Abstract

Hydrogenolysis of biomass-derived furfural (FFR) to 1,5-pentanediol (1,5-PeD) is a critical route forsustaining fine chemicals. Development of nickel-yttrium oxide catalysts has been successfully synthesized with two different treatments. The first catalyst, Ni-Y(n)HT catalyst, was synthesized by direct reduction from nickelyttrium hydroxides mixture. The mixture of nickel-yttrium hydroxides from the same preparation procedure was calcined as a pretreatment and subsequence reduced using hydrogen gas giving Ni-Y2O3(n)T catalyst. The reduced of catalysts consists of nickel(0) and yttrium oxide with the difference in crystallinity. The difference in catalytic performance between both type catalysts showed in the production of 1,5-PeD from hydrogenolysis of FFR. Catalytic behavior of catalysts is similar and Ni(0)-Y2O3 boundaries is critical for cleavage C-O bond of furan ring.

Abstract

Fig leaves (Ficus carica) are known as the source of antioxidants. Antioxidant properties arise causedby the presence of phenolic compounds, flavonoid is one of several types of phenolic compounds. Usually people takes advantage of fig leaves by brewing them with boiled water, like tea. The use of high temperature was feared to decompose the phenolic compounds of fig leaves because these compounds are not resistant to heat. Decomposing the phenolic compounds will decrease their antioxidant potential. This research was to determine the total phenolic content dan total flavonoid content of fresh dan dried fig leaves with boiled water. Folin-Ciocalteu Method was used to determine the total phenolic content dan AlCl3 Colorimetric Method was used to determine the total flavonoid content. Total phenolic content of fresh dan dried fig leaves brew with boiled water were 0.0113±0.0004% dan 0.0076±0.0004% respectively. Total flavonoid content of fresh dan dried fig leaves brew was 0.0105±0.0003% dan 0.0025±0,0002% respectively. From the data analysis results with Two Way Anova, it can be concluded that the preparation of fig (fresh dan dried) simplicia significantly affects the total phenolic content dan total flavonoid content.

Abstract

Candida albicans is a normal flora of the respiratory tract mucous membranes, gastrointestinal tract, and female genitalia that it causes oral ulceration, vulvovaginitis, skin infections, nail infections, lung infections and chronic mucocutaneous candidiasis. Salam (Syzygium polyanthum) is a plant that is widely used as a food seasoning or as an herbal medicine such as antifungi. The purpose of this study is to know antifungal activity of water juice of bay leaf (Syzygium polyanthum) on Candida albicans. This study was conducted at laboratory pharmacognosy and microbiology Academy of Pharmacy of Putra Indonesia Malang using experimental research methods. This study steps consisted of manufacture water juice of bay leaf with 100% and 50% concentration, phytochemical screening, and then tested antifungal activity for Candida albicans using method diffusion of pit. The results of this study can be concluded that water juice of bay leaf has not antifungal activity because no inhibition zone which isindicated by the absence of clear zone around well in the petri dish. Further research is needed on antifungal activity using other extract method.

Abstract

Temu giring (Curcuma heyneana) has been used for a long time by Indonesian society to maintain the skin health. The phenolic content of temu giring has an efficacy as an antioxidant. Fermentation has been known to increase the antioxidant activity due to the increasing of phenolic content. This study aims to determine the comparison of total phenolic content of fresh and fermented temu giring (Cucuma heyneana) extract. The research procedures include the extract filtration, fermentation, phytochemical screening, total phenolic content determination, data analysis and drawing conclusion. Temu giring extract preparation was performed by filtering the temu giring with water until obtaining the extract. Then, the fermentation was conducted using Lactobacillus bulgaricus for 24 hours at 37°C. The organoleptic testing, including dye, smell, taste and pH, was performed. Finding shows that the fresh and fermented extract pH has decreased. The phytochemical screening of fresh and fermented temu giring indicates that it positively contains phenolic and flavonoid. From the total phenolic content determination by Folin Ciocalteu methods of fresh temu giring, the amount of 9.476±2.04 mgGAE/gram was obtained and from the total phenolic content determination of fermented extract, the amount of 61.333±1.643 mgGAE/gram was obtained.

Abstract

Fig Leaves contain flavonoids that can be used as antimicrobials. Fermentation with kombucha is expected to increase antimicrobial activity. The aim of this research is to observe antimicrobial activity of Fig Leaves sour tea against several microbes, such as Staphylococcus aureus, Escherichia coli, Lactobacillus casei and Candida albicans. The sour tea is made through 12 days fermentation of Fig Leaves with kombucha. Antimicrobial assay has been performed using the agar well diffusion method. From the test results, the mean of inhibition zone against Escherichia coli is 6,97 mm, Staphylococcus aureus is 5,5 mm, Lactobacillus casei is 5,29 mm, and Candida albicans is 0,37 mm. Based on the research results, Fig Leaf sour tea can be used as an antimicrobial agent, especially as an antibacterial.
