“…Moreover, the unequal susceptibility of the tested species to the extracts could be due to inherent differences in the biochemicals involved in the process [34]. The species specificity of phytotoxic substances has also been demonstrated for other allelopathic plant species [35][36][37]. In general, plant extracts comprise a mixture of various bioactive and inactive compounds with different polarities [38].…”

Senna garrettiana (Craib) Irwin & Barneby (Fabaceae) is a medicinal plant known to be rich in biologically active compounds that could be exploited to produce bioherbicides. The present study was conducted to explore the allelopathic potential and phytotoxic substances of S. garrettiana. Extracts of S. garrettiana leaves were found to significantly inhibit the growth of Lepidium sativum L. and Echinochloa crus-galli (L.) P. Beauv. (p ≤ 0.05). The phytotoxic substances were isolated and identified as vanillic acid and ferulic acid by bioassay-directed fractionation and spectral data analysis. The two compounds were shown to significantly inhibit the seed germination, seedling growth, and dry biomass of L. sativum. Based on the concentration required for 50% growth inhibition (defined as IC50), the roots of L. sativum were the most sensitive to the compounds, and the inhibitory effect of ferulic acid (IC50 = 0.62 mM) was >1.3 times more potent than that of vanillic acid (IC50 = 0.82 mM). In addition, a mixture of the two compounds (0.3 mM) resulted in synergistic inhibitory activity against the L. sativum roots compared with the individual compounds. These results suggest that the extracts of S. garrettiana leaves and their phytotoxic compounds have potential as candidate natural herbicides.

“… 1 Teas can be obtained quickly by infusion, a conventional extraction method that uses hot water as a solvent and is associated with efficient extraction of polyphenols, compared to other techniques. 2 The tea of T. spathacea , a herbaceous ornamental plant, is already popularly used as a functional drink in South and Central America and in Southeast Asia, 3 and has the potential to be established internationally, due to its polyphenol content and antioxidant capacity. 4 …”
