Penapisan Galur Haploid Ganda Padi Gogo Hasil Kultur Antera untuk Toleransi terhadap Cekaman Aluminium

Aluminum (Al) toxicity is one of the most important yield-limiting factors for upland rice grown on acid soils. Since many small farmers may have difficulty in soil liming, the genotypes tolerant to soil acidity and aluminum toxicity should be developed. Anther culture can substantially speed up new variety development through recombination of parental characters in early generations and immediately homozygous lines were upon chromosome doubling. The Doubled haploid (DH) rice lines were screened under both nutrient solution containing either 0 or 45 ppm Al and acid soils containing either low or high-Al saturation. The relative root length (RRL) was determined at 14-day-old stage to characterize genotypes for Al-tolerance in nutrient solution. The relative grain weight (RGW) was determined to characterize genotypes for Al-tolerance in soils conditions. The results of this study indicated that Al reduced root elongation. The differential tolerance for Al among genotypes was found to be highly significant for RRL. Of the 120 genotypes tested, 16, 77 and 27 genotypes were found to be Al-tolerance, moderate and sensitive in term of RRL respectively. KRGM4, JTGR13, JTGR17, JTGR18, JTKR1, JTKR5, GRGM4, GRGM6, GRGM9, GRGM14, GRGM25, GRJT11 and SGJT27 lines were consitently Al-tolerance under both nutrient solution and acid soils. The RRL of doubled haploid upland rice lines in nutrient solutions were strongly correlated with RGW in acid soils

Multivariate calibration of antioxidant activity of M. charantia fruits and its fourier transform infrared spectroscopy based fingerprinting

Momordica charantia is widely consumed edible fruit. The food and pharmaceutical industries use it as a natural antioxidant. However, the quality control of M. charantia-based medicinal products is questionable due to the complexity of metabolites in this fruit. Hence, this study has developed a statistical model in predicting the antioxidant value through the 2, 2-diphenyl-1 picrylhydrazyl radical scavenging activity and ferric reducing antioxidant power based on infrared spectroscopy with attenuated total reflectance. This technique was reliably used for quality control. Six ethanol extracts (0, 20, 40, 60, 80, and 100% in water) of this plant’s fruit were prepared. The radical scavenging and ferric reducing antioxidant power activities were measured and the chemical profiling of the extracts was fingerprinted by infrared spectroscopy between 4,000 and 600 cm−1 at a resolution of 4 cm−1. Statistical analysis was developed by correlating the bioactivity and infrared spectra of each extract using orthogonal partial least square discriminant analysis. The C–N, C=O, C–O, C–H, and OH infrared signals were positively correlated with biological activity. The antioxidant activity of the fruit of M. charantia may be due to the presence of several antioxidants that work synergistically

Cytotoxic, anti-inflammatory and adipogenic effects of selected flavonoids on cell lines

Naturally-occurring flavonoids have tremendous potential for producing of new therapeutic agents that provide many benefits to mankind.This study focused on the evaluation of the in vitro cytotoxic, anti-inflammatory and adipocyte differentiation effects of the selected flavonoids which were inophyllum D, calanone, and isocordataoblongic acid from Calophyllumsymingtonianum as well as morelloflavone from Garciniaprainiana on MCF 7 human breast cancer cells, RAW 264.7 macrophages and 3T3-L1 pre-adipocytes respectively. The cytotoxicity study on MCF 7 human breast cancer cells was conducted by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Meanwhile, the study of anti-inflammatory effects in RAW 264.7 macrophages and adipogenic effects on 3T3-L1 pre-adipocytes were conducted through nitrite determination assay and induction of adipocyte differentiation respectively. In the cytotoxicity study, inophyllum D was the only compounds that exhibited significant cytotoxic effect against MCF 7 human breast cancer with IC50 of 84 μg/mL. Further, all the compounds have shown anti-inflammatory effects in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages with inhibition of nitrite concentration as compared to the positive control. Besides, all the compounds in the range of the tested concentrations also produced adipogenic effects on 3T3-L1 pre-adipocytes and this may suggest that they exhibited potential anti-hyperglycemic property which mimicking the insulin action. Thus, this study may provide significant implication in the discovery of the potential of these selected flavonoids as alternative anti-cancer, anti-inflammatory and anti-hyperglycemic drugs
