“…In addition, the results indicate that seedling length varied among the model plants, and the level of inhibition depended on the extract concentration (Figure 1). Similarly, several previous studies have also reported that the phytotoxic effect is concentration-dependent [48][49][50][51][52][53]. Moreover, many previous studies noted that test plant speciesʹ response varied depending on the types of phytotoxic substances [54].…”

Phytotoxic substances released from plants are considered eco-friendly alternatives for controlling weeds in agricultural production. In this study, the leaves of Afzelia xylocarpa (Kurz) Craib. were investigated for biological activity, and their active substances were determined. Extracts of A. xylocarpa leaf exhibited concentration-dependent phytotoxic activity against the seedling length of Lepidium sativum L., Medicago sativa L., Phleum pratense L., and Echinochloa crus-galli (L.) P. Beauv. Bioassay-guided fractionation of the A. xylocarpa leaf extracts led to isolating and identifying two compounds: vanillic acid and trans-ferulic acid. Both compounds were applied to four model plants using different concentrations. The results showed both compounds significantly inhibited the model plants’ seedling length in a species-dependent manner (p < 0.05). The phytotoxic effects of trans-ferulic acid (IC50 = 0.42 to 2.43 mM) on the model plants were much greater than that of vanillic acid (IC50 = 0.73 to 3.17 mM) and P. pratense was the most sensitive to both compounds. In addition, the application of an equimolar (0.3 mM) mixture of vanillic acid and trans-ferulic acid showed the synergistic effects of the phytotoxic activity against the root length of P. pratense and L. sativum. These results suggest that the leaves of A. xylocarpa and its phytotoxic compounds could be used as a natural source of herbicides.

“…In our two previous studies, we examined the phytotoxicity of extracts of Albizia richardiana leaves against the seedling growth of Lepidium sativum , Medicago sativa L. (crop plants), Echinochloa crus-galli (L.) P. Beauv. and Phleum pratense L. (species of weeds) and observed notable growth suppression [ 38 , 43 ]. To validate those results, in this study, we also examined the allelopathic potential of the extracts of Albizia richardiana leaves against the growth of Lactuca sativa (lettuce) and Lolium multiflorum (Italian ryegrass).…”

“…Measuring the lengthening or shortening of shoots and roots is commonly employed to determine allelopathic activity [ 64 ]. In our two previous studies, two phytochemical substances, dehydrovomifoliol and loliolide [ 38 ], and another two allelopathic substances, 3-hydroxy-4-oxo-β-dehydroionol (novel compound) and 3-oxo-α-ionone [ 43 ], were isolated and identified from Albizia richardiana leaf extracts. In this study, we have also isolated another three phytochemical substances from Albizia richardiana leaf extracts: compounds 1 , 2 , and 3 ( Figure 3 ).…”

“…ODS AQ-325; YMC Ltd., Kyoto, Japan). Phytotoxic activity was measured using the Lepidium sativum (cress) assay experiment for every chromatographic step according to Hossen et al [ 38 ], resulting in the isolation of three compounds: compound 1 , 2 , and 3 (4,5-dihydrovomifoliol, 3-hydroxy-5α,6α-epoxy-β-ionone, and 3-(2-hydroxyethyl)-2,4,4-trimethyl-2cyclohexen-1-one) ( Figure 1 ). These compounds were then purified once again using reverse-phase HPLC (4.6 × 250 mm I.D., S-5 µm, Inertsil ® ODS-3; GL Science Inc., Tokyo, Japan) at a flow rate 0.8 mL/min with 25% aqueous methanol obtained at retention times of 72–78, 80–84, and 90–102 min.…”

These two residues of leaf powder were mixed and evaporated with a rotary evaporator at 40 • C. The leaf extracts were dissolved in methanol (250 mL) to produce bioassay concentrations of 3, 10, 30, 100, 300, and 1000 mg dry weight (DW) equivalent extract/mL, and assay tests were conducted with the Albizia richardiana crude extracts against the selected species for this study as recommended by Hossen et al [38]. The exact quantity of residues was transferred to a filter paper (No.…”

The global population is increasing day by day. To meet the food demand for such a huge number of people, crop production must increase without damaging the environment, and to prevent synthetic chemical herbicides from polluting the environment, controlling weeds using bioherbicides is essential. Accordingly, using phytotoxic substances obtained from plants for biological weed management has attracted attention. The plant Albizia richardiana possesses phytotoxic compounds that have been previously recorded. Hence, we have conducted this research to characterize more phytotoxic compounds in Albizia richardiana. Aqueous methanolic extracts of Albizia richardiana plant significantly restricted the growth of the examined plants lettuce and Italian ryegrass in a species- and concentration-dependent manner. Three active phytotoxic compounds were isolated through various chromatographic methods and identified as compound 1, 2, and 3. Compound 3 exhibited stronger phytotoxic potentials than the other two compounds and significantly suppressed the growth of Lepidium sativum (cress). The concentration of the compounds required for 50% growth reduction (I50 value) of the Lepidium sativum seedlings ranged between 0.0827 to 0.4133 mg/mL. The results suggest that these three phytotoxic compounds might contribute to the allelopathic potential of Albizia richardiana.

Majority of different kinds of metabolites having therapeutic characteristics are thought to be stored in medicinal plants. So, the present study was aimed to explore the crude extract of leaves and stem of R. afghanicum for phytochemical screening and various pharmacological activities. Toxicological studies at 100 mg/kg showed 60 % mortality where its safe dose level was 90 mg/kg. Phytochemical screening revealed the presence of alkaloids, glycosides, flavonoids and tannins in both extracts. Bacterial strains were susceptible to (RLEt) and (RLM) crude extracts except Staphylococcus aureus. RSM showed maximum anti‐inflammatory activity (20.16 %) followed by RSEt (20.14 %) where lowest activity was displayed by RLEt (18.46 %). Phytotoxic activity showed a substantial dose‐dependent phyto‐inhibition of Lemna minor. An outstanding cytotoxic potential was displayed with LD50 values of 9.46 and 13.03 μg/ml in both stem extracts. RLEt demonstrated a dose‐dependent pain relief at 30, 60 and 90 mg/kg which was 31 %, 40 % and 52 % respectively. A considerable spasmolytic action was observed by the shrinkage of jejunum muscle in albino mice. RLEt at 1000 ppm showed (17 mm) and RLM at 1000 ppm showed (16 mm) zone of inhibition against Aspergillus niger. These findings support and corroborate the traditional applications of R. afghanicum for treating digestive, analgesic and inflammatory ailments.
