 Objective: The aim was to investigate the physicochemical analysis, preliminary phytochemical screening and further evaluation of its antibacterial activity from morbesi-besi (Tarenna polycarpa) leaf ethyl acetate and hexane fractions (HF).Methods: The physicochemical parameters were carried out as per the World Health Organization (WHO) guideline from its ethanolic extract. The phytochemical screening was performed as per Indonesia Pharmacopoeia and conventional method on its ethyl acetate and HF. Ethyl acetate and HF at different concentration were evaluated using agar well diffusion assay.Result: The plant was found to be free from contaminations. Morbesi-besi leaf fractions are composed of flavonoids, glycosides, saponins, tannins, steroids, and triterpenoids. The phytochemical screening showed only ethyl acetate of lotus leaf extract contains the flavonoids. The antibacterials assay showed that ethyl acetate fraction was better than HF from the inhibition zone.Conclusion: From the outcomes of this study, morbesi-besi leaf (T. polycarpa) possess potential antibacterial activity.

Infection is one of the main causes of world health problems, especially in developing countries like Indonesia, one of which is an acute respiratory infection caused by bacteria such as Staphylococcus aureus. Therapeutics are used for the treatment of infections today with antibiotics. However, there are many cases of bacterial resistance to antibiotics that need to develop alternatives derived from plants. One of the plants that have antibacterial activity is the leaves of Waru Gunung (Hibiscus macrophyllus). The purpose of this study was to determine whether the ethanolic extract of H. macrophyllus leaves and their fractions have antibacterial activity against S. aureus. The method used in this antibacterial activity test is the disk diffusion method with a test concentration of 5%, 10%, 15%, 20%, and 25%. The results of this study indicate that all test samples have antibacterial activity except in the water fraction. The highest antibacterial activity was obtained in the ethyl acetate fraction which attracted semipolar compounds in the ethanolic extract of H. macrophyllus leaves. The antibacterial activity of the test samples in sequence from high to low includes ethyl acetate fraction, ethanolic extract, n-hexane fraction, and water fraction.

Conyza canadensis (L.) Cronquist (CCL) has been used by K’Ho minority in Bidoup Nui Ba national park, Lam Dong province, Vietnam as one of wound healing remedies. However, the scientific proof of treatment is still unclear. This study aimed to evaluate this wound healing potential of CCL. CCL power was extracted by ethanol and then partitioned consecutively with petroleum ether, ethyl acetate and water. Wound healing potential was evaluated by antibacterial activity, stimulation of fibroblast and keratinocyte proliferation. Agar-well diffusion was used in the antibacterial tests and the results showed that CCL had antibacterial activity against 02 dermatitis bacteria (Pseudomonas aeruginosa, Staphylococcus aureus) and 02 opportunistic infection bacteria (Escherichia coli, Enterococcus faecalis). Moreover, our results illustrated that CCL stimulated the fibroblast and keratinocyte proliferation compared to the control. Particularly, the fibroblast division increased 1.6 times at 31.25 µg/mL when treated by ethanolic extract, while ethyl acetate fraction showed 1.7 times increase at 10 µg/mL in keratinocyte proliferation compared to the control. Taken together, our study contributed scientific base of CCL in the wound healing.

Abstract Background: Echinops kebericho is an endemic medicinal plant in Ethiopia traditionally used for treatment of various infectious diseases through different routes of administration such as inhalation, orally chewed, and topically sprayed to affected area. This study investigated antibacterial activity of the essential oil (EO) and the different fractions of ethanolic extract of Echinops kebericho tuber.Results: MIC of EO ranged from 78.125 µg/ml – 625 µg/ml and it was most active against methicillin resistant S. aureus (MRSA, NCTC 12493). Ethyl acetate fraction showed better activity against MRSA (NCTC 12493), MIC = 39.075 µg/ml followed by E. faecalis (ATCC 49532), MIC = 78.125 µg/ml and was least active against K. pneumonia (ATCC 700603), MIC = 1250 µg/ml. MIC of hexane fraction ranged from 156.2- µg/ml to E. faecalis (ATCC 49532) to 1250 µg/ml to E. coli (NCTC 11954). Chloroform fraction MIC ranged from 312.5 - 2500µg/ml; while butanol fraction could be considered pharmacologically inactive as its MIC value is 2500 µg/ml for all and no activity shown for E. coli (NCTC 11954). The MIC of DMSO against all strains ranged 12.5- 25 % w/v. The MIC estimated by OD measurement correlated well with that of resazurin assay method.Conclusion: Essential oil and ethyl acetate fraction showed noteworthy antibacterial activity, and MRSA was the most susceptible strain. Further study, however, should be done to investigate the effect on the isolated active component(s).

Diarrhea is a symptom of a disease, which is characterized by increased frequency of defecation (more than three times a day) with a more fluid of feces. In Ayurvedic medicine, the fruit of Malacca (Phyllanthus emblica L.) is often used as an antibacterial and antiviral against various infectious diseases. This study aims to determine:(i) the antibacterial  activities of ethanol extract and its fraction of Malacca fruit, and (ii) determine Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) against diarrhea-causing bacteria, such as Bacillus cereus FNCC0057 and Shigella dysenteriae ATCC13313. The study was  conducted through several processes: (i) the determination of the plant and  preparation dried fruit, (ii) extraction of dried fruit, fractionated extract, antibacterial activity test of ethanol extract and its fractions, (iii) determination MIC and MBC from the most active fractions and (iv) phytochemical screening of fraction. The results showed that ethanol extract, water fraction and ethyl acetate  fraction of Malacca fruit has antibacterial activities against B. cereus FNCC0057 and S. dysenteriae ATCC13313, where the greatest activity was shown by the fraction of ethyl acetate. This fraction has MIC and MBC values of 0.187 - 0.375% (w/v) and and 0.09375 - 0.1875% (w/v) against B. cereus FNCC0057 and S. dysenteriae ATCC13313. The antibacterial activity of this fraction was probably derived from alkaloid, flavonoid, tannin, quinone, saponin, monoterpene or sesquiterpene compounds.
