Several species of Rutaceae have been widely used and commercialized in all regions in Indonesia. Some species of Rutaceae are consumed as fresh fruit and traditional medicine for various kinds of diseases, as well as to add aroma to various Indonesian culinary. Since 1959, Eka Karya Bali Botanic Garden (Eka Karya BBG) has successfully collected dozens of Rutaceae species with unknown potential. In addition to reporting the conservation of Rutaceae in Eka Karya BBG, this study aimed to screen the antifungal activity of Rutaceae methanolic extract toward Aspergillus niger, Cladosporium sp., and Fusarium solani. Leaves of 13 species of Rutaceae (Boenninghausenia sp., Citrus aurantifolia, C. maxima, C. medica, Clausena sp., Melicope sp., Micromelum sp., Murraya paniculata, Toddalia sp., Zanthoxylum sp., Z. alatum, Z. limonella, and Z. ovalifolium) were collected, cleaned, air-dried, soaked in methanol for three days, then evaporated using a rotary evaporator to obtain the plant crude extract. The in vitro inhibitory assay was conducted by the diffusion method. As a result, only C. medica, Clausena sp., and Z. limonella exhibited antifungal activity against those tested fungi. Their antifungal activity increased on day 2 post-treatment but slowly decreased on day 3. Thus, the result of this experiment can be used as preliminary data to researchRutaceae plant extracts as an alternative method to control pathogenic fungi. However, further research is needed to maintain and increase its inhibitory effect.

A series of novel 3-aryl-4-hydroxy-2(5H) furanone-acrylate hybrids were designed and synthesized based on the natural butenolides and acrylates scaffolds. The structures of the prepared compounds were characterized by 1H-NMR, 13C-NMR and electrospray ionization mass spectrometry (ESI-MS), and the bioactivity of the target compounds against twelve phytopathogenic fungi was investigated. The preliminary in vitro antifungal activity screening showed that most of the target compounds had moderate inhibition on various pathogenic fungi at the concentration of 100 mg·L−1, and presented broad-spectrum antifungal activities. Further studies also indicated that compounds 7e and 7k still showed some inhibitory activity against Pestallozzia theae, Sclerotinia sclerotiorum and Gibberella zeae on rape plants at lower concentrations, which could be optimized as a secondary lead for further research.

Cryptococcosis is a worldwide disease caused by the etiological agent Cryptococcus neoformans. It affects mainly immunocompromised humans. It is relatively rare in animals only affecting those that have received prolonged antibiotic therapy. The propolis is a resin that can present several biological properties, including antibacterial, antifungal and antiviral activities. The standard strain C. neoformans ATTC 90112 was used to the antifungal evaluation. The tests were realized with propolis ethanol extract (PEE) G12 in concentrations from 0.1 to 1.6 mg mL-1. The evaluation of MIC and MFC were done according to DUARTE (2002)5. The inhibitory effect of PEE G12 on the fungal growing was seen at the concentration of 0.2 mg mL-1 and 1.6 mg mL-1 was considered a fungicidal one.

Background. Echinops kebericho is an endemic medicinal plant in Ethiopia widely used in the treatment of infectious and noninfectious diseases. Essential oils are known for their antibacterial, antifungal, antiviral, insecticidal, and antioxidant properties. This study evaluated the antifungal activity of essential oil from E. kebericho against four common pathogenic fungi and two standard strains. Methods. The essential oil was obtained by hydrodistillation. The antifungal screening was done by agar well diffusion method. Minimal inhibitory concentrations (MICs) were determined by broth microdilution. Minimal fungicidal concentrations (MFCs) were determined by subculturing fungal strains with no visible growth onto a Sabouraud dextrose agar (SDA) plate. Results. Candida albicans and Cryptococcus neoformans were highly sensitive while Aspergillus flavus did not show sensitivity up to 1 mg/ml of essential oil; MICs ranged from 0.083 mg/ml to 0.208 mg/ml. Concentration and fungal species showed significant dose-dependent associations ( p < 0.0001 ) with antifungal activity. The MICs of essential oil were comparable to those of the standard drug (fluconazole) against C. glabrata and C. krusei. The lowest MFC of the essential oil was observed against Candida parapsilosis (0.145 mg/ml) while the highest MFC was against Candida krusei (0.667 mg/ml). Conclusion. Echinops kebericho essential oil showed noteworthy antifungal activity against Cryptococcus neoformans, Candida albicans, and Candida glabrata and could be a potential candidate for further antifungal drug development.

Coccoloba cowellii Britton (Polygonaceae, order Caryophyllales) is an endemic and critically endangered plant species that only grows in the municipality of Camagüey, a province of Cuba. A preliminary investigation of its total methanolic extract led to the discovery of promising antifungal activity. In this study, a bioassay-guided fractionation allowed the isolation of quercetin and four methoxyflavonoids: 3-O-methylquercetin, myricetin 3,3′,4′-trimethyl ether, 6-methoxymyricetin 3,4′-dimethyl ether, and 6-methoxymyricetin 3,3′,4′-trimethyl ether. The leaf extract, fractions, and compounds were tested against various fungi and showed strong in vitro antifungal activity against Cryptococcus neoformans and various Candida spp. with no cytotoxicity (CC50 > 64.0 µg/mL) on MRC-5 SV2 cells, determined by a resazurin assay. A Candida albicans SC5314 antibiofilm assay indicated that the antifungal activity of C. cowellii extracts and constituents is mainly targeted to planktonic cells. The total methanolic extract showed higher and broader activity compared with the fractions and mixture of compounds.

Panchawalkala is one of the ideal herbal combinations in Ayurveda and it has therapeutic properties such as Vranaropana, Shothahara, Graahi and Visarpahara. And also researchers have been proven anthelmintic, antimicrobial, wound healing and anti-inflammatory activities of these plants in combination and individual too. Ghrita (Ghee) is one of the oil preparation made by cow’s milk and it has Balavardhaka, Ojovardhaka, Vayasthapaka, Dhatuposhaka properties and is supreme in Snehana Dravyas. Panchawalkala is widely used in Kwatha and Powder form. Shatadauta Ghrita is the most famous form of the Ghee. The advantages of different innovative preparations are; increased shelf life, ready to use, better acceptability and ease of application. This study was planned to evaluate in-vitro antifungal activity of traditional Panchawalkala Kwatha and innovative Panchawalkala Shatadauta Ghrita (the Ghrita, hundreds times purified by Panchawalkala Kwatha). It was assessed by adopting agar diffusion method. Each agar plate was divided into four equal parts and was cultivated the Candida albicans. Replicator device was used to inoculate multiple specimens on to two parts of three series of plates with respective drugs. Further, responses of organism to the trial drugs were measured and compared with standard drug of Fluconazole (+ve control) and distilled water (-ve control) by using other two parts of the agar plates. All the plates were incubated at 37°C for 24 hours. According to the findings, Panchawalkala Shatadauta Ghrita has an antifungal effect than Panchawalkala Kwatha. Fluconazole is the best antifungal drug among these and distilled water does not have any antifungal action. Hence, it can be concluded that, Panchawalkala Shatadauta Ghrita has antifungal activity rather than Panchawalkala Kwatha but not effective than Fluconazole.

The present study reports the results of gas chromatography-mass spectrometry (GC/MS) analyses of the essential oil from flowering aerial parts of Cotinus coggygria Scoop. (Anacardiaceae), as well as its in vitro antifungal activity against nine plant pathogenic fungi. Moreover, the essential oil was evaluated for its antifungal activity using the agar dilution method, and also MICs (minimum inhibitory concentrations) and MFCs (minimum fungicidal concentrations) were determined. The major compounds identified by GC-MS were limonene (49.2%), (Z)-β-ocimene (13.6%), α-pinene (8.8%) and (E)-β-ocimene (5.9%). The oil showed in vitro antifungal activity against some species of the Fusarium genus, Botrytis cinerea, and Alternaria solani. Our study indicates that the oil of C. coggygria could be used as a control agent for plant pathogenic fungi in natural formulations.
