Indole Alkaloid

A new, weakly antibacterial indole alkaloid, named lombine, together with the known alkaloid voacangine, have been isolated from the bark of Voacanga foetida (Bl.) Rolfe (Apocynaceae), a plant used on Lombok, Indonesia, for medicinal purposes. A combined chemo- and bio-rational strategy was developed to target this plant for investigation. Lombine was shown to be bactericidal against Staphylococcus aureus and Escherichia coli.

Abstract. Gloria RY, Yuliyani R, Asror MMS. 2021. Effectiveness of green betel leaf and lime extract against Staphylococcus aureus and Escherichia coli. Biodiversitas 22: 3452-3457. Indonesian society utilizes biodiversity as source of medicinal herbs. Betel leaf and lime are included in traditional Indonesian medicinal plants that have antibacterial and antioxidant properties. One of the benefits of herbal medicinal plants of betel leaf and lime is that it can be used as a natural hand sanitizer. The purpose of this study was to test the effectiveness of naturally made hand sanitizer against Staphylococcus aureus and Escherichia coli by the combination of green betel leaf extract and lime extract. The experiment was performed by the Kirby-Bauer disc diffusion method. Results showed that a combination of 50% betel leaf extract and 50% lime extract inhibited the growth of S. aureus whereas, 75% betel leaf extract and 100% lime extract exhibited strong inhibition than 70% alcohol.

ABSTRACT One of the potential medicinal plants as traditional medicine is gardenia plant (Gardenia augusta). Gardenia leaf extract contains alkaloid compounds, flavonoids, tannins, saponins and triterpenoids, which are known to have antibacterial abilities..The aim of this research was to determine the antibacterial activity of gardenia leaf extract on the growth of Staphylococcus aureus, Escherichia coli and Salmonella thypi. The examination on the inhibitory power using the Kirby-Bauer method. The Kirby-Bauer method is referring to the diffusion method using paper disc with five treatments, namely the extract of gardenia leaves with a substance concentration of 20%, 40%, and 60% as well positive control (Ciprofloxacin) and negative control (aquades). Based on the research results obtained, it can be concluded that gardenia leaf extract can inhibit growth of Staphylococcus aureus, Escherichia coli and Salmonella thypi at a concentration of 20%, 40% and 60% and classified as strong and medium category.

Centella asiatica contains some secondary metabolic compounds, e.g. tannin, alkaloid, flavonoid, saponin, and triterpenoid, known as medicinal plants as well, one of which is as a anti-bacterial. The present study aimed at examining the activities of Centella asiatica extract towards the growth of Staphylococcus aureus and Escherichia coli. The extraction of C. asiatica was done by using ethanol and ethyl acetate solvents and the activity test employed seaweed diffusion. The hindrance power of Centella asiatica extract was tested in 30%, 50%, and 95% and the data were analyzed qualitatively with the standard issued by the Clinical and Laboratory Standard Institute and quantitatively with ANOVA. It shows that Centella asiatica extract in the ethyl acetate can hinder the growth of Staphylococcus aureus in the acetate concentration of 50% and 70% at the sensitive level and Escherichia coli at the intermediate level in the extract concentration of 50% and 70%. However, Centella asiatica activities in the ethanol solvent hinders the growth of either Centella asiatica or Escherichia coli with resistant category in the extract concentration of 70%. The hindrance power of Centella asiatica extract in ethyl acetate in the growth of Staphylococcus aureus is significantly more effective than that of Centella asiatica extract in the ethanol solvent

Abstract Background Patients with lymphoedema are at high risk of getting bacterial and fungal wound infections leading to acute inflammatory episodes associated with cellulitis and erysipelas. In Ethiopia, wound infections are traditionally treated with medicinal plants. Methods Agar well diffusion and colorimetric microdilution methods were used to determine the antibacterial activity of methanol extracts of the three medicinal plants against Staphylococcus aureus, Streptococcus pyogenes, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Shewanella alage, methicillin-resistant S. aureus ATCC®43300TM, Staphylococcus aureus ATCC25923, Escherichia coli ATCC25922, Klebsiella pneumoniae ATCC700603, and Pseudomonas aeruginosa ATCC37853. Results The methanol extract of L. inermis leaves showed high activity against all tested bacterial species, which was comparable to the standard drugs. Similarly, the extracts of A. indica showed activity against all tested species though at higher concentrations, and higher activity was recorded against Streptococcus pyogenes isolates at all concentrations. However, the extract of A. aspera showed the lowest activity against all tested species except Streptococcus pyogenes isolates. The lowest minimum inhibitory concentration (MIC) was recorded with the extract of L. inermis against E. coli isolate and S. aureus ATCC 25923. Conclusion Methanol extracts of L. inermis, A. indica, and A. aspera leaves exhibited antimicrobial activity against selected bacterial isolates involved in wound infections, of which the methanol extracts of L. inermis exhibited the highest activity. The results of the present study support the traditional use of plants against microbial infections, which could potentially be exploited for the treatment of wound infections associated with lymphoedema.

Cordia Myxa

Abstract Cordia myxa is considered as one of traditional medicinal plants abundant in many countries including Iraq. Because of the healthy importance of this plant therefore the current research was established to extract the alkaloids from the its leaves with extraction percentage equal to 5.8% Preliminary qualitative detections were achieved for the alkaloids by using various chemical reagents. The medicinal efficacy of these alkaloids was determined depending on maximum inhibitory concentration (Max IC) which has value equal to 150 mg/ml and this concentration recorded inhibition zone diameters values equal to 30,22,26,25 and 30 mm against Staphylococcus aureus, Escherichia coli, Pseudomonas aeroginosa, Proteus Sp. and klebsiella Sp. bacteria. So Cordia myxa leaves alkaloids can be used as natural chemical drug to treat the most infections and inflammatory caused by these pathogens.
