“…This species is both ecologically and economically important deciduous tree in agroforestry systems in the tropics and is mainly distributed in Thailand, Vietnam, Cambodia, Laos, and Burma [32]. It is used as a traditional medicine against inflammatory ocular diseases, sore throat, and food poisoning [33]. Previous studies have shown different biological activities of this plant, such as antioxidant, antidiabetic, antimicrobial, and anti-inflammatory [34][35][36].…”

“…Various compounds have been reported in A. xylocarpa seeds, such as chlorogenic acid, ferulic acid, gallic acid, taxifolin, caffeic acid, rosmarinic acid, daidzein, isovanillic acid, cinnamic acid, vanillin, naringenin, p-coumaric acid, cholesterine, campesterol, campestanol, and stigmasterol [39]. Twelve compounds were isolated from A. xylocarpa leaves, including kaempferol-7-Oβ-D-glucopyranoside, friedelin, β-sitosterol, butyl benzoate, stigmas-ta-4, 25-dien-3-one, epifriedelanol, stigmasterol, palmitic acid, linoleic acid, α-linolenic acid, and (3S,5R,6R,7E)-3,5,6-trihydroxy-7-megastigmen-9-one [33]. It was reported that some phenolic acids, such as p-coumaric acid, act as phototoxic substances, which are released from different plant parts or decomposed plant residues.…”

Isolation and Identification of Two Potent Phytotoxic Substances from Afzelia xylocarpa for Controlling Weeds

et al. 2021

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.

“…The newly introduced species of Diaporthe were associated with different medicinal plants, comprising D. afzeliae on Afzelia xylocarpa , D. bombacis on Bombax ceiba , D. careyae on Careya sphaerica , and D. samaneae on Samanea saman . These plant species have been used as traditional medicines in tropical countries, including Thailand, and have been reported on concerning their various phytochemicals and pharmacological activities [ 69 , 70 , 71 , 72 , 73 , 74 , 75 ]. To the best of our knowledge, none of the Diaporthe species have been isolated from these host genera, making this the first report of such a host association [ 38 ].…”

During our investigations of the microfungi on medicinal plants in Thailand, five isolates of Diaporthe were obtained. These isolates were identified and described using a multiproxy approach, viz. morphology, cultural characteristics, host association, the multiloci phylogeny of ITS, tef1-α, tub2, cal, and his3, and DNA comparisons. Five new species, Diaporthe afzeliae, D. bombacis, D. careyae, D. globoostiolata, and D. samaneae, are introduced as saprobes from the plant hosts, viz. Afzelia xylocarpa, Bombax ceiba, Careya sphaerica, a member of Fagaceae, and Samanea saman. Interestingly, this is the first report of Diaporthe species on these plants, except on the Fagaceae member. The morphological comparison, updated molecular phylogeny, and pairwise homoplasy index (PHI) analysis strongly support the establishment of novel species. Our phylogeny also revealed the close relationship between D. zhaoqingensis and D. chiangmaiensis; however, the evidence from the PHI test and DNA comparison indicated that they are distinct species. These findings improve the existing knowledge of taxonomy and host diversity of Diaporthe species as well as highlight the untapped potential of these medicinal plants for searching for new fungi.

“…The extract of Afzelia genus plants showed antioxidant (Akinpelu et al 2010), antidiabetic (Oyedemi et al 2011), antimicrobial, and anti-inflammatory activities (Akah et al 2007). In China, A. xylocarpa is widely used as a folk medicine to treat inflammation and eye diseases, sore throat, and food poisoning (Cai et al 2018). Therefore, A. xylocarpa has potential medicinal value.…”

The first complete chloroplast genome (cpDNA) sequence of Afzelia xylocarpa was determined from Illumina HiSeq pair-end sequencing data in this study. The cpDNA is 159,115 bp in length, contains a large single-copy region (LSC) of 88,164 bp and a small single-copy region (SSC) of 19,495 bp, which were separated by a pair of inverted repeats (IR) regions of 25,748 bp. The genome contains 128 genes, including 83 protein-coding genes, 8 ribosomal RNA genes, and 37 transfer RNA genes. The overall GC content of the whole genome is 36.1%, and the corresponding values of the LSC, SSC, and IR regions are 33.7%, 29.6%, and 42.6%, respectively. Further phylogenomic analysis showed that A. xylocarpa, Tamarindus indica, and Crudia harmsiana are clustered in a clade in the Detarioideae subfamily.
