Siamese pumpkin leaves are one of the plants that have antibacterial properties. Compounds that act as antibacterial are flavonoite, tannin, triterpenes, alkaloids, and saponins. The aim of this study was to prove the antibacterial activity of ethanol hexane and chloroform fraction of pumpkin siam leaves and characterize the functional groups of active compounds from pumpkin siam leaves (Sechium edule (jacq). SW) with FTIR spectrophotometers. The extraction process of Siamese Pumpkin leaves was carried out by maceration method using 70% ethanol. The extract was continued with the fractionation process with ethanol, n-hexane and chloroform solvents. Antibacterial activity testing using the well method with a concentration of 100%, positive control chlorhexidi and negative control aquadst. The compound content test used the Thin Layer Chromatography (TLC) method with the stationary phase using silica plate G60 F254 and comparison of the mobile phase of chloroform: methanol: water (2: 5: 3) (v / v). Bioautography test using the contact method, namely the elution TLC plate, was placed on the NA medium containing a bacterial suspension for 3 hours. Antibacterial test results The largest ethanol fraction of pumpkin leaves was at a concentration of 100% with a diameter of inhibition zone of 11.49 mm on P. gingivalis while 16.04 mm in S. mutans. The results of TLC showed the presence of flavonoids with a price of Rf 0.47 and tannin with a price of Rf 0.84. Bioautography results showed a inhibition zone with a price of Rf 0.49 in the bacteria P. gingivalis and S. mutans which are flavonoid compounds. Characterization by FTIR spectrophotometer O-H phenol, C = C aromatic, C-O-C ether, aromatic C-H functional group Keywords: (Sechium edule (jacq) .SW).

Androgenic alopecia (AA) is a condition that most commonly affects adult men and is caused by an increase in the hormone dihydrotestosterone (DHT) in the hair follicles. Anti-alopecia drugs should be discovered for hair follicles to enter the anagen growth phase. Therefore, this study evaluated the hair growth-promoting activity of Noni fruit’s water, ethyl acetate, n-hexane fractions, and sub-fractions from the active fraction in the alopecia male white rabbit model. The Matias method was modified by inducing rabbits using DHT for 17 days, followed by topical application of Noni fruit solution for 21 days. Meanwhile, hair growth was evaluated by histological observation of the follicular density and the anagen/telogen (A/T) ratio in skin tissue. In the first stage, five groups of male white rabbits were studied to obtain the active fraction; DHT+Minoxidil as standard, DHT+vehicle (NaCMC 1%), DHT+FW, DHT+FEA, and DHT+FH. The FEA as the active fraction was followed by open-column chromatography separation (DCM:Methanol) with a gradient of 10% to produce sub-fractions. In the second stage, the six main sub-fraction groups of male rabbits studied were DHT+FEA-1 to DHT+FEA-6. The follicular density of groups FEA-3 was 78.00 ± 1.52 compared with 31.55 ± 1.64 and 80.12 ± 1.02 in the Vehicle and Minoxidil groups. Additionally, group FEA-3 showed large numbers of anagen follicles with an A/T ratio of 1.64/1 compared to the vehicle group of 1/1.50 and 1.39/1 for Minoxidil control. Group FEA-3 was identified by LC-MS/MS-QTOF, followed by molecular docking to the androgen receptor (PDB: 4K7A), causing alopecia. The results showed that three alkaloid compounds with skeleton piperazine and piperidine, namely (compounds 2 (−4.99 Kcal/mol), 3 (−4.60 Kcal/mol), and 4 (−4.57 Kcal/mol)) had a binding affinity similar to Minoxidil, with also has alkaloid skeleton piperidine–pyrimidine (−4.83 Kcal/mol). The dynamic behavior showed the stability of all androgen receptor compounds with good RMSD, SMSF, and SASA values after being studied with 100 ns molecular dynamics (MD) simulations. This study produced a common thread in discovering a class of alkaloid compounds as inhibitors of androgen receptors that cause alopecia.
Corn silk (Zea mayz L.) were empirically used by the community in some regions as traditional remedies for hypertension,kidney stones,diabetes mellitus, urinary tractinfections and gout. This study aimed to determine the effect of corn silk ethanol fraction on decrease uric acid levels in male white mice.corn silk were extracted by macerate used 70% ethanol for 4 days.Urin acid test was performed on male mice induced by beef liver for 7 days.25 mice were grouped into 5 groups, groups dose I, II and III weregiven a fraction at a dose of 27.5 mg / bwBB, 55 mg / bwBB and 110 mg / bwBB, control given Na.CMC 0.5% and as positive controls were given allopurinol dose of 13 mg / bwBB. The five groups were treated orally 1 time a day for 7 days. Decreased uric acid levels were measured and observed on days 7 using an acid (easy touch). The results of ANOVA statistical analysis showed that negative controls gave a significant difference with positive controls, dose I, II and III because the sig value was
Lemongrass (Cymbopogon nardus L. Rendle) and green betel (Piper betle L.) plants are native to Indonesia. Empirically betel leaf can be used as a wound healer, lemongrass leaves are widely used as medicine for insect bites. On the basis of information obtained from various literatures, in this research has been done formulation of ointment from extract combination of lemongrass, green betel leaf and natural zeolite as antibacterial of Staphylococcus aureus. The use of zeolites based on features has a three-dimensional framework structure that is interconnected so that it has a large surface. Based on these reasons, it is believed that zeolites can increase the activity of active substances in ointments. The formulation of ointment extracts of lemongrass leaves-green betel leaves and zeolites with various dosages are KZ (zeolite control), KE (20% -5%), F1 (10% -6% + zeolite), F2 (20% - 5% + zeolite), F3 (30% -4% + zeolite), F4 (20% -0% + zeolite), F5 (0% -5% + zeolite) with a fixed amount of zeolite (2 gr). Evaluation of ointment preparations including organoleptic test, pH, homogeneity, spreading test and adhesion test showed results that met the requirements. The sample was tested for antibacterial activity with positive control (gentamicin 0.1%) showed that all formulas can provide an inhibition zone against staphylococcus aureus, except KZ. Test results were analyzed using One Way Annova with sig (0,000) <p value (0,050) followed by Tukey's further tests. From this explanation it can be concluded that the formulation of ointment from extract combination of lemongrass leaves, green betel leaves and zeolites has antibacterial agent.
