Abstract

Satoimo (Colocasia esculenta var. antiquorum) can be considered as an alternative food to support food diversification. The aim of this research was to obtain an optimum condition of the genetic transformation method of Satoimo taro through Agrobacterium-mediated genetic transformation using binary vector harboring gene construct of oshox4 and hpt gene as a selectable marker to produce transgenic plants. Plant materials that were used in this study were meristem, root, leaf, petiole, and basal stem. Transformation procedures were carried out using three different co-cultivation periods (1, 2, and 3 days) and different optical densities of A. tumefaciens cells (0,5 and 0,7). Furthermore, callus induction was performed on MS medium containing 2.4-D, cefotaxime, hygromycin and then regenerated on MS medium containing thidiazuron and hygromycin. The putative transgenic plantlets were selected on MS medium containing hygromycin and analyzed using PCR. The results showed that putative transgenic plants derived from the basal stem could survive on a selection medium containing hygromycin and based on PCR analysis some of them contained the oshox4 and hpt genes.

Abstract

Sarang banua plants are grown in Simalungun, North Sumatra, Indonesia, and have been used by the community as traditional medicinal plants. Sarang banua plant is a type of Clerodendrum fragrans Vent Willd, including the family Verbenaceae. This study aimed to determine the antidiabetic activity of the leaf extract of sarang banua (C. fragrans Vent Willd) in white male rats (Rattus novergicus) induced by alloxan. This study used a RAL design with seven treatments, namely (K0) standard feed, (K1) Na-CMC 0.5%), (K2) metformin, (K3) ethanol extract 100 mg/kg bw, 200 mg/kg bw (K4), 300 mg/kg bw (5), (K6) ethyl acetate extract 200 mg/kg bw and 300 mg/kg bw (K7). Groups K1 to K7 were induced by alloxan before being given treatment. Each treatment was replicated three times. The results showed that the application of leaf extract of the C. fragrans affected on reducing the blood glucose levels of alloxan-induced rats. The used of ethanolic extract of C. fragrans 100 mg/kg bw resulted in the highest percentage decrease in blood glucose (54.46 ± 5.60%) of hyperglycemic rats induced by alloxan, close to a positive control (56.63 ± 1.86%).

Abstract

he bioconversions of bioactive health supporting compounds using certain microorganisms have long been known, however it has not been widely applied in industrial scale to produce nutraceutical and products of high economic value. This review article will discuss the group of steroids, carotenoids and statins which were produced by microbial bioconversion using the various substrates and conditions. The information presented in this article were collected from scientific books and articles in national and international journals which can be validated and traced back to their sources through many sites such as google.com, google scholar, NCBI and Science Direct. From the information compiled in this article, it can be concluded that the bioconversion of bioactive compounds by microorganisms has shown positive results and potential to be further optimized and applied in an industrial scale to produce natural bioactive compounds as basic ingredients for nutraceutical and pharmaceutical products with high economic value.

Abstract

Chronically elevated levels of glucose in the blood can lead to various complications. As a result, it can accelerate the damage to various organ tissues in the body. Several measures are needed to maintain the stability of normal blood glucose levels to prevent tissue damage, as well as providing additional intake such as lime peel extract which is believed to have high flavonoid content in lowering blood glucose levels. For this reason, this study aimed to analyse changes in blood glucose levels by giving lime extract to alloxan-induced experimental animals. This study uses an experimental post-test control group design. The results showed increased in blood glucose levels in the positive control group (p < 0.005). In addition, the lime (Citrus aurantifolia Swingle) peel extract treatment group showed changes in blood glucose levels (p < 0.005). It was concluded that increasing the intake of lime peel extract can reduce blood glucose levels.
