Medicinal plants such as porang (Amorphophallus muelleri Blume) can produce bioactive compounds from plants-associated endophytes. Therefore, medicinal plants were a sources of isolation of endophytic fungi and endophytic fungi were a sources of secondary metabolites that have anticancer, antimalarial, antimicrobial, and so on. A Porang tuber has been used as a medicine for boils, medicine for sliced wounds and medicine for wounds due to venomous animal bites. The research was aimed to carry out isolation and characterization of endophytic fungi from porang tuber, and to test the ability of endophytic fungi from porang tuber as antibacterial against gram positive (Staphylococcus aureus) and gram negative (Escherichia coli) bacteria. Isolation of endophytic fungi from porang tubers succeeded in getting five different fungi isolates. Based on macroscopic and microscopic characteristics, endophytic fungi isolated from porang tuber were members of the genus Curvularia, Penicillium, 2 isolates of Aspergillus, and 1 isolate that had not been identified. Porang endophytic fungi had antibacterial activity against S. aureus, but did not have antibacterial activity against E. coli bacteria. Endophytic fungi that had antibacterial activity were Curvularia sp., Penicillium sp., Aspergillus sp.

Phytochemical study of two medicinal plants from Ecuador, Tagetes terniflora Kunth, and Croton rivinifolius Kunth, led to the isolation and characterization of the major constituents present in the organic extracts obtained from these plants: 5-(4-acetoxy-1-butynil)-2,2’-bi-thiophene (1), 5-methyl-2,2’:5’,2”- terthiophene (2), patuletin (3) from Tagetes terniflora, and isocorydine (4), sweroside (5), tiliroside (6) from Croton rivinifolius. The structures of these compounds were established by spectroscopic analysis including two-dimensional NMR methods, MS, and comparison with published spectral data. They are recognized as secondary metabolites that represent the chemotaxonomy of Tagetes and Croton genera and could be responsible for the recognized medicinal properties attributed to these species. This paper deals with the first report that shows the presence of these compounds in these plants.

Warburgia ugandensis Sprague is one of the medicinal plants traditionally used to treat a number of diseases like asthma, cough, diarrhea, common cold, stomachache and toothache in Ethiopia. However, there is still insufficient information on the isolation and evaluation of bioactive compounds from this plant species. Extraction, purification and isolation of the stem bark of this plant by dichloromethane and chloroform as solvents afforded two sesquiterpenes; namely, WU-1 (ugandensidial) and WU-2 (cinnamolide-3β-acetate) respectively. The structural elucidations of these bioactive compounds were accomplished by using a variety of spectroscopic methods (IR, UV and NMR). The spectroscopic results compared with the reported data in the literature.

Infectious Origin

abstract Medicinal plants have many traditional claims including the treatment of ailments of infectious origin. In the evaluation of traditional claims, scientific research is extremely important. In this study, five homoisoflavonoids named 3-(4'-hydroxybenzylidene)-5,7-dihydroxy-6-methoxychroman-4-one(Autumnalin),3-(4'-hydroxybenzyl)-5,7-dihydroxy-6-methoxychroman-4-one (3,9-dihydro-autumnalin), 3-(3',4'-dihydroxybenzyl)-5,8-dihydroxy-7-methoxychroman-4-one,3-(3',4'-dihydroxybenzylidene)-5,8-dihydroxy-7-methoxychroman-4-one and 3-(3',4'-dihydroxybenzylidene)-5,7-dihydroxy-6-methoxychroman-4-one, were isolated from the bulbs of the plant Scilla persica HAUSSKN. Their structures were established on the basis of extensive spectroscopic analyses such as NMR, MS, IR and UV.
