Urine preparation was carried out by dilution (1:5) with mobile phase and contained a deuteurated internal standard. The LC separation was performed using a C18 column (1.7 μm; 2.1 mm × 100 mm). The mobile phase consisted of formic acid (0.1%) and formic acid (0.1%) in acetonitrile (90:10 v/v), as a starting gradient at flow rate of 0.2 ml/min with total run 7 min. &lt;strong&gt;Results: &lt;/strong&gt;The lower limit of quantification was 40 ng/ml and the linear extended to 20,000 ng/ml. The method has been successfully to be applied in determined of rat urine 3-HPMA. The results showed that the 70% ethanolic extract of seeds can increased the amount of 3-HPMA in rat urine. &lt;strong&gt;Conclusion:&lt;/strong&gt; The 70% ethanolic extract of seeds displayed a potential ameliorating effect against cyclophosphamide side effects.&lt;/p&gt;

The seeds contain around 1.5 mmol of thiol/sulfhydryl compounds per 100 g of dried seeds. The contents of the sulfhydryl compounds can act like glutathione. On the other hand, the intake of a high amount of &lt;em&gt;Leucaena leucocephala &lt;/em&gt;(Lam.) de Wit seeds is limited by mimosine because it can induce toxicity and death in ruminants.&lt;strong&gt; Objective: &lt;/strong&gt;The aim of this study was to determine sulfhydryl compound levels in &lt;em&gt;Leucaena leucocephala&lt;/em&gt; (Lam.) de Wit seeds after the mimosine removal process. &lt;strong&gt;Materials and methods:&lt;/strong&gt; &lt;em&gt;Leucaena leucocephala&lt;/em&gt; (Lam.) de Wit seeds were soaked in aquadest for 24 hours and then dried at 40°C for 86 hours. The dried seeds were macerated at room temperature using 30%, 50%, 70%, and 96% (v/v) of ethanol as the solvent with a 1:10 solvent-to-solid ratio. Levels of dried extract yield were determined for sulfhydryl compounds and mimosine using a spectrophotometer.&lt;strong&gt; Results: &lt;/strong&gt;The 30% ethanol extract without soaking produced the highest levels of extract yield, but 70% ethanol was the most effective solvent for extracting the maximum sulfhydryl and minimum mimosine levels. &lt;strong&gt;Conclusion: &lt;/strong&gt;Ethanol solvent (70%) can be used to extract maximum levels of sulfhydryl compound and minimum levels of mimosine from &lt;em&gt;Leucaena leucocephala &lt;/em&gt;(Lam.) de Wit soaked seeds.&lt;/p&gt;

Previous research reported that binahong leaves have pharmacological activities as antihyperglycemic, antihyperlipidemic, antibacterial, and others. A traditional plant that has proven efficacious needs to be standardized to ensure the quality and its safety. &lt;strong&gt;Objective:&lt;/strong&gt; This study aimed to characteristics of binahong leaves simplicia obtained from Bogor, West Java. &lt;strong&gt;Materials and Methods: &lt;/strong&gt;The crude extract was obtained by the maceration method using 40%, 70%, and 96% ethanol solvent. The selected extract then standardized, which includes macroscopic and microscopic observations and sets the standard parameter values binahong leaf extract. Parameters LCMS to identify active compounds semiquantitatively. &lt;strong&gt;Results: &lt;/strong&gt;The yield of binahong ethanol extract from 40%, 70%, 96% showed a value of 10.9%, 11.4%, and 12.32%, respectively. From these results, 96% ethanol extract has proceeded for standardization. Macroscopic observation results showed that binahong leaves simplicia has a fine and notched form with 5-10 cm long and 3-7 cm diameter. The microscopic binahong leaves contain palisade tissue, parenchymal tissue, chlorophyll grains, rosette Caoxalate crystals, and spiral type. Phytochemical screening of binahong leaves showed the presence of alkaloids, flavonoids, saponins, tannins, steroids, and phenolic compounds.The standardization of binahong leaves ethanol extract down showed a levels of ethanol-soluble extract&amp;gt; 14.8%, water-soluble extract content &amp;gt; 13.5%, drying &amp;lt; 10%, water content &amp;lt; 8.9%, total ash content &amp;lt; 7.2%. LCMS profiles showed that ethanolic extract 40%, 70%, and 96% all contained vitexin at retention time 5.02 minutes, and m/z values 433.1111. &lt;strong&gt;Conclusion: &lt;/strong&gt;96% ethanolic extract of binahong leaves contains vitexin with pharmacognostic parameters carried out following the standards listed in the Indonesian herb pharmacopeia.&lt;/p&gt;

About 90-95% of all diabetes cases were caused by the failure or incapability of insulin target cells to respond to the insulin in normal state. The use of glibenclamide antidiabetic drugs with herbs has been occurred frequently in the community. Vitexin, one of active compounds in binahong (&lt;em&gt;Anredera cordifolia&lt;/em&gt; (Ten.)

This study aimed to determine the molecular docking interaction of glibenclamide and vitexin in binahong leaves against CYP3A4 as antidiabetic drug. &lt;strong&gt;Method: &lt;/strong&gt;Molecular docking methods were carried out using Autodock Vina software and interaction was visualized using discovery studio. &lt;strong&gt;Results: &lt;/strong&gt;The study indicated that the value of glibenclamide complex free energy with CYP3A4 was -3.2 kcal/mol and the stability has increasing to -4.4 kcal/mol after docked with vitexin. The glibenclamide and vitexin complexes had 7 Pi alkyl hydrophobic bonds, 1 hydrocarbon hydrogen bond 1 Pi-cation electrostatic interactions, other interactions between Pi bond and sulfur atoms in cysteine amino acid residues, Pi bond interactions in phenylalamin aromatic groups with electron pairs oxygen atom. &lt;strong&gt;Conclusion: &lt;/strong&gt;This study concluded that vitexin could improve glibenclamide stability.&lt;/p&gt;

The composition and the flow rate of the mobile phase is the optimized parameter. The analytical parameters validated were detection limits, linearity, accuracy and precision. Pineapple water was stored for 8 h at 10ºC and bromelain was determined using the validated HPLC method.&lt;strong&gt; Result: &lt;/strong&gt;The optimum mobile phase composition was methanolwater (70:30) with a flow rate of 1 ml/min. The detector concentration-response was linear with coefficient of determination of 0.993. The accuracy of HPLC method at a recovery of 1 and 2% bromelain was 106.37 ± 1.94% and 98.12 ± 1.29% (n = 5), respectively. The precision, expressed as the coefficients of variation (CV), at 1 and 2% bromelain were 1.83 and 1.32% (n = 5), respectively. Bromelain level at zero time was 81.53%. After storage for 8 h at 10ºC, bromelain levels in pineapple juice appeared to decrease not statistically significant (p &amp;gt; 0.05), with to mean value of 78.46 ± 2.88%. &lt;strong&gt;Conclusion:&lt;/strong&gt; The HPLC method developed was valid to analyze accurately concentrations of bromelain in pineapple water and it can be used to study the shelf life of pineapple water based on bromelain content. The bromelain content in pineapple juice was not statistically significantly different after 8 h storage at 10°C.&lt;/p&gt;

Quantification was achieved using densitometric measurements at 243 nm. The HPLC method involved a 5 &amp;mu;m C18 column and an isocratic solvent using 0.4% formic acid: methanol (12:88) with a flow rate 1 mL minute-&lt;sup&gt;1&lt;/sup&gt;. Quantitation was also achieved with ultraviolet detection at 243 nm based on peak area. All necessary validation tests for both methods were done for their comparison. The results obtained by these two different quantification methods were compared by Tukey&amp;rsquo;s-test. &lt;strong&gt;Results:&lt;/strong&gt; Both assays provided good linearity, accuracy, precision, specificity and limits of detection and quantitation for determination of rubraxanthone in The Stem Bark extract of &lt;em&gt;G. cowa.&lt;/em&gt; &lt;strong&gt;Conclusion:&lt;/strong&gt; Both methods revealed reasonable validation parameters concerning linearity, accuracy, precision, specificity and limits of detection and quantitation. A statistical comparison of the quantitative analysis of rubraxanthone in extract did not show any statistically significant difference between two analysis methods. As both methods were found to be equal, they therefore can be used for the analysis of rubraxanthone in the Stem Bark extract of &lt;em&gt;G. cowa&lt;/em&gt;.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6s</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">s42</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p&gt;&lt;strong&gt;Meri Susanti&lt;sup&gt;1&lt;/sup&gt;, Sanusi Ibrahim&lt;sup&gt;2&lt;/sup&gt;, Yahdiana Harahap&lt;sup&gt;3&lt;/sup&gt;, Dachriyanus&lt;sup&gt;1,&lt;/sup&gt;*&lt;/strong&gt;&lt;/p&gt;
