The present investigation was carried out to evaluate the antifungal activities of Phyllanthus polyphyllus L. leaf extract, to isolate its active constituent 4-o-methyl gallic acid (4-o-MGA), and to determine the antioxidant and antiaflatoxigenic properties. The bioassay-guided fractionation of methanol extract led to the isolation of active compound 4-o-methylgallic acid. The methanol extract showed the highest amount of phenolic content (290 mg GAE/g dry extract), which indicated the involvement of phenolic compounds in the radical scavenging activity observed by the methanol extract. The antioxidant capacity of 4-o-MGA was greater than the standard butylated hydroxytoluene, followed by methanol extract. The concentration-dependent growth inhibitory activity was observed against the tested fungi, in which the field fungi were susceptible, while the storage fungi were found to be more resistant including aflatoxigenic A. flavus. A correlation was observed between fungal biomass and aflatoxin production in control and treatment, there was a decrease in biomass of A. flavus and aflatoxin production with increasing concentration. The aflatoxin production was completely inhibited in vitro by methanol extract at 1 mg/mL and 4-o-MGA at 2 mg/mL, but the mycelial growth was not inhibited completely. The inhibition of aflatoxin production was relatively higher than the mycelial growth inhibition of A. flavus, such behaviors might have been determined by the presence of hydrolysable tannin 4-o-MGA in the extract, which is known to inhibit the aflatoxin biosynthesis. The significant antioxidant and aflatoxin inhibitory activities of P. polyphyllus could be exploited for its application in preventing oxidative deterioration and fungal spoilage of food products.

“…Antifungal property of D. hamiltonii root against seed-borne fungi of paddy was found to be similar to that of a synthetic fungicide but with the added advantage of retaining the nutritional properties [40]. The active ingredient responsible for the root's antifungal activity was reported to be HMB [30]. Although Decalepis is a decisively accredited medicinal plant, majority of available reports in this plant pertains to pharmaceutical/nutraceutical value of this plant, in vitro micropropagation and assessing the antibacterial and insecticidal properties.…”

“…The presence of HMB in the extract has been confirmed using thin-layer chromatography, the solvent system being hexane:benzene (1:1); this technique, coupled with observation under short length ultraviolet, has facilitated in determining the presence of this hydroxybenzoate [28]. The identification of this compound, however, has been validated using 13 C nuclear magnetic resonance (NMR), 1 H NMR, infrared spectroscopy, and mass spectroscopy primarily to determine various ionic groups and their arrangements [29,30].…”

Objective: Rich endowment of traditional knowledge plays a critical role in health care, food security, culture, environment and development. Traditional knowledge is also widely used by the aromatic, flavoring, food and health industries. Plant-based traditional medicine has often been used to identify and fast-track the development of modern food and drugs. Plants synthesize such wide array of secondary metabolites that includes alkaloids, glucosinolates, terpenoids and phenylpropanoids. This study is aimed to review on indigenous and exotic medicinal plants containing an astounding food flavoring metabolite; 2-hydroxy-4-methoxybenzaldehyde (HMB). Material and Method:The review focuses on the isomer of vanillin, 2-hydroxy-4-methoxybenzaldehyde, also called MBALD, HMB, or 2H4MB, a flavor compound that is generally found in the roots and rhizomes of medicinal plants. This food flavoring phenylpropenoid is one of the least investigated isomers of vanillin. HMB is known to exhibit a wide array of medicinal properties. Though the molecular role of these metabolites remains largely unknown, they are known to play a key role in plant-environment interactions/stress response/defence signaling and application in pharmaceutical and nutraceutical industries. Discussion and Conclusion:One of the key secondary metabolites is the group of phenylproponoids synthesized either through shikimic acid pathway or the malonate/acetate pathway. Phenylalanine ammonia lyase (PAL) is the enzyme involved in phenylpropanoid pathway catalysing the deamination of phenylalanine to synthesize cinnamic acid that subsequently synthesizes variety of phenylpropanoid products. Inspite of its medicinal importance, the regulatory molecular mechanism underlying the biosynthetic pathway is largely unknown.

“…(Asclepiadaceae), an edible plant (Anon 1952), showed highly significant antifungal activity in vitro, against many phytopathogenic fungi. The active compound responsible for antifungal activity was 2-hydroxy-4-methoxybenzaldehyde (Mohana et al 2008). The present study evaluates a dose dependent antifungal activity of the active compound against important fungal pathogens isolated from paddy and efficacy of the compound on prevention of fungi inducing biodeterioration of paddy grains during storage.…”

Abstract:In vitro antifungal activity assay of different concentrations of 2-hydroxy-4-methoxybenzaldehyde isolated from Decalepis hamiltonii against six important seed-borne fungal pathogens viz., Alternaria alternata, Drechslera tetramera, Fusarium oxysporum, F. proliferatum, Pyricularia oryzae and Trichoconis padwickii isolated from paddy seeds revealed that, the compound 2-hydroxy-4-methoxybenzaldehyde showed significant antifungal activity. Among the fungi tested, F. proliferatum showed highest inhibitory activity, whereas P. oryzae showed least inhibitory activity. The minimal inhibitory concentration (MIC) varied between 350 µg/ml and 650 µg/ml depending on the fungal species. Comparative evaluation of the active compound with the synthetic fungicide thiram at recommended dosage revealed that, the antifungal activity of the active compound obtained from the plant was almost equivalent.Evaluation for nutritional parameters and dry matter losses (DML) revealed that, total carbohydrates, water soluble proteins, lipids and dry matter losses were significantly confined in 2-hydroxy-4-methoxybenzaldehyde treated paddy seeds compared with control seeds. This plant being an edible one can be exploited in the management of seed-borne pathogenic fungi and in the prevention of biodeterioration of grains and mycotoxin production during storage in an eco-friendly way.
