This review focuses on the use of functionalized NLCs in dermocosmetics, specifically looking at their composition, manufacturing method, characteristics, and role in delivering active compounds. The review obtained articles from databases such as Scopus, Pubmed, and Google Scholar, covering the years 2014-2024. Data search was conducted in May 2024. The search used keywords such as "NLC OR formulation OR dermal OR activity”. By considering factors such as NLC composition, manufacturing method, and impact on compound delivery, researchers aim to optimize NLCs for use in topical preparations. This research contributes to the development of dermocosmetics that can address various skin problems more effectively. The search results from 32 articles gave an overview of the widely used NLC components: solid lipids: glycerol monostearate, compitrol 888 ATO, and tristearin; liquid lipids: myglyol, transcutol, and oleic acid; surfactants: poysorbat 80 and polysorbate 20. The widely used methods were ultrasonication and high pressure homogenization. Frequently performed characterizations include particle size, polydispersity index (PDI), zeta potential, and Entrapment Efficiency (EE). The pharmacological activity of active components loaded into NLCs increased than without NLCs. The active ingredient formulated in NLC can produce better activity compared to the active substance formulated directly in the conventional preparation. The application of nanostructured lipid carrier (NLC) nanoparticles on the skin is very beneficial. These nano systems have shown promising results and more commercial formulations, so it is expected to be done in further research.
