This is a study on carotenoid extracted from ?Minyak Buah Merah? (Pandanus conoideus) in therapy simulation using high dose of β-carotene on two lymphocytes?that of a healthy subject and a leukemia patient. Superoxide production in mithocondrial lymphocyte as a result of β-carotene exposure was examined using a flow cytometer. The test finds that superoxide (a specific mitochondrial free radical) increases easier and faster in leukemic lymphocytes than in normal lymphocytes. The results of the study support previous meta-analysis studies that high dosages of β-carotene and vitamin E supplements as antioxidant should be discouraged because it increases all-cause mortality.

This study was carried out to analyze the serum vitamin A / carotene concentration among Indonesian full term neonates in relation to maternal nutritional status and nutrients intake. One hundred and eight couples' (mothers + neonates) were recruited for the study. The serum vitamin A/carotene concentrate ion was determined by High Pressure Liquid Chromotography (HPLC) and Ultraviolet Absorbance/Spectrophotometric method (IVACG, 1982) and the dietary nutrient intake of the mothers was analyzed using a 2 day/24 hours recall method. Seventy one (67%) of the neonates were suffering from low vitamin A level ( (20 g/dl), the rest 35 (33%) were at an adequate vitamin A level (>20 / g/dl) and 13 (12%) of the mothers were suffering from low vitamin A level ( <20 /4g/di), the rest 95 (88%) were at an adequate vitamin A level. That mean serum vitamin A/carotene of the neonates was lower than those of their mothers. The mean serum vitamin A of the mothers was 30.7 ,wg/dl - v.53 and mean serum carotene of the mothers was 124.23g/dl - 49.66. The study concluded that there was no significant correlation between serum vitamin A of the neonates and serum vitamin A of their mothers (p } 0.1). It was found that? serum vitamin .A concentration and serum carotene of the mothers were positively correlated; also maternal serum carotene was positively related to serum carotene of the neonates. The beta-carotene intake, fat intake, protein intake were positively related to serum vitamin A of the mothers. Further investigation using larger numbers of samples and more controlled method was suggested to -scrutinize the influences of gestational age, dietary nutrients intake on the serum of vitamin A/carotene of the mothers. The study also pointed out the importance of providing .the pregnant mothers with sound information about nutrition in pregnancy.

Hyaline membrane disease (HMD) and feeding intolerance (FI)are still problems of premature neonatal morbidity and mortality. Antenatal steroid administration has been recognized to reduce HMDand FImortality rates, but it is still not optimal and there are still different outcomes in neonates with similar gestational age, birth weight and treatment. Micronutrients of vitamin A, D₃ and zinc are known to play a roleon the lung and intestines of the fetusand neonates. This study aimed to find out the benefits of administration of vitamin A (beta carotene), vitamin D₃ and zinc accompanying antenatal steroids for lung maturation, in order to reduce the incidenceof HMD and FI. A randomized clinical trial was conducted on pregnant women 28-34 weeks of gestational age who were hospitalized for the preparation of preterm delivery on the indication of the mother or fetus. Both groups received dexamethasone for lung maturation. The intervention group received oral micronutrients, i.e., beta carotene 25,000 IU single dose, vitamin D₃ 50,000 IU single dose and 50 mg zinc per day for 3 days. The incidence of HMD, FI, HMD-FI and the relationship of serum retinol, 25(OH)D, zinc concentrationsin maternal and umbilical cord with HMD-FI were analyzed by Chi-Square or Fisher test, unpaired t or Mann Whitney test and paired t or Wilcoxon test between the intervention and control groups. The total subjects were 116 pairs of pregnant mothers and neonates (58 interventions and 58 controls). The incidence of HMDand FIin neonates in the intervention group were 7 (12.1%) and 9 (16.1%),which weresignificantly lower thanthe control group, 16 (27.5%) and 19 (34.5%). The HMD-FI neonates in the control group had lower serum retinol and 25(OH)D concentrations in maternal and umbilical cord than in the intervention group. Significant differences were only found at 25 (OH) D concentration. Conclusion: The incidence HMD and FI in the neonates intervention group were significantly lower than the control group. There was a relationship betweenserum retinol, 25(OH)D and zinc concentrations with HMD-FI outcome.

Red palm oil (RPO) mengandung antioksidan yang larut dalam lemak seperti karotenoid (α dan β-karoten, likopen), vitamin E (dalam bentuk α, β, dan δ tokotrienol dan tokoferol), dan ubikuinon. Red palm oil (RPO) dapat digunakan sebagai upaya mencegah stunting dan kekurangan gizi karena nilai gizi yang jauh lebih tinggi daripada minyak goreng yang beredar di pasaran. Akan tetapi, belum terdapat banyak studi mengenai pemanfaatan red palm oil (RPO) dalam hal tersebut. Penelitian ini bertujuan untuk memperoleh formula emulsi dari red palm oil (RPO). Sediaan emulsi red palm oil (RPO) dibuat menggunakan 5% sukrosa ester palmitat untuk mengemulsifikasi 5% (F1), 10% (F2), dan 15% (F3) red palm oil (RPO) dengan madu untuk menambah kestabilan, kemudian dilakukan karakterisasi fisik untuk mengetahui stabilitas emulsi selama 12 minggu. Hasil menunjukkan bahwa selama 12 minggu ketiga formula emulsi stabil berdasarkan parameter organoleptis, pH, homogenitas viskositas, ukuran partikel, dan zeta potensial. Hasil uji hedonis pada 30 orang responden menunjukkan bahwa formula F1 paling disukai para responden. Dengan demikian, dalam penelitian ini formula F1 menghasilkan hasil uji yang paling baik. ......Red palm oil (RPO) contains fat-soluble antioxidants such as carotenoids (α and β-carotene, lycopene), Vitamin E (in the form of α, β, and δ tocotrienols and tocopherols), and ubiquinone. Red palm oil (RPO) can be used as an effort to prevent stunting and nutritional deficiencies due to its significantly higher nutritional value compared to cooking oils available in the market. However, there haven't been many studies regarding the utilization of red palm oil (RPO) in this matter. This study aims to obtain an emulsion formula from red palm oil (RPO). The red palm oil (RPO) emulsion preparations were made using 5% sucrose ester palmitate to emulsify 5% (F1), 10% (F2), and 15% (F3) red palm oil (RPO) with honey to enhance stability. Subsequently, a physical characterization was conducted to determine the emulsion's stability over a period of 12 weeks. The results showed that all three emulsion formulas remained stable over the 12-week period based on organoleptic parameters, pH, viscosity homogeneity, particle size, and zeta potential. Hedonic testing results from 30 respondents indicated that Formula F1 was the most preferred by the respondents. Therefore, in this study, Formula F1 yielded the best test results.

Karotenoid adalah pigmen alami tidak larut air yang terkenal karena bersifat antioksidan dan merupakan prekursor vitamin A. Beta-karotena merupakan provitamin A terbaik yang umum digunakan dalam industri sebagai pigmen oranye-merah untuk membuat berbagai produk makanan. Pada penelitian ini beta-karotena diekstraksi dari mikroalga dengan jenis spirulina yang ditumbuhkan pada media zarrouk dengan penambahan limbah sawit dalam berbagai persentase. Kandungan karotenoid dalam mikroalga diekstraksi dengan menggunakan metode maserasi dengan pelarut etanol, metanol, heksana, dan diklorometana. Berdasarkan hasil FESEM, terdapat perubahan ukuran granula pada mikroalga yang ditumbuhkan dalam variasi persentase limbah sawit (POME) sebagai media. Diklorometana merupakan pelarut ekstraksi terbaik berdasarkan hasil penentuan kadar beta-karotena dengan spektrofotometer Vis. Persentase limbah sawit dalam media berbanding terbalik dengan kadar beta-karoten dalam mikroalga. Limbah sawit pada media mikroalga menghambat pembentukan pigmen dan menurunkan aktivitas antioksidan ekstrak, berdasarkan metode DPPH. ......Carotenoids are natural, insoluble pigments that are famous for their antioxidant properties and are precursors of vitamin A. Beta-carotene is the best pro-vitamin A which is commonly used in industry as an orange-red pigment to make various food products. In this study, beta-carotene was extracted from microalgae, spirulina, grown in zarrouk media with the addition of palm oil waste in various percentages. Carotenoid content in microalgae was extracted using the maceration method with ethanol, methanol, hexane and dichloromethane solvents. Based on FESEM results, there were changes in microalgae granule size that grown in variety percentages of palm oil waste (POME) as medium. Dichloromethane was the best extraction solvent based on the results of determining beta- carotene content using a Vis spectrophotometer. The percentage of palm waste in the media was inversely proportional to the beta-carotene content in microalgae. Palm waste in microalgae medium inhibits pigment formation and reduces antioxidant activity, based on the DPPH method.
