Background: Tuberculosis remains a major public health threat. Studies have shown that medium chain fatty acids (MCFA), such as, those found in Virgin Coconut Oil (VCO), possess activity against a wide range of microorganisms including Mycobacterium tuberculosis. The goal of the study was to determine the in-vitro susceptibility of M. tuberculosis (TB) isolates to two commercial brands of VCOs each containing different amounts of lauric acid and produced by two different extraction processes. Two brands of VCO were tested for their anti-TB actions compared to pure lauric acid and a negative control. Two replicate runs were done. VCO samples were inoculated with 0.1 mL of the H37RV strain of M. tuberculosis and incubated at 370C with shaking for 5 days. After incubation, the mixtures were diluted 10-fold up to 10-4 concentration to obtain countable colonies using Middlebrook 7H10 agar plates and Lowenstein-Jensen (L-J) slants. Colony growths of M. tuberculosis were examined in each dilution every week for three to eight weeks. Results: Both brands of VCO at increasing dilution from 1:10 to 1:10000 lowered the colony counts of M. tuberculosis by 46% to 100 % on the Middlebrook 7H10 agar. Similar results were noted on L-J slants with colony counts decreasing by 25% to 96%. Lauric acid solution showed complete inhibition of bacterial growth in both the agar plates and LJ slants. Conclusion: Different VCO preparations containing different amounts of lauric acid exhibited different degree of inhibition against M. tuberculosis. The result of the study suggests the potential of VCOs agent against the growth of M. tuberculosis Similar effect on other organisms is a possibility and should also be explored. But more studies are needed to replicate the studies using different concentrations of VCOs, lauric acid and other fatty acids in VCO such as myristic acid, caproic or caprylic acids.Key words: Lauric acid, virgin coconut oil, tuberculosis, food supplement

Virgin coconut oil has been made by using papaya leaf extract as a source of the papain enzyme. Papaya leaf extraction with maceration used ethanol 95% as solvent. The crude ethanol extract was purified by means of gradient column chromatography using hexane, diethyl ether and ethanol as solvents. The results showed that using papaya leaf extract could significantly increase the quantity of VCO. Coconut milk cream without treatment (negative control) obtained 3.0042 ± 0.046g of VCO, while treatment with papaya leaf extract gained 6,039 ± 0.049 - 7,952 ± 0.031g of VCO, an increase of about 97.5% - 161%. Based on the medium chain saturated fatty acids (MCFA) and long chain saturated fatty acids (LCFA) in VCO, it indicated that the quality of VCO obtained was not good. VCO in diethyl ether fraction and crude extract etanol produced yellow VCO, indicating chlorophyll was still there. Etanol fraction of VCO provided the best quality with the most of lauric acid content and clear color. The VCO components identified using GCMS analysis obtained several fatty acids such as capric acid, lauric acid, myristic acid, palmitic acid, oleic acid, stearic acid, and stearic epoxy.  Keywords: virgin coconut oil, papain enzyme, papaya leaf extract Telah dilakukan pembuatan virgin coconut oil dengan ekstrak daun pepaya sebagai sumber enzim papain. Proses ekstraksi daun pepaya dengan cara maserasi menggunakan pelarut etanol 95%. Ekstrak kasar etanol hasil maserasi dimurnikan dengan cara kromatografi kolom elusi gradient menggunakan pelarut heksana, dietil eter, dan etanol. Hasil penelitian menunjukkan bahwa ekstrak daun pepaya secara signifikan dapat meningkatkan kuantitas VCO. Krim santan tanpa perlakuan (kontrol negatip) didapatkan berat VCO 3.0042±0,046g, sedangkan dengan ekstrak daun pepaya diperoleh berat VCO 6.039±0,049g – 7.952±0,031g, terjadi kenaikan sekitar 97,5% - 161%. Berdasarkan kandungan asam lemak rantai medium dan asam lemak rantai panjang pada VCO, menunjukkan bahwa kualitas VCO yang diperoleh masih kurang baik. Krim santan dengan daun pepaya fraksi dietil eter dan ekstrak kasar etanol menghasilkan  VCO berwarna kuning yang mengindikasikan masih terdapat klorofil. VCO fraksi etanol yang memberikan kualitas paling baik dengan kandungan asam laurat paling banyak dan berwarna bening. Komponen VCO yang teridentifikasi dari analisis GCMS diperoleh beberapa asam lemak seperti: asam kaprat, asam laurat, asam miristat, asam palmitat, asam oleat, asam stearat, dan epoksi stearat. Kata kunci: virgin coconut oil, enzim papain, ekstrak daun pepaya

Breastmilk (ASI) is the best food produced by the breast glands, containing all the nutritional elements needed by infants aged 0-6 months. Apart from nutrients, breast milk also has other non-nutritional components that act as immune factors for babies. Babies who are not exclusively breastfed will be more susceptible to chronic diseases, such as heart disease, hypertension, and diabetes as adults and can suffer from malnutrition and obesity. Dietary intake significantly affects milk production. The mother's diet can affect the composition of her milk through several metabolic pathways, especially the concentration of fatty acids and vitamins that are soluble in fat and water, including vitamins A, C, B6, and B12. Lauric acid contained in breast milk can help your minor fight infection and increase immunity to protect from various diseases. Not only for the baby, but virgin coconut oil is also starting to be commonly used by dieters. Virgin coconut oil contains lauric acid CH3 (CH2) 10COOH 50% and caprylic acid CH3 (CH2) 6COOH 7%. Both of these acids are medium-chain saturated fatty acids that are quickly metabolized and have anti-microbial properties. The benefits of virgin coconut oil (VCO) are that it is beneficial for the health of the body, including being antibacterial, antiviral, anti-fungal, and natural anti-protozoa; helps relieve symptoms and reduces health risks associated with diabetes, helps protect against osteoporosis, helps prevent high blood pressure, helps prevent liver disease, keeps the heart and blood vessels healthy, helps prevent cancer, helps you lose weight, maintain stamina, maintain healthy skin and hair.Keywords: Breastmilk, Lauric Acid, VCO

The nutritional value and biochemical properties of oil are measured by the fatty acids composition  in oil and the position of fatty acids (sn-1,2,3) in the triacylglycerol (TAG) molecule. The purpose of this study was to measure the nutritional value based on the fatty acids composition of  virgin coconut oil (VCO) and palm kernel oil (PKO), and the position of lauric acid in sn-2. The VCO used was VCO obtained from one of the Pharmacies store in Medan, and PKO from the Oil Processing Plant. The total fatty acid composition was measured by Gas Chromatography. The nutritional value of fat was evaluated by the percentage deviation from 33.33% (ratio: 1: 1: 1) of each group of fatty acid (saturated fatty acids; SFA: monounsaturated fatty acids; MUFA:polyunsaturated fatty acid (PUFA). The distribution of lauric acid in TAG was conducted through hydrolysis by using specific lipase enzymes active at sn-1,3 positions, so that free fatty acids and 2-monoacylglycerol were produced from one TAG molecule. Then free fatty acids were determined by Gas Chromatography. The distribution of lauric acid at sn-2 position was the difference between total lauric acid on TAG before hydrolysis and free lauric acid from sn-1.3 position after hydrolysis. The results showed that PKO nutritional value was better because of the smaller deviation (95.29%) compared with nutritional value of VCO with a greater deviation (118.55%). Lauric acid in sn-2 from VCO and PKO showed that the distribution of lauric acid in sn-2 position was not different,48.33and 48.59%.

In 3 experiments, the methane-suppressing effects of medium-chain fatty acids were investigated using basal diets of extensive type (high structural carbohydrate content) and intensive type (low structural carbohydrate content). In Expt 1, sheep were fed the extensive-type diet supplemented with 60 g/kg of rumen-protected fat (control) or coconut oil. The use of coconut oil in the diet did not clearly reduce methane release from the total digestive tract. In 2 in vitro experiments carried out with a RUSITEC apparatus, interactions of either coconut oil (Expt 2) or pure non-esterified lauric acid (Expt 3) with the 2 types of basal diet were determined using 2 × 2 factorial designs. Expt 2 confirmed a high efficacy of coconut oil against methane release in the intensive-type diet (suppression by 62% relative to control) and a reduced efficiency in the extensive-type diet (suppression by 6% relative to control). In contrast, pure lauric acid supplementation suppressed methane release in vitro by approximately 80%, and this was independent of the basal-diet type used. The results suggest that interactions of fat with the basal diet in the rumen have to be taken into consideration to develop effective feeding strategies against ruminal methane formation.

Background: Coconut oil is an edible oil obtained from fresh, mature coconut kernels. Few studies have reported the anticancer role of coconut oil. The fatty acid component of coconut oil directly targets the liver by portal circulation and as chylomicron via lymph. However, the anti-cancer activity of coconut oil against liver cancer cells and oral cancer cells is yet to be tested. The active component of coconut oil, that is responsible for the anticancer activity is not well understood. In this study, three different coconut oils, Virgin Coconut Oil (VCO), Processed Coconut Oil (PCO) and Fractionated Coconut Oil (FCO), were used. Objective: Based on previous studies, it can be hypothesized that fatty acids in coconut oil may have anticancer potential and may trigger cell death in cancer cell lines. Methods: Each cell line was treated with different concentrations of Virgin Coconut Oil (VCO), Processed Coconut Oil (PCO) and Fractionated Coconut Oil (FCO). The treated cells were assayed by MTT after 72 hr of incubation. The fatty acid composition of different coconut oils was analyzed by gas chromatography. Result: Different concentrations of coconut oils were used to treat the cells. Interestingly, the anticancer efficacy of VCO, PCO and FCO was not uniform, rather the efficacy varied from cell line to cell line. Only 20% VCO showed significant anticancer activity in HepG2 cells in comparison to 80% PCO against the KB cell line. Remarkably, 20% of PCO and 5% of FCO showed potential growth inhibition in the KB cell line as compared to 80% PCO in HepG2 cells. Moreover, there was a difference in the efficacy of VCO, PCO and FCO, which might be due to their fatty acid composition. Comparing the anticancer efficacy of VCO, PCO and FCO in this study helped to predict which class of fatty acids and which fatty acid might be associated with the anticancer activity of VCO. Conclusion: This study shows that VCO, PCO and FCO have anticancer efficacy and may be used for the treatment of cancer, especially liver and oral cancer.

The sugarcane aphid, Melanaphis sacchari Zehntner (Hemiptera: Aphididae), is the main pest of sorghum, Sorghum bicolor L. Moench (Poaceae), in Mexico. To control this insect, farmers currently use synthetic chemical insecticides, which are toxic to humans and biodiversity. However, natural products are a promising potential source of safer alternative means to control different agricultural pests. The main objective of this study was to evaluate the insecticidal effect of contact by fumigation of pure molecules of four commercial fatty acids (palmitic, stearic, pentadecanoic and linoleic acids), the phytosterol ß -sitosterol, and the flavonoid rutin. The results showed that fatty acids were the most effective against M. sacchari ; the highest mortality rate (85%) was produced by linoleic acid and the LC 50 was 1,181 ppm, followed by stearic and palmitic acids with mortality percentages of 74 and 63%, respectively, at a concentration of 2,500 ppm at 72 h. The positive control, imidacloprid, had 100% mortality in 24 h and the tween 20 negative control exhibited 4% mortality in 72 h. Our results show that commercial fatty acids are effective against adults of M. sacchari , and can be considered an environmentally friendly alternative to the frequent use of synthetic chemical insecticides.

AIM: The objective of the study was to evaluate protein expression in NIH 3T3 cells that are treated with virgin coconut oil (VCO) and hydrolysed of virgin coconut oil (HVCO) in vitro. METHODS: Coconut oil used in this study was virgin coconut oil (VCO) and VCO hydrolysed by Rhizomucor miehei (HVCO). NIH 3T3 cells (5x105 cells/well) were seeded in nine wells and incubated for overnight, then divided into three groups. Each group consisted of three wells. Group one without treatment, group two added VCO, and group three added HVCO and then incubated for overnight. One well in each group was added MMP-9, PDGF-BB, and TGF-β1 and incubated one hour. Finally, expressions of MMP-9, PDGF-BB, and TGF-β1 were detected using immunocytochemistry method. RESULTS: The results of the study showed that VCO and HVCO increased protein expressions of MMP-9, PDGF-BB, and TGF-β1. Percentage of MMP-9 expressions treated by VCO increased from 2.89 ± 0.07 to 28.16 ± 0.34, PDGF-BB from 28.11 ± 0.13 to 48.53 ± 0.49, and TGF-β1 from 4.19 ± 0.08 to 18.41 ± 0.54. Percentage of MMP-9 expressions treated by HVCO increased from 2.89 ± 0.07 to 55.40 ± 0.94, PDGF-BB from 28.11 ± 0.13 to 61.65 ± 0.42, and TGF-β1 from 4.19 ± 0.08 to 36.35 ± 0.67. CONCLUSION: VCO and HVCO increase the expression of MMP-9, PDGF-BB, dan TGF-β1 in NIH3T3 cells and therefore, coconut oil active in the wound healing process. HVCO is more than active than VCO.
