Abstract Free radicals can cause various degenerative diseases such as cancer and cardiovascular disease. Flavonoids have antioxidant abilities that inhibit damage from free radicals. The roselle antioxidant mechanism is associated with high flavonoid content. Red and purple roselles are two varieties of roselle (Hibiscus sabdariffa L.) cultivated in Indonesia. The aim of this research was to analyze the differences in flavonoid content and antioxidant activity in the calyces of two varieties of roselle (Hibiscus sabdariffa L.), red and purple. Total flavonoid analysis and antioxidant activity testing were done by spectrophotometry in the visible region. Total flavonoid content was analyzed by pretreatment with aluminium chloride and sodium acetate. Antioxidant activity was tested with 2,2-diphenyl-1-picrylhydrazyl. The total flavonoids for both red and purple roselle calyces ethanolic extract were 27.55 and 39.18 mg quercetin equivalent per gram. The half maximal inhibitory concentration values obtained for both red and purple roselle calyces ethanolic extract a were 51.59 and 42.17 μg/mL. The total flavonoid content and antioxidant activity of purple roselle calyces ethanolic extract was higher and stronger than red roselle calyces ethanolic extract.

Objectives. There has been a rapid increase in the number of diabetic patients since the past few decades in developed and developing countries. This rapid increase is accompanied by alarming costs of treatment. α-Glucosidase inhibitors are one of the most effective drugs employed for the reduction of postprandial hyperglycemia to manage Type 2 diabetes mellitus. Additionally, flavonoids, a group of natural substances, which are widely distributed in plants and possess variable phenolic structures, exhibit outstanding hypoglycemic activity and are considered as potential α-glucosidase inhibitors. In Vietnam, Persicaria pulchra (Bl.) Soják (P. pulchra) is employed in traditional medications. It possesses high flavonoid contents and its anti-diabetes ability has been hypothesized, although it has attracted less attention for investigation. Hence, the aim of this study is to optimize the condition of the P. pulchra extract to obtain the highest total flavonoid content and measure the bioactivities of P. pulchra, such as the anti-α-glucosidase and antioxidant activities.Methods. The effects of the extracting conditions, including the temperature, extraction time, liquid-to-solid ratio (LSR), and ethanol (C2H5OH) concentration, on the total flavonoid content are investigated via experiments and analyzed by the response surface methodology (RSM). Concurrently, the optimal extraction also determines the anti-α-glucosidase and antioxidant activities.Results. The optimal extraction condition for the highest flavonoid content (530 mg quercetin/g) is determined in 60 min, at 53°C, with LSR of 9.46 g/g and C2H5OH concentration of 62%. Moreover, the optimal plant extract exhibits good α-glucosidase inhibition with a half-maximal inhibitory concentration (IC50) of 22.67 mg/mL, compared to the positive control (acarbose −7.77 g/mL). Additionally, P. pulchra is proposed to be a potential antioxidant with an IC50 of ~12.68 µg/mL.Conclusions. The study confirmed the optimal extraction condition of P. pulchra that will obtain the highest total flavonoid content and revealed the potentials of P. pulchra in α-glucosidase inhibition and antioxidation.

On Timor island, Nusa Tenggara Timur, faloak barks (Sterculia quadrifida R.Br.) has been used empirically to restore stamina. Faloak bark ethanolic extract proved to have immunomodulatory activity in vitro, which can increase macrophage phagocytosis activity. This research aimed: (i) to determine the immunomodulatory active fraction of faloak bark ethanolic extract, (ii) to determine the total flavonoid contents of faloak extract and fractions, and (iii) to evaluate the correlation of the total flavonoid contents of those extract and fractions with their macrophage phagocytosis activity. The simplisia powder is macerated with 96% ethanol. The extract was dissolved in methanol:water (9:1v/v) was then subsequently partitioned with n-hexane, ethyl acetate, and water to obtain n-hexane fraction, ethyl acetate fraction, water fraction, and insoluble fraction. Faloak extract and fractions at concentration 62,5; 125; 250; 500μg/mL were tested for their effect on the peritoneal macrophage phagocytosis of Balb/c mice in vitro by the latex beads method. Phagocytosis capacity and phagocytosis index were analyzed using one-way anova and post hoc Tukey HSD test with 95% confidence level. The results showed that ethyl acetate fraction had the highest macrophage phagocytosis capacity and the highest total flavonoid content compared to other fractions. The highest macrophage phagocytosis capacity of ethyl acetate fraction at concentration of 250 μg/mL was 51,94±4,67%, this value was significantly different from cell control (7,50±1,29%), negative controls of 0,0625% dimethylsulphoxide (6,25±0,36%), as well as positive control of 200 μg/mL echinaceae extract syrup® (9,97±0,33%). The total flavonoid content of ethyl acetate fraction determined by aluminum chloride method was 4,290±0.029 mg of quercetin equivalent/g fraction. There was a positive and strong correlation between the total flavonoid content of these extract and fractions with their macrophage phagocytosis capacity (Pearson correlation coefficient of 0,781) and showing linear relationship y=4,721x+19,663; R2=0,61.
