Nutritional problems still become a crucial issue in Indonesian public health. Fulfillment of nutritional balance is expected to improve life quality. In humans, one of the nutrients that play a role in the growth of brain and nervous system functions is PUFA, such as omega-6 and omega-3. Besides, fulfillment of nutritional balance can prevent some diseases; especially linoleic acid used to prevent some diseases. Linoleic acid is an omega-6 and essential fatty acid. Linoleic acid is the main essential fatty acid because it is the precursor for GLA, DGLA, and AA. Omega-6 works with omega-3 and some omega-3 benefits are supported or can arise by omega-6 presence. Studies reveal that watermelon contains high linoleic acid. This study aimed to determine the optimum temperature and ratio of fatty acids: urea for the isolation of linoleic acid from watermelon seed oil. The method used was urea inclusion with a variety of temperatures (-6oC, 6oC, 18oC) and the ratio of fatty acid: urea (1:1; 1:3; 1:5). The results showed the optimum watermelon seed oil linoleic acid isolate at 18oC and the ratio of fatty acids: urea 1:5 with linoleic acid purity (%) of 82.53%.

Medicinal plants are natural sources of effective antimicrobials from natural products. Tithonia diversifolia (Asteraceae) is a conventional herb that can be used for the treatment of malaria, wounds, and other diseases with biological properties such as antioxidant, antimalarial, antidiabetic, antibacterial, and anti-hyperglycemic. Research on Tithonia diversifolia leaf extract as an antibacterial has been widely carried out. However, its use as a natural antibacterial is rarely studied, especially on flowers and roots. This study aimed to test the antibacterial activity of leaf, flower, and root extracts of the Tithonia diversifolia plant in various solvent fractions. The methods used in this research were Antibacterial Testing with Agar Diffusion and Direct Bioautography Methods, while the solvent fractions used were petroleum ether, chloroform, and ethyl acetate. The results showed that the crude extract of Tithonia diversifolia leaves, flowers, and roots for petroleum ether, chloroform, and ethyl acetate fractions contained antibacterial compounds. They could inhibit the growth of E. coli, P. aeruginosa, S. aureus, and B. subtilis bacteria, with inhibitory activity in chloroform fraction, which was better than in petroleum ether and ethyl acetate fractions. The results of the bioautography test showed that the inhibition was good on gram-positive bacteria with the highest number of spots in the chloroform fraction for the crude leaf and flower extract samples.

Ocimum gratissimum L. atau kemangi hutan merupakan salah satu jenis tanaman yang banyak dimanfaatkan dalam bidang pengobatan tradisional. Biji dari tanaman kemangi hutan diduga mengandung senyawa aktif antioksidan berupa skualena yang banyak digunakan dalam industri farmasi. Sumber utama senyawa skualena adalah minyak hati ikan hiu, kenyataan ini memperkuat alasan perburuan ikan hiu semakin marak. Skualen nabati yang bisa ditemukan pada beberapa jenis tumbuhan menjadi salah satu alternatif untuk mengurangi penggunaan skualena dari minyak hati ikan hiu. Penelitian ini bertujuan untuk menentukan hasil rendemen, sifat fisiko-kimia serta menganalisa komponen penyusun minyak biji kemangi hutan dengan metode Gas Chromatography-Mass Spectrometry (GC-MS). Tahapan penelitian meliputi ekstraksi minyak biji kemangi hutan menggunakan alat soxhlet dengan pelarut heksana dilanjutkan dengan proses pemurnian yang meliputi degumming dan netralisasi. Tahap terakhir berupa analisa GCMS minyak hasil ekstraksi. Hasil penelitian menunjukkan bahwa rendemen minyak biji kemangi hutan setelah pemurnian diperoleh sebesar 5,106 ± 0,10%, berwarna kuning pucat berbau khas kemangi hutan, kadar air minyak 0,06%; massa jenis minyak 0,84 g/ml; bilangan asam 0,416 ± 0 mg KOH/g minyak; bilangan peroksida 0,028 ± 0 meq O2/g minyak; dan bilangan penyabunan 219,648 ± 2,608 mg KOH/g. Sifat fisikokimia tersebut telah memenuhi kriteria SNI. Hasil analisis GC-MS menunjukkan bahwa minyak biji kemangi hutan didominasi oleh empat komponen utama yaitu skualena (58,85%), asam propanedioat (16,69%), asam palmitat (14,91%), dan metil heksanoat (9,55%). Pemurnian minyak biji kemangi hutan meningkatkan kandungan skualena dari 1,07% menjadi 58,85%. The Effect of Purification on The Quality and Content of Forest Basil Seed Oil (Ocimum gratissimum L.). O. gratissimum L. or forest basil is a plant that is widely used in traditional medicine. Forest basil’ seeds suspected contain active antioxidant compounds that have the shape of squalene, and it is widely used in the pharmaceutical industry. The main source of the squalene compound is shark liver oil; this fact reinforces the reason for shark hunting increasingly widespread. Plant Squalene, which can be found in many plant species, is one of an alternative to reduce the use of squalene from shark liver oil. The aims of this work are to determine the yield, physicochemical properties and to analyze the components of forest basil’seed oil using Gas Chromatography-Mass Spectrometry (GC-MS). The stages of this work included extraction of forest basil seeds using Soxhlet extractor in hexane solvent, followed by a refining process includes degumming and neutralization. The final step is analyzed forest’ basil seed oil obtained using GC-MS. The results showed that the yield of forest basil seed oil obtained in the amount of 5.106 ± 0.10 %, a pale yellow color, with a specific aroma of basil forests, the water content of 0.06% oil; oil density 0.84 g / ml; an acid number of 0.416 ± 0 mg KOH / g of oil; peroxide number of 0.028 ± 0 meq O2 / g of oil; and a saponification number of 219.648 ± 2.608 mg KOH / g of oil. The physicochemical properties have fulfilled SNI criteria. GC-MS analysis resulted that forest basil’ seeds oil are dominated by four main components, namely squalene (58.85%), propanedioic acid (16.69%), palmitic acid (14.91%), and methyl hexanoate (9.55%). Purification forest basil seed oil increases squalene of 1.07% to 58.85%.

Resistance to temephos as a larvicide of A. aegyptimosquitoes has occurred in Indonesia. Therefore, it is necessary to look for other active compounds that can act as larvicides, but also environmentally friendly. This study used leaf and roots extract of T. erectahexane and acetone fraction as larvicide. The process begins with drying followed by extracting samples (leaves and roots of T. erecta) each with hexane and acetone solvents. Test solutions were made with a concentration of 0, 0.0075, 0.015, 0.03, and 0.1% (w/v) of the extract produced. Larvicide test was carried out referring to WHOPES by observing the mortality of instar larvae 3 and 4 in each extract. The results obtained showed the mortality percentage of larvae increased with increasing concentration and exposure time in both types of larvae. The lowest LC 50 was obtained from the root extract of hexane fraction (37 ppm) for 3rd instar larvae and acetone fraction (61 ppm) for instar 4 larvae. Keywords: Larvae, A. aegypti, T. erecta.

Cucurbitaceae is known as a source of vegetable oil that can be used in the fields of food, medicine, and cosmetics. Several studies showed that vegetable oil from the Cucurbitaceae contains squalene. Squalene is a high-economic value compound that was originally found in shark liver oil. This compound is proven to be very beneficial for health and cosmetics. The objectives of the study are to determine the fatty acid profile and squalene content of cucumber seed oil using the Gas Chromatography-Mass Spectrometry (GC-MS) method. Starting with the preparation of cucumber seeds by drying the clean seed in an oven at 60 0C for 1 hour, then the seeds were extracted using 2 methods namely maceration and a continuous extraction method with a soxhlet extractor. The yield of crude oil obtained by the soxhlet extractor is higher than maceration, which was 19.38 ± 0.94%, yellow colour, and distinct aroma, 2% water oil content; oil density of 0.96 g/mL; free fatty acid levels of 3.51%; an acid value of 4.97 mg NaOH/g oil; and peroxide value of 0.82 meq O2/g oil. The results of the GC-MS analysis showed that cucumber oil was composed of 3 main components namely palmitic acid, linoleic acid, and squalene. Keywords: Cucumber seed oil, Cucumis sativus, fatty acids, squalene.
