“…A total of four compounds were detected in the GC-MS analysis of the chloroform extract of S. alba mangrove leaves, namely mesitylene, benzene-1,2,4-trimethyl, benzene-1-ethyl-3-methyl, and benzene-1-ethyl-2-methyl. Among those compounds, benzene-1-ethyl-3-methyl is known to have antifungal and antibacterial properties [28], while benzene-1,2,4-trimethyl may have potential as an anthelmintic [29]. However, their antioxidant activities are still unknown.…”

The increasing prevalence of oxidative stress-related diseases triggers exploration of new antioxidant compounds. Among natural resources, mangrove trees are prominent producer of unique secondary metabolites. This research was designed to determine phytochemicals and antioxidant activity of Sonneratia alba mangrove leaves extract from Ngurah Rai Mangrove Forest, Bali. The study comprises experimental trials with post-test only control group design. Fresh leaves collected from five different S. alba plants were washed, dried, and grinded into powder. One-hundred gram of dried leaves powder was macerated with 500 mL of chloroform for 2x24 hours. The crude extract was analysed for its antioxidant activity based on DPPH assay. While, phytochemical analysis was evaluated using qualitative approaches and GC-MS method. The chloroform extract showed very strong antioxidant activity with IC50 of 15.59±0.78 ppm. Phytochemical analysis displayed that the extract contains tannin, phenol, and steroid, which explain its antioxidant properties. Furthermore, GC-MS analysis showed that this extract consists of four compounds, namely mesitylene, benzene-1,2,4-trimethyl, benzene-1-ethyl-3-methyl, and benzene-1-ethyl-2-methyl. In conclusion, these results present promising antioxidant activity of chloroform extract of S. alba mangrove leaves from Ngurah Rai Mangrove Forest, Bali. Further research is required to isolate and to purify the specific antioxidant bioactive for therapeutic purposes.

“…56,68,[76][77][78][79] In some cases, several extractions are carried out using successively hexane, chloroform, ethyl acetate and butanol due to their increasing polarity, to explore the widest diversity of metabolites. 70,76,80,81 This strategy allows a finer characterization of the metabolites because each fraction can be analyzed. Thus, among the various secondary metabolites extracted from strains of Alternaria brassicicola and A. gaisen, those present in the hexane fraction had the best efficacy in inhibiting seed germination of Parthenium hysterophorus.…”

Among the alternatives to synthetic plant protection products, biocontrol appears as a promising method. This review reports on the diversity of fungal secondary metabolites phytotoxic to weeds and on the approach generally used to extract, characterize, identify and exploit them for weed management. The 183 phytotoxic fungal secondary metabolites discussed in this review fall into five main classes of molecules: 61 polyketides, 53 terpenoids, 36 nitrogenous metabolites, 18 phenols and phenolic acids, and 15 miscellaneous. They are mainly produced by the genera Drechslera, Fusarium and Alternaria. The phytotoxic effects, more often described by the symptoms they produce on plants than by their mode of action, range from inhibition of germination to inhibition of root and vegetative growth, including tissue and organ alterations. The biochemical characterization of fungal secondary metabolites requires expertise and tools to carry out fungal cultivation and metabolite extraction, phytotoxicity tests, purification and fractionation of the extracts, and chemical identification procedures. Phytotoxicity tests are mainly carried out under controlled laboratory conditions (not always on whole plants), while effectiveness against targeted weeds and environmental impacts must be assessed in greenhouses and open fields. These steps are necessary for the formulation of effective, environment‐friendly fungal secondary metabolites‐derived bioherbicides using new technologies such as nanomaterials.This article is protected by copyright.
