Abstract

The mangrove plant have been long used the people for traditional medicine to cure various diseases, one of them to cancer therapy. Investigation the anticancer potent of R. mucronata has not been carried yet. This research was aimed to toxicity test of R. mucronta leaves extracts againts Artemia salina Leach, then cytotoxicity test of R. mucronata leave extracts againts Myeloma cancer cells. The extraction of R. mucronata leaves was peformed by maseration with ethanol. The ethanol extracts was partitioned with chloroform, ethylacetate and methanol. The ethanol extracts of R. mucronata leaves respectively was examined their toxicity againts A. salina Leach larv. The toxic exctracts was examined their citotoxicity againts Myeloma cells. The ethanol extract of R. mucronata leaves has toxic character because has LC50 < 1000 mg/mL. Citotoxicity test againts Myeloma cells showed that the chloroform fraction of ethanol extract of R. mucronata leaves have a high activity against Myeloma cell, LC50 value equal to 28,72 mg/mL. Phytochemical study showed that the active fractions contained terpenoid and alkaloid.

Abstract

The non-edible oil from nyamplung seed (Callophyllum inophylum L.) has been widely used as a soap ingredient. The soap production from nyamplung seed oil with the addition of antioxidant and fragrance had been carried out in this research. Ketapang (Terminalia catappa L) fruit extract and Cardamom (Amomum compactum) were used as antioxidant and fragrance substances, respectively. The variation of concentration of antioxidant and fragrance has been carried out to obtain the high quality of soap. Characterization was done to know the quality of soap in accordance with SNI 06-4085-1996. The antioxidant activity was analyzed using DPPH (1,1-diphenyl-2-picrylhydrazyl). The results showed that the addition of 1% ketapang fruit extract and 3% cardamom fragrance exhibited the best characteristics. The antioxidant activity test showed that the IC50 value of the best antioxidant soap is 79.51 ppm, indicating that the soap is a strong category

Abstract

Indonesia merupakan negara megabiodiversitas yang banyak mengandung kekayaan alam, salah satunya alga merah. Alga merah (Glacillaria verrucosa) mengandung senyawa fikosianin, fikoeretin dan karotenoid yang berperan sebagai antioksidan. Penelitian ini dilakukan untuk mengetahui potensi bioaktif ekstrak alga merahuntuk terapi hewan coba tikus putih (Rattus novergicus) berdasarkan kadar malondialdehida (MDA) dan gambaran histologi paru. Metode penelitian yang dilakukan meliputi ekstraksi alga merah dan karakterisasi, induksi  hewan coba (R. novergicus) dengan formalin, kemudian terapi ekstrak alga merah dengan variasi dosis. Berdasarkan uji fitokimia, analisis dengan FTIR dan LCMS, ekstrak alga merah mengandung senyawa flavonoid, terpenoid, alkaloid, β-karoten , β-apo-8’-carotenal dan α-tokoferolyang berperan sebagai antioksidan. Formalin dapat meningkatkan kadar MDA serta menyebabkan kerusakan sel epitel bronkus dibandingkan dengan keadaan normal. Pemberian terapi dengan dosis yang sesuai akan menurunkan kadar MDA dan memperbaiki keadaan sel epitel bronkus. Berdasarkan pengamatan parameter penelitan, diketahui bahwa dosis optimum yang sesuai untuk terapi kanker paru adalah 100 mg/kg BB

Abstract

This study evaluated the free radical scavenging activity in ethanolic extracts from 20 accessions of Curcuma aeruginosa. The radical scavenging activity of the extract accessions was investigated with 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical. IC50 values for DPPH radical scavenging activity ranged from 89.81 to 505.65 µg mL-1. Based on IC50 values, twenty accessions of C. aeruginosa can be divided into three groups: strong (two accessions); moderate (seventeen accessions); and low (one accession) of DPPH scavenger. Sukoharjo (SH) and Muara Bungo (MB) showed promising accessions for antioxidant potential, thus these accessions important to selection for future breeding program in pharmaceutical products.

Abstract

Lipases are valuable biocatalysts because they act under extremely mild conditions, are stable in organic solvents, show broad substrate specificity and exhibit high stereoselectivity. Lipases play important role in various industries such as detergent, cosmetics, flavor, pharmacy and synthesis of organic compounds. The increasing of lipases requirements in industries is goading research to get new lipases resources commited. One of potential lipase resource is Azospirillum sp.JG3 bacteria from Microbiology Laboratory of Biology Faculty University of Jenderal Soedirman. The specific targets of this research are to get crude extract of lipase and investigate its biochemical characteristics. The method used were rejuvenation of Azospirillum sp.JG3 bacteria, inoculum production, determination of optimum production time and bacterium growth phase, extraction and production of lipase to get crude extract, and characterization the biochemical properties of lipase crude extract. The research resulted that crude extract of lipase from Azospirillum sp.JG3 had optimum temperature at 40 °C and optimum pH at pH 7. The lipase was a metalloenzyme with Ca2+ as its cofactor. The lipase was stable in three organic solvents tested, (chloroform, n-hexane and ether).

Abstract

The study of xanthone derivatives as cytotoxic agents in cancer is increasing. This study was conducted to explore the Quantitative Structure-Activity Relationship (QSAR) of xanthones as cytotoxic agents in HepG2 cells, to find compounds with better potency. The data set were taken from the previous study, involving 26 xanthone derivates and their cytotoxic activities in Inhibitory Concentration 50% (IC50). The parameters (descriptors) were obtained from quantum mechanics calculation using semiempirical AM1 method and QSAR models determined with principle component regression, with log (1/IC50) as a dependent variable and five latent variables as independent variables. From the 26 main descriptors, PCR reduced them to five latent variables (1st– 5th LV). The QSAR analysis gave the best model as follows: log (1/IC50) = 4.592 – 0.204 LV1 + 0.295 LV2 + 0.028 LV3 (n = 26, r = 0.571, SE = 0.234, Fcount/Ftable ratio = 1.165, PRESS value = 3.766). The study concluded that the descriptors contributed to anticancer activity were volume, mass, surface area, log P, dipole moment, HOMO energy, LUMO energy, and atomic net charge of some atoms. Modifications of substitution that would contribute to cytotoxic activity can be performed at phenyl ring A and C, but not at B.
