Cassava is one of the most widely produced agricultural products in Indonesia with cassava peel waste of 20%. Cassava peel contains carbohydrates and stores a high cellulose content so that it has a potential to be a bioethanol. This study aims to utilize cassava peel waste for bioethanol production with an alkaline pretreatment process, cellulase enzyme hydrolysis and fermentation by using Zymomonas mobilis bacteria. Alkaline pretreatment with 14% NaOH is used to hydrolyze lignocellulose. The hydrolysis optimization process enzymatically applies the Surface Response Method (RSM) to determine the optimum conditions at hydrolysis pH in the range of 2-10 and hydrolysis temperature in the range of 30-70 °C by analyzing glucose levels using the Dinitrosalicylic Acid (DNS) method and UVvis spectrophotometry instruments. Surface Response Method (RSM) is likewise implemented to decide the greatest conditions of the fermentation process. The pH measurement ranges 2-10, and fermentation time takes 6 to 168 hours. Based on the results of research, it results a lignin content of 6.68% (b/b), cellulose content of 58.4% (b/b), and hemicellulose content of 27.3% (b/b). The optimum conditions of the hydrolysis process obtained an optimum glucose level of 9.22mg/mL at pH 2 and a hydrolysis temperature of 50°C. The optimum conditions of the fermentation process use Zymomonas mobilis at pH 6 while fermentation time takes 168 hours analyzed using a refractometer produced a bioethanol content of 37.75% (v/v) and a gas chromatography produced a bioethanol content of 54.94% (v/v).
木薯是印度尼西亚最广泛生产的农产品之一,木薯皮浪费占20%。木薯皮含有碳水化合物和高纤维素含量,因此它有可能成为生物乙醇。本研究旨在利用木薯果皮废弃物,通过碱预处理、纤维素酶水解和活动单胞菌发酵生产生物乙醇。采用14% NaOH碱性预处理水解木质纤维素。利用二硝基水杨酸法(DNS)和紫外分光光度仪对葡萄糖水平进行分析,确定水解pH为2 ~ 10,水解温度为30 ~ 70℃的最佳条件。采用表面响应法(RSM)确定发酵过程的最佳条件。pH值测量范围为2-10,发酵时间为6 - 168小时。研究结果表明,木质素含量为6.68% (b/b),纤维素含量为58.4% (b/b),半纤维素含量为27.3% (b/b)。最佳水解条件为:pH为2,水解温度为50℃,葡萄糖浓度为9.22mg/mL。最佳发酵条件为pH为6的活动单胞菌,发酵时间为168 h,折光仪分析所得生物乙醇含量为37.75% (v/v),气相色谱分析所得生物乙醇含量为54.94% (v/v)。

Diabetes Mellitus (DM) is one of a group of metabolic diseases characterized by hyperglycemia caused by a disturbance in insulin so that blood glucose levels increase. Prevention of absorption of blood glucose by the intestine can be done with the help of the enzyme α-glucosidase. Based on the results of phytochemical tests, it is known that the methanol fraction of sungkai leaves contains flavonoid compounds. The Fourier Transform Infra-Red (FTIR) spectrum showed that the isolates had phenolic O-H groups (3,354.53 cm1 , 1,359.28 cm-1 ), aromatic C=C group (1,615.48 cm-1 ), C-O-C ether group (1,046.60 cm-1 ) and aromatic C-H group (822.21 cm-1 ). In vivo antidiabetic activity test was carried out using test animals of white male mice which were induced by alloxan. Antidiabetic testing was carried out using 6 treatment groups with glibenclamide, Na-Carboxymethyl cellulose (NaCMC) 0.5%, dose 175 mg/kgBW, 350 mg/kgBW, 700 mg/kg Body Weight (BW) and isolates 2 mg/kgBW. The results showed that the methanol fraction of sungkai leaves had the best antidiabetic activity at a dose of isolate and 700 mg/kgBW which was able to reduce blood glucose levels by 42.20% and 42.00%. In vitro antidiabetic testing through αglucosidase enzyme inhibition mechanism did not show any antidiabetic activity at concentrations of fractions 5, 10, 25, 50 and 100 ppm.
糖尿病(DM)是一种以胰岛素紊乱引起高血糖为特征的代谢性疾病,使血糖水平升高。在α-葡萄糖苷酶的帮助下,可以防止肠道吸收血糖。根据植物化学试验的结果,我们知道sunkai叶的甲醇部分含有类黄酮化合物。傅里叶变换红外光谱(FTIR)表明,分离物具有酚类O-H基团(3,354.53 cm-1、1,359.28 cm-1)、芳香C=C基团(1,615.48 cm-1)、C- o -C醚基团(1,046.60 cm-1)和芳香C- h基团(822.21 cm-1)。以四氧嘧啶诱导的白鼠为实验动物,进行了体内抗糖尿病活性试验。采用格列本脲、0.5%羧甲基纤维素钠(NaCMC),剂量175 mg/kgBW、350 mg/kgBW、700 mg/kg体重(BW)和分离物2 mg/kgBW 6个治疗组进行降糖试验。结果表明,松开叶甲醇部位在分离剂量和700 mg/kgBW时的抗糖尿病活性最好,可分别降低血糖42.20%和42.00%。5、10、25、50和100 ppm的α葡萄糖苷酶抑制机制对体外降糖试验无明显作用。

Rourea coccinea is widely used as a medicinal plant in the world, especially in West Africa. The phytochemical screening of ethanolic extract of leaves by applying the Houghton and Raman method with some modifications revealed the presence of alkaloids, phenolic compounds, terpenoids, tannins, coumarins, anthocyanins and anthraquinones. The antiradical test was performed using DPPH (2,2-diphenyl-1-picryhydrazyl), ABTS (2,2-azino-bis (3-ethylbenzo-thiazoline-6-sulfonic acid) diammonium salt) and FRAP (Ferric Reducing Antioxidant Power) with a Scavenging concentration 50 (SC50) of 101.19 µg/mL, 34.73 µg/mL and 88.93 µg/mL respectively. The extract anti-shigella activity determined by the microdilution method was low. According to Jair Siquera-Neto et al., the antileishmanial study using the colorimetric resealing method showed activity against promastigote strains of Leishmania donovani with an inhibitory concentration of IC50=32.26 µg/mL. The traditional use of Rourea coccinea, to treat several diseases, would be justified by these pharmacological property's tests.
在世界范围内,特别是西非地区,Rourea coccinea是一种广泛使用的药用植物。利用霍顿法和拉曼法对叶乙醇提取物进行植物化学筛选,发现其中含有生物碱、酚类化合物、萜类、单宁、香豆素、花青素和蒽醌类化合物。采用DPPH(2,2-二苯基-1-苦基肼基)、ABTS(2,2-氮基-二(3-乙基苯并噻唑-6-磺酸)二铵盐)和FRAP(铁还原抗氧化能力)进行抗自由基试验,其清除浓度50 (SC50)分别为101.19µg/mL、34.73µg/mL和88.93µg/mL。微量稀释法测定的提取液抗志贺氏菌活性较低。Jair Siquera-Neto等人采用比色重封法对多诺瓦利什曼原虫原鞭毛菌进行抗利什曼原虫研究,抑菌浓度为IC50=32.26µg/mL。这些药理学性质的试验证明,球菌Rourea coccinea的传统用途是治疗几种疾病的。

The development of techniques for detecting halal and non-halal animal meat is of great importance as a useful tool for monitoring and assuring food quality for Muslim. Flavor or aroma is one of the sensory attributes for consumers to distinguish broth cattle. The differences aroma of broth cattle is contributed by the content of volatile compounds. This study was aimed to determine the composition of volatile compounds in meat and bone broth from five different animals, i.e., cow (beef), pig (pork), goat, lamb, and chicken for initial identification of halal and non halal food. A preliminary test for samples of meat and bone broth was done by identifying their physical properties including pH, viscosity, and density. The volatile compounds in meat and broth samples were extracted using a solid phase-micro extraction (SPME) at room temperature and analyzed by gas chromatography-mass spectrometry (GCMS). The results revealed the physical properties of meat and bone broth, i.e., pH, viscosity, and density, cannot be used to distinguish the type of broth produced from beef, pork, goat, lamb, and chicken. Successful results for the identification were achieved through chromatogram profile of volatile compounds from meat and bone broth which show characteristics to each type of animal, and therefore it can be used to distinguish pork from beef, goat, lamb, and chicken as initial detection for halal and non halal food. The research also identified 7 predominant volatile compounds as a marker for meat pork and other 8 specific compounds marker for pork bone.
清真和非清真动物肉类检测技术的发展作为监测和保证穆斯林食品质量的有用工具具有重要意义。风味或香气是消费者区分肉汤牛的感官属性之一。肉汤牛香气的差异是由挥发性化合物的含量决定的。本研究旨在测定五种不同动物的肉和骨汤中挥发性化合物的组成,即牛(牛肉)、猪(猪肉)、山羊、羊肉和鸡肉,以初步鉴别清真和非清真食品。对肉和骨汤样品进行了初步测试,确定了它们的物理性质,包括pH值、粘度和密度。采用固相微萃取法(SPME)提取肉类和肉汤样品中的挥发性化合物,并采用气相色谱-质谱联用技术(GCMS)进行分析。结果表明,肉汤和骨汤的物理性质,即pH值、粘度和密度,不能用于区分牛肉、猪肉、山羊、羊肉和鸡肉生产的肉汤的类型。通过对肉和骨汤中挥发性化合物的色谱谱分析,获得了鉴定的成功结果,显示了每种动物的特征,因此它可以用于区分猪肉与牛肉、山羊、羊肉和鸡肉,作为清真和非清真食品的初步检测。研究还鉴定出7种主要挥发性化合物作为肉猪的标记物,以及8种特异性化合物作为猪骨的标记物。

Diabetes mellitus causes a pancreatic β-cells damage due to the increase of oxidative stress, thereby reducing Superoxide Dismutase 1 (SOD1) activity. This enzyme activity can be increased by utilizing antioxidant compounds from the avocado seed extract. This study aims to determine the increase of SOD1 expression and the repair of pancreatic β-cells tretaed with the ethanol extract of avocado seeds (Persea americana Mill). It is also aimed to observe the expression of pancreatic SOD1 and its histopathology change. The expression was measured by using immunohistochemical. This research used 20 Wistar rats aged of 2-3 moths, weighing of 150-200 grams. The diabetic rats were induced by streptozotocin (STZ) with dose of 30 mg/kg BW intraperitoneally. The rats were divided into 5 groups, namely: group 1 is healthy rats, group 2 is diabetic rats, while the group 3, 4 and 5 are therapeutic groups with 300, 350 and 400 mg/kg BW doses of ethanol extract for 14 days treatment. The results showed the ethanolic extract of avocado seeds has a potential as an antidiabetic agents based on the increase of pancreatic SOD1 (p<0.05) significantly, increase of SOD1 expression 7.6 ± 1.34, 11.6 ± 1.94 and 13.0 ± 2.82 in three different doses therapy (300, 350 and 400 mg/kg BW), and repairing structure of β-pancreatic cells on the therapeutic groups.

Nanostructured Lipid Carriers (NLC) are lipid-based carrier that uses a combination of liquid and solid lipids which is believed to deliver a higher amount of active substance to the human body. This study aimed to obtain the best formulation and evaluate the stability of curcuminloaded NLC (C-NLC) using microfluidic technique at temperature of 40o C and 60o C with the ratios of liquid:solid lipids were 2 : 1 ; 3.5 : 1 ; 4 : 1 ; 6 : 1% w/w. Our results showed that the increase of process temperature and liquid lipid concentration reduced particle size. There was a non-linear relationship between lipid ratio and temperature to encapsulation percentage. At ratio of soybean oil:stearic acid 6 : 1 and, at 40°C, particles size (PS) obtained was 143.87 ± 3.36 nm, polydispersity index (PDI) obtained was 0.44 ± 0.01, zeta potential (ZP) obtained was -33.3 ± 6.53 mV with encapsulation percentage of 20.62%. At the same ratio at 60°C, the PS obtained was 60.21 ± 2.55 nm, PDI obtained was 0.72 ± 0.03, ZP obtained was -26.10 ± 1.83 mV and encapsulation percentage of 31.45%. Stability test showed that C-NLC produced at 60°C was more stable since the change of particle size and pH were lower than C-NLC produced at 40°C.
纳米结构脂质载体(NLC)是一种基于脂质的载体,它使用液体和固体脂质的组合,被认为可以向人体输送更多的活性物质。本研究以姜黄素负载NLC (C-NLC)为研究对象,在液固比为2:1、温度为400℃和600℃时,采用微流控技术优选其最佳配方,并评价其稳定性;3.5: 1;4: 1;6: 1% w/w。实验结果表明,工艺温度的升高和液脂浓度的升高使颗粒尺寸减小。脂质比与温度对包封率的影响呈非线性关系。在40℃条件下,豆油与硬脂酸的比例为6:1,得到的颗粒尺寸(PS)为143.87±3.36 nm,多分散指数(PDI)为0.44±0.01,ζ电位(ZP)为-33.3±6.53 mV,包封率为20.62%。在相同配比下,在60℃条件下,得到的PS为60.21±2.55 nm, PDI为0.72±0.03,ZP为-26.10±1.83 mV,包封率为31.45%。稳定性测试表明,在60°C条件下生产的C- nlc比在40°C条件下生产的C- nlc更稳定,因为粒径和pH的变化都更小。

Breast cancer is a condition where the cells in breast tissue lose control and multiply uncontrollably. In this study, MCF-7 breast cancer cells were tested for cytotoxic activity using the MTT assay and the active compound's interaction with the p53 protein was tested in silico. The most active fraction was found to be the ethyl acetate fraction, with an IC50 value of 1.730 μg/mL and a selectivity index of 2.485. However, the selectivity index was less than 3, and Vero cells showed changes in morphology with the addition of the ethyl acetate fraction. GC-MS was used to identify 19 compounds in the ethyl acetate fraction, and in-silico tests were performed on 5 potential anticancer compounds. Lipinski's Rule of Five test showed that only 3 of these compounds could undergo molecular docking. The results indicated that Anethole compound can interact with p53 protein, while Cinnamaldehyde, (E)- can interact with p21 protein.

High ionic conductivity and porous properties of material play important role as a solid polymer electrolyte in Li ion battery application. In this study, a bacterial cellulose (BC)- based polymer was modified with polyvinyl pyrrolidone (PVP) and polyvinyl alcohol (PVA). Blending the polymer host is one more approach to work on the morphology pore and electrochemical properties of polymer electrolytes. The slurry of BC is rich of fibers that contribute to forming of the pore template for solid electrolyte membrane. Polyvinyl act as material to creating pore and increases the polymer segmental ion lithium mobility. Pore morphology of BC-PVA and -PVP composite membrane homogeneously distributed by SEM observations. The presence of many pores makes the tensile strength of the BC PVA membrane lower. For solid electrolytes purposes, it does not affect battery performance but has a greater possibility for battery lifetime. The presence of pores contributes to the absorption of electrolytes membranes. In addition, enhancement of the conductivity upon addition of salt is correlated to the enhancement of pores from solid polymer electrolyte. The conductivity of BC-PVA composite is reported 8.7 x 10-5 Scm-1 , and this ion conductivity is slightly higher than conductivity in BC-PVP 8.4 x 10-7 Scm-1 at room temperature. In the future, BC-PVA can be applied for solid electrolyte membranes material based on cellulose.
材料的高离子电导率和多孔性在锂离子电池中作为固体聚合物电解质发挥着重要的作用。本研究以聚乙烯吡咯烷酮(PVP)和聚乙烯醇(PVA)对细菌纤维素(BC)基聚合物进行改性。混合聚合物主体是研究聚合物电解质形态、孔隙和电化学性能的又一途径。BC浆液中含有丰富的纤维,有助于形成固体电解质膜孔模板。聚氯乙烯作为材料形成孔隙,增加聚合物段离子锂的迁移率。SEM观察BC-PVA和-PVP复合膜的孔隙形态分布均匀。孔隙的存在使BC PVA膜的抗拉强度降低。对于固体电解质,它不影响电池性能,但对电池寿命有更大的可能性。孔隙的存在有助于电解质膜的吸收。此外,加入盐后电导率的增强与固体聚合物电解质孔隙的增强有关。BC-PVA复合材料的电导率为8.7 × 10-5 cm-1,室温下离子电导率略高于BC-PVP的8.4 × 10-7 cm-1。BC-PVA可用于纤维素基固体电解质膜材料。
