“…Accordingly, scientific interest in controlling weeds through allelochemicals has recently increased. Studies have reported that the allelochemical components of some plant species effectively inhibit the germination and growth of weeds, which are effects primarily attributed to the phenolic compounds present in the sample extracts [ 47 , 54 ]. However, no study has yet been conducted to evaluate allelopathic weed management systems for M. sacchariflorus under field conditions.…”

There is increasing interest in the application of bioherbicides because they are less destructive to the global ecosystem than synthetic herbicides. Research has focused on reducing the dependence upon synthetic herbicides by substituting them with environmentally and economically sustainable bioproducts. Allelopathic phytochemicals may be an efficient method for controlling weeds, benefitting both the environment and human health. This study addressed the allelopathic potential of Miscanthus sacchariflorus (MS) extracts on the germination, plant growth, biomass, and biochemical parameters (electrolyte leakage, photosynthetic pigments, and antioxidant enzyme activities) of weeds using laboratory and field experiments. Liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) showed the presence of 22 phenolic compounds, including Orientin, Luteolin, Veratric acid, Chlorogenic acid, Protocatechuic acid, p-Coumaric acid, and Ferulic acid. Leaf extracts of M. sacchariflorus either completely suppressed or partially reduced seed germination and affected the development of weed seedlings (root and shoot length), in a dose-dependent manner. Aqueous extracts of M. sacchariflorus reduced the fresh weight and dry weight, affected the photosynthetic pigment content (chlorophylls, carotenoids), influenced the electrolyte ion leakage, and stimulated the activity of antioxidant enzymes in a species-specific manner. Pearson’s correlation analysis showed that the phenolic compound composition of M. sacchariflorus correlated with the variables tested, indicating that the phytochemicals present in the plant extracts of M. sacchariflorus are a potential source of bio-herbicides.

“…In the same manner, for the control treatment, 100 µL of DMSO was added to sterile water to obtain a final volume of 10 mL (< 1% v/v) because it was used to dissolve the fractions and compound evaluated. All treatments were incubated in the dark at 28 °C in a growth chamber (Lab Line, Ambi 350DT) for 6 days for L. sativa and 10 days for Lolium perenne . At the end of each period, the number of germinated seeds was recorded (those that showed 1 mm of protrusion from the radicle emergence) and the lengths of the root and stem were measured.…”

“…At the end of each period, the number of germinated seeds was recorded (those that showed 1 mm of protrusion from the radicle emergence) and the lengths of the root and stem were measured. Germination percentage and seedling growth effects were calculated for each trial. The experiment included three independent (Petri dish) replicates per treatment in a completely randomized design.…”

BACKGROUND: Within its natural habitat, Croton ehrenbergii exhibits an innate defense mechanism that is not seen in other plants; it grows unharmed amidst predators and nature, while other species perish. In light of its capacity for defense, C. ehrenbergii was evaluated to better understand the scope of its phytotoxic and nematicide properties. To assess this, fractions obtained by bipartition of a hydro-alcoholic extract, and L-quebrachitol, the main constituent of C. ehrenbergii, were evaluated on Lactuca sativa (dicotyledon) and Lolium perenne (monocotyledon) seeds. Additionally, bipartition fractions and L-quebrachitol were evaluated on a population of Meloidogyne incognita for their nematicide activity. RESULTS: From this phytochemical research, L-quebrachitol (1), phenylalanine (2), trans-4-hydroxy-N-methylproline (3) andthe flavonoids: kaempferol (4), tiliroside (5), nicotiflorine (6) and rutin (7) were identified by spectroscopic analysis. Both methanol and hexane fractions from aerial parts of the plant inhibited the germination and elongation of roots and stems in L. sativa, but not in Lolium perenne, showing that these fractions mostly inhibit the dicotyledon species used in this research. L-Quebrachitol showed slightly higher seed germination inhibition for Lolium perenne in comparison with L. sativa. Three of the fractions evaluated showed nematicide activity against Meloidogyne incognita larvae (J2) at the 48 h benchmark, compared with carbofuran. L-Quebrachitol shows higher mortality after 48 h exposure at a lower concentration than carbofuran. genus (4-7), whereas others were not (1-3). This is the first phytochemical, phytotoxic and nematicide report on C. ehrenbergii. Methanol and hexane fractions from the aerial parts of C. ehrenbergii and L-quebrachitol could be used as alternative natural herbicides, predominantly against dicotyledon weed seeds. All fractions had a good mortality percentage against J2 Meloidogyne incognita larvae. CONCLUSION: A variety of compounds were isolated from this research, some were common within the Croton

Objective: This research was study about phytochemical active phenolic compound from pods of jiringa (Archidendron jiringa (Jack) I. C. Nielsen) and it's antioxidant. Methods:Pods of jiringa were air dried and macerated with methanol. Extract was evaporated using rotary evaporator, and then, crude extract dissolved with water and partitioned with ethyl acetate. Extracts were evaporated and partitioned again with methanol and n-hexane. Column and preparative chromatography used to separate pure compound. Pure compound as methyl gallate was identificated with data from nuclear magnetic resonances of proton H ( 1 H NMR), NMR of carbon ( 13 C NMR), and mass spectrometry (MS). Antioxidant activity of pure compound tested by 1,1-diphenyl-2-picrylhydrazyl method. Results:We found pure phenolic compound from pods of jiringa as methyl gallate that exists on fraction III-2, and it has high antioxidant activity with inhibition concentration 50 was 3.7576 µg/ml. Conclusions:Pods of jiringa contain of active phenolic compound as methyl gallate that has high antioxidant activity. Therefore, it can be used as a source of natural antioxidant.
