“…The ethyl acetate extract was reported to possess some phytotoxic allelochemicals, such as phenolic acids. For example, the ethyl acetate fraction from Tridax procumbens contains phenolic acids such as benzoic acid, vanillin, ferulic acid, and ellagic acid [ 34 ]. These phytochemicals have been reported to inhibit plant growth through several mechanisms, including disrupting photosynthesis and respiration, altering membrane permeability, inhibiting cell division, decreasing enzyme function and activity, and suppressing protein synthesis [ 35 ].…”

Stevia (Stevia rebaudiana), recognized for its low‐calorie, sugar‐free attributes, and various health benefits, has potential applications beyond human consumption, particularly in agriculture. This study explored the potential uses of Stevia in both agricultural and healthcare contexts by examining its plant‐inhibitory, cytotoxic, and antioxidant effects. The methanolic extract of Stevia leaves was fractionated into hexane, ethyl acetate, chloroform, and water fractions. These fractions were then subjected to the bioassay analyses above and underwent identification of their chemical constituents. The results indicated that the ethyl acetate fraction demonstrated significant inhibitory effects on weed germination and growth of Beggars tick (Bidens frondosa) (100% inhibition at 1000 ppm of dose). This fraction also exhibited the highest antioxidant activity, total phenolic, and total flavonoid contents (IC50 DPPH = 18.67 μg/mL, 103.50 mg GAE/g fraction, and 410.16 mg QE/g fraction, respectively). In contrast, the chloroform fraction showed the highest cytotoxic effect (LC50 = 700.01 ppm) in the brine shrimp (Artemia salina) mortality evaluation. Pearson’s correlation analysis revealed a positive correlation among plant inhibitory effects, antioxidant potentials, and phenolic/flavonoid contents of Stevia. FTIR spectra confirmed the presence of phenols and nonpolar components in the ethyl acetate and chloroform fractions. In addition, GC‐MS analysis successfully identified Stevia’s key constituents, including tetracontane, hexadecane, hexadecanoic acid, methyl ester in the ethyl acetate fraction, and spiro [4.5] decan‐7‐one and 6‐hydroxy‐4,4,7a‐trimethyl‐5,6,7,7a‐tetrahydrobenzofuran‐2(4H)‐one in the chloroform fraction. This study underscores the potential of S. rebaudiana as a source of natural antioxidants and herbicides, offering valuable insights into its diverse applications in agriculture.

Phenolic compounds are vital plant allelochemical groups in the ecology, multiple parts of plants contain a variety of phenolic compounds these natural compounds help plants defend themselves against predatory plants. Plants' acetic acid and shikimic metabolic pathways produce phenolic chemicals. Additionally, these compounds exhibit a wide variety of structural forms. In many commercial processes, phenolic compounds are utilized to create chemicals including insecticides, explosives, medicines, and colors. Phenolic chemicals are widely used as herbicides for crop protection in an allelopathic approach., insecticides, and fungicides. They are also employed in the bleaching stage of paper production. The major goal of this evaluation is to draw attention to the ability of phenolic chemicals to allelopathic, which can offer us solutions to a variety of ecological issues, particularly those related to the conservation of the environmentally friendly development of forests, farms, with other alternatives to current synthetic pesticides include bioactive plant secondary metabolites by releasing phytotoxic substances from plant cells.

The study investigated compounds present in the invasive grass Hordeum murinum L. subsp. murinum and tested the allelopathic potential of this plant against common meadow species Festuca rubra L. and Trifolium repens L. Gas chromatography–mass spectrometry (GC–MS) performed separately on the ears and stalks with leaves of wall barley revealed 32 compounds, including secondary metabolites, that may play an important role in allelopathy. Two compounds, N-butylbenzenesulfonamide (NBBS) and diphenylsulfone (DDS), were described for the first time for wall barley and the Poaceae family. The presence of 6,10,14-trimethylpentadecan-2-one (TMP) has also been documented. Aqueous extracts of H. murinum organs (ears and stalks with leaves) at concentrations of 2.5%, 5%, and 7.5% were used to evaluate its allelopathic potential. Compared to the control, all extracts inhibited germination and early growth stages of meadow species. The inhibitory effect was strongest at the highest concentration for both the underground and aboveground parts of the seedlings of the meadow species tested. Comparing the allelopathic effect, Trifolium repens proved to be more sensitive. In light of the results of the study, the removal of wall barley biomass appears to be important for the restoration of habitats where this species occurs due to its allelopathic potential.
