Abstract

Corn is a well-cultivated food crop that is grown extensively worldwide. The used portion of corn is its seeds, which are rich in oil. The objective of this study is to separate and characterize tocopherol from corn oil in Dompu, Sumbawa by employing spectroscopic techniques such as ultraviolet (UV) spectrophotometry, ultra-performance liquid chromatography (UPLC), nuclear magnetic resonance (NMR), and liquid chromatography-mass spectrometry (LC-MS). Subsequently, the in-vitro antioxidant activity of the tocopherol was assessed. 1 kilogram of dry maize kernels subjected to 70% ethanol extraction yielded 30 grams (35 ml) of corn oil. The purified isolate obtained from the fractionated extract, using radial chromatography, demonstrated the presence of tocopherol. The isolated sample exhibited the presence of beta-tocopherol. Beta-tocopherol's anti-aging properties were assessed by conducting an in-vitro antioxidant activity test utilizing the tyrosinase enzyme. The IC50 value obtained was 83.954±2.849 ppm. The IC50 value indicates that beta-tocopherol possesses significant antioxidant activity, making it suitable for usage as a primary ingredient in cosmetics and pharmaceutical products.

Abstract

Squalene, a natural isoprenoid, plays a critical role in sterol biosynthesis and exhibits various health benefits, including antioxidant, anti-inflammatory, and antitumor properties. Found in sources such as shark liver oil, amaranth, olive oil, and microbial species, its demand has surged across pharmaceutical, cosmetic, and food industries. However, traditional extraction methods, predominantly from shark liver, raise sustainability concerns. This study explores alternative sources and production strategies, focusing on plant-based and microbial synthesis of squalene. Amaranth seeds and olive oil were highlighted as promising renewable sources due to their high squalene content. Advances in synthetic biology and metabolic engineering have enabled microbial platforms, such as genetically modified yeasts and microalgae, to produce pharmaceutical-grade squalene sustainably. Moreover, the development of innovative extraction techniques, such as supercritical CO₂ extraction, enhances yield and purity while minimizing environmental impact. The research further emphasizes squalene’s potential as a precursor for cholesterol, hormones, and vitamins, alongside its role in improving human health through applications in vaccines, cardiovascular protection, and cancer prevention. Future work should prioritize optimizing extraction methods, exploring untapped natural sources, and scaling microbial production to address the growing global demand sustainably.

Abstract

The global market for wet wipes has seen significant growth in the past decade, establishing them as a popular product for personal care and household use. However, their high water and cellulose content makes them vulnerable to contamination by pathogenic microorganisms, which can cause changes in both their physical and chemical properties. This study aims to evaluate the efficacy of six preservative formulations in preventing microbial contamination in wet wipes. The formulas tested included: Formula 1 (F1) with phenoxyethanol and benzalkonium chloride; Formula 2 (F2) with phenoxyethanol, sodium benzoate, and potassium sorbate; Formula 3 (F3) with phenoxyethanol and caprylyl glycol; Formula 4 (F4) with polyaminopropyl biguanide and caprylyl glycol; Formula 5 (F5) with sodium benzoate, potassium sorbate, and cetylpyridinium chloride; and Formula 6 (F6) with propylene glycol and chlorphenesin. A 28-day challenge test was conducted using a multispecies inoculation technique, including bacteria, mould, and yeast. All formulas were initially sterile, as confirmed by sterility testing. The results showed that Formula F1 was the most effective, reducing microbial growth by over 6 log units within 14 days. Formulas F5 and F6 also demonstrated effectiveness, though microbial reduction in these formulas was slower, only reaching >6 log reduction by day 28. Formulas F2, F3, and F4 did not meet the required standards for mould and yeast reduction. These findings support the use of Formula F1 as the most reliable preservative combination, ensuring the safety and quality of wet wipes.

Abstract

Salah satu minyak nabati yang paling terkenal di Indonesia dan banyak negara lainnya adalah minyak jagung. Minyak jagung telah lama dianggap sebagai pilihan utama di antara minyak nabati karena rasanya yang netral, stabilitasnya yang baik, dan manfaat kesehatannya. Dalam hal produksi tahunan, minyak jagung berada di urutan kesepuluh di antara semua minyak nabati dan menyumbang sekitar 2% dari total minyak nabati yang diproduksi di seluruh dunia. Minyak jagung didapatkan melalui proses ekstraksi bubuk biji jagung menggunakan teknik refluks dan sokhletasi dengan berbagai pelarut, termasuk n-heksana, etanol, dan etil asetat, untuk menghasilkan minyak jagung. Selanjutnya, dilakukan analisis kandungan fenolik dan karotenoid dalam minyak jagung. Hasilnya menunjukkan bahwa ekstraksi dengan metode sokhletasi menggunakan pelarut etil asetat menghasilkan kandungan fenolik dan karotenoid tertinggi, yaitu mg/kg dan  mg/g. Sementara itu, metode sokhletasi dengan pelarut N-heksana menghasilkan kandungan fenolik terendah dan metode maserasi dengan pelarut etanol menghasilkan kadar karotenoid terendah. Sehingga, metode sokhletasi dapat digunakan dalam industri produksi minyak jagung untuk menghasilkan minyak jagung dengan kadar fitokimia lebih tinggi.

Abstract

This study investigated the potential of alpha-linolenic acid (ALA) from Sacha Inchi oil as a therapeutic agent for cervical cancer through an in vitro study on HeLa cells. Cervical cancer is one of the most common types of cancer in women, which is often caused by human papillomavirus (HPV) infection. Although chemotherapy therapy is one of the main methods in cancer treatment, this approach often causes side effects and drug resistance. ALA, which is one of the main components of Sacha Inchi oil, is known to have antioxidant and anti-cancer activities. In this study, Sacha Inchi oil was analyzed using liquid chromatography-high resolution mass spectrometry (LC-HRMS) for identification of its active components. Cytotoxic assays were performed using the MTT method on HeLa cells, which showed that ALA significantly inhibited cancer cell viability at low concentrations, with low IC50 values compared to the positive control compound cisplatin. These results suggest that ALA has potential as an effective anti-cancer agent against cervical cancer cells. This study concludes that ALA from Sacha Inchi oil can be a strong candidate in the development of safer and more effective cervical cancer therapy.

Abstract

Sacha inchi oil is a seed-derived oil from the Amazon Rainforest, known for its high nutritional value and bioactive compounds. It contains essential fatty acids such as omega-3 and omega-6, along with tocopherols, polyphenols, carotenoids, and phytosterols, making it beneficial for health applications. Due to its nutritional and therapeutic properties, sacha inchi oil has gained significant attention in the food, cosmetic, and pharmaceutical industries. This study contributed to identify and analyze the bioactive compounds in sacha inchi oil extracted from seeds obtained in Central Java, Indonesia. The extraction process was carried out using a hot pressing method, followed by qualitative phytochemical analysis and LC-HRMS identification. The phytochemical tests confirmed the presence of flavonoids, alkaloids, tannins, phenolics, saponins, steroids, and terpenoids, all of which contribute to antioxidant, anti-inflammatory, anticancer, and antimicrobial properties. However, LC-HRMS analysis did not detect flavonoids, tannins, and saponins, possibly due to their low concentration, matrix effects, or degradation during analysis. These findings highlight sacha inchi oil’s potential in nutraceutical, pharmaceutical, and cosmetic industries. Its bioactive compounds suggest its potential use in functional foods, dietary supplements, and therapeutic applications, particularly in preventing oxidative stress-related diseases. Further research is recommended to optimize extraction techniques, improve compound stability, and evaluate its bioavailability and long-term health benefits. The presence of bioactive compounds indicates that sacha inchi oil can be a valuable functional ingredient for health and medical applications, contributing to sustainable and natural health solutions.

Abstract

Turmeric extracts have many benefits, such as an anti-oxidant, anti-inflammatory, and neuro-protector for dementia. The turmeric extracts can be prepared in the form of a thin layer of coated tablets through a dipping method using the dip coating and Simplex lattice design (SLD) methods. The quality of the thin layers of coated tablets is much related to the formulation in the coating process. This research aims to formulate and optimize the coating composition of HPMC, PEG-400, and dip time. Consequently, the TSLT meets the standard requirements. The core tablets were made by using the wet granulation method with the formulation of turmeric extract, erosol, lactose, gelatin, and aquades. Before the core tablets had been produced, the eligibility of granules was initially evaluated based on the standard requirements. Subsequently, the core tablets that meet the standard requirements were printed and replicated. The coating processes on core tablets were performed by dipping into the coating solution in the various duration of dipping times: 5, 30, and 60 seconds. The coating solution consists of HPMC, PEG-400, glycerine, sunset yellow, and distillate water. Then, produced TSLTs were evaluated based on the hardness, friability, and disintegration time. The best optimization process for the mixture of HPMC and PEG-400 indicates a more positive value of R (R = 0.2024).

Abstract

This study aims to develop an AmineQDs bioconjugation technique to enhance specific cancer cell targeting. AmineQDs were synthesized using a solvothermal method, modified with amine groups, and conjugated with folic acid via 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide- N-hydroxysuccinimide(EDC-NHS) carbodiimide activation. This bioconjugation process aims to improve the selectivity of QDs toward cancer cells, enabling more effective detection and therapy. Characterization results indicated successful bioconjugation, but the fluorescence of QDs was quenched after conjugation, likely due to electronic structure changes or self-quenching. Further evaluation of reaction conditions, including pH and buffer types, is needed to maintain optical stability. With proper optimization, AmineQDs have the potential to serve as highly accurate and efficient nanotechnology-based cancer diagnostic and therapeutic agents.
