The most common human pathogen that colonizes in a third of healthy people around the world are Staphylococcus aureus, and one of the materials allegedly able to overcome the pathogen is resin. Resin has been used in folk medicine for thousands of years to treat diseases. The antimicrobial activity of natural resins can be associated with a variety of organic compounds contained in them such as diterpenoids and triterpenoids. This research aimed to explore the antibacterial and antioxidant activities of Pinus merkusii, P. oocarpa, P. insularis, Agathis loranthifolia resins and essential oil. Resin was separated by distillation process to get essential oil and the residue was extracted using n-hexane, ethyl acetate (EtOAc), and methanol (MeOH). Antioxidant activity was performed by DPPH (1,1diphenyl-2-picryl hydrazyl) radical scavenging method. The antibacterial activity of resins and essential oil of the samples determined using the disc diffusion method against Staphylococcus aureus and Escherichia coli. The results showed that the yield of resin extract was ranging from 8.44 % to 95.56%. All extracts and essential oil could not inhibit E coli growth but inhibit the S. aureus growth. This experiment concluded that resin n-hexane extract from P.oocarpa was the most potent as antibacterial activity against S. aureus. All of the samples used had less potential antioxidant activity compared to positive control ascorbic acid. Result of this study show that pine resin from Indonesia has potential as an antibacterial agent.

The aim of this study was to determine the yield and phytochemicals, antioxidant activity, and sunscreen of the Gyrinops versteegii leaf extracts. The leaf simplicia was extracted using soxhletation method with multilevel polarities of solvent (n-hexane, ethyl acetate, and metanol). The analysis of phytochemical extracts has been carried out the qualitatively and quantitatively. The antioxidant activity testing was performed in vitro through the effective concentration (EC50) extract in capturing DPPH radicals. Sunscreen activity has been done through testing sun protection factor (SPF). The result showed that the yield of n-hexane extract, ethyl acetate, and methanol extracts were 7.83, 5.46, and 6.77% respectively. The phytochemical analysis showed that the ethyl acetate and methanol extracts were strongly detected containing antioxidant compounds such as p-hydroquinone, flavonoid, and tannins with the total phenol of the ethyl acetate and methanol extracts were 3.40 and 4.27% respectively. The n-hexane extract detected contains weakly the antioxidant compounds with the total phenol was 0.45%. The methanol extract is the highest antioxidant activity (EC50 14.46 μg ml-1) and has ultra sunscreen activity (SPF>15).Keywords: antioxidant, extractive, G. versteegii, sunscreen

Active compounds utilization of its extractives for cosmetic products increase the value added of mangium tree. The purpose of this study was to determine the antioxidant and an inhibitor tirosinase activities of methanol extract of the various parts of mangium tree. Phytochemical properties of the best extract were also anlayzed. Extraction was conducted by soxhletation in methanol for 12 hours. The antioxidant and tyrosinase inhibitory activities of the extracts were tested in vitro to radical of 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging and inhibition to tyrosinase enzyme. The results showed that leave resulted in the highest methanol ectract followed succesively by bark, heartwood, and sapwood the value of 10.7; 4.4; 2.5; and 0.9%, respectively. The highest antioxidant activity was bark extract and followed by leave, heartwood, and sapwood extracts with EC50 values respectively of 8.3; 26.7; 66.9; and 137.9 ppm. Only bark extract which classified as an active tyrosinase inhibitor with IC50 value of 257.8 ppm in the difenolase reaction. The IC50 value of the positive control (kojic acid) was 116.7 ppm. The other extracts relatively inactive as a tyrosinase inhibitor because their IC50 values > 1000 ppm. The qualitative analysis detect the methanol extract of mangium bark as the best extract containing phenolic compounds (phenol hirokinon, flavonoids, and tannins) and alkaloids which were thought to contribute to the high antioxidant and tyrosinase inhibitor activities.Keywords: Acacia mangium, antioxidant, extracts, tyrosinase inhibitor

This study was undertaken primarily to isolate and identify substances from resin of Shorea javanica K. et. V. that might be responsible to inhibit the termite activity of Coptotermes curvignathus Holmgren. Approximately 500 gram of dried-resin was extracted with acetone solvent. The acetone extract was then fractionated into n-hexane, diethyl ether, ethyl acetate, and insoluble fraction (residue). The no-choice bioassay test was carried-out by treating paper discs with extracts at the concentration of 2.0%, 4.0%, 6.0%, 8.0%, 10.0%, 12.0% (W/W), and 0.0 % as control. The bioassay test showed that n-hexane and diethyl ether soluble fraction exhibited highest antitermic properties at Lethal Concentration (LC)50 value of 1.62% and continuation fraction showed N3 of n-hexane fraction an EE1 of diethyl ether fraction exhibited highest toxicity at LC50 value of 1.23 % and 1.65%. Further investigation of the n-hexane soluble fraction by using CC, GC-MS, FTIR, UV-Vis, and NMR led to the isolation and identification of the main compound, namely friedelin, while the diethyl ether soluble fraction contains vulgarol B; 3,4-Secodamar-4(28)-en-3-oic acid; (7R,10S)-2,6,10-Trimethyl-7, 10–epoxy-2,11-dodecadien; and junipene (decahydro-4,8,8-trimethyl-1,4-methanoazulene)

Diabetes mellitus (DM) merupakan penyakit gangguan metabolik yang menjadi masalah utama kesehatan di dunia termasuk Indonesia. Penelitian ini bertujuan untuk menetapkan rendemen zat ekstraktif tanaman jabon, aktivitas antidiabetesnya secara in vitro terhadap enzim -glukosidase serta menganalisis kandungan kimia ekstrak teraktifnya Ekstrak jabon dihasilkan dari proses maserasi dengan etanol 95% pada berbagai bagian pohon (daun, kulit, kayu). Hasil penelitian menunjukkan bahwa kadar ekstrak tertinggi terdapat pada bagian daun (16,5%), diikuti bagian kulit (4,62%) dan kayu (2,04 %). Berdasarkan uji aktivitas penghambatan enzim -glukosidase, ekstrak etanol daun jabon merupakan ekstrak teraktif dengan nilai IC50 7,24 µg ml-1 (sangat aktif), sedangkan ekstrak etanol bagian kulit dan kayu tergolong tidak aktif (IC50 > 100 µg ml-1). Hasil uji fitokimia secara kualitatif menunjukkan kelompok senyawa yang terkandung di dalam ekstrak etanol daun jabon adalah flavonoid, hidroquinon, saponin, tannin, alkaloid, terpenoid dan steroid yang diduga berperan dalam menghambat aktivitas enzim -glukosidase. Analisis GCMS mendeteksi adanya senyawa fenolik asam quinat dan katekol serta turunan asam lemak (asam heksadekanoat metil ester) yang diduga memiliki aktivitas antidiabetes. Berdasarkan hasil tersebut, ekstrak etanol daun jabon sangat berpotensi sebagai sumber obat andiabetes.

The purpose of this study was to analyze the physicochemical stabilities and in vivo antiaging properties of the cream formulas of F1, F2, and F3 which contained the active compound of 0.1% 0.18, and 0.36%, respectively. The active compound was the combination of ethyl acetate fraction of Toona sinensis, Centella asiatica, and Acacia mangium leaf (1:2:1). For physicochemical stability tests (color, odor, acidity, and antioxidant activity), the creams were stored for 21 days in the refrigerator, room temperature, and extreme temperature (±40 ⁰C). For in vivo antiaging test, the mice skin were smeared with cream and UV irradiated for 15 minutes per day. After two and four weeks, the mice skins were biopsied. The results showed that the physicochemical properties of creams stored in the refrigerator were stable. The storage of creams at room and extreme temperature decreased the physicochemical properties. The application of cream formulas on mice skin after two to four weeks were able to increase the thickness of epidermis, but has not been able to increase the collagen skin of mice.Keywords: Acacia mangium, Centella asiatica, ethyl acetate fraction of leaf, physicochemical and antiaging properties of cream, Toona sinensis
