“…A characteristic ion can be seen at m/z 165 due to the RDA cleavage. The MS data were in agreement with those previously reported, and compounds 1 and 5 were identified as (+)-7-epi-sesamin-dicatechol and (±)-3,3′-bisdemethylpinoresinol, respectively [ 22 , 23 ].…”

“…The fragment ion of m/z 165 was similar to americanol A and isoamericanol A. By comparing the fragmentation pathways with those of the references, compounds 6, 10, 13, 14, 15, and 16 could be tentatively identified as isoamericanol B1, isoamericanol B2, isoamericanol C1, isoamericanol C2, princepin, and isoprincepin [ 24 ], which was in accord with the findings of Chen et al [ 23 ]. Those compounds were also named sesquineolignans because they were structurally formed by the oxidative polymerization of three phenylpropyl.…”

“…Compound 12 was identified as isoamericanin A, where one hydroxymethyl group in isoamericanol A was oxidized to an aldehyde group, in comparison with their spectral features. This compound had also been found in the seed testa of Vernicia fordii [ 23 ].…”

“…The distinguished fragment ion of m/z 119 indicated the loss of H 2 O, and another major fragment ion m/z 108 was obtained by the loss of CO. Considering that the above fragments were the same as in the previous report [ 28 ], compound 3 was tentatively identified as 2,4-dihydroxybenzaldehyde, which had been detected in the seed testa of V. fordii [ 23 ].…”

“…Furthermore, fragment ions of m/z 493 and other fragment ions were similar to those of (iso) princepin. Those three compounds were tentatively identified as isodiverniciasin A, diverniciasin C, and diverniciasin B, which have been detected in the seed testa of V. fordii [ 23 ].…”

The environmental pollution, pesticide resistance, and other associated problems caused by traditional chemical pesticides with limited modes of action make it urgent to seek alternative environmentally-friendly pesticides from natural products. Tung meal, the byproduct of the detoxified Vernicia fordii (Hemsl.) seed, has been commonly used as an agricultural fertilizer and as a pesticide. However, its active insecticidal extracts and ingredients remain elusive. In the present study, the contact toxicities of tung meal extracts against the agricultural and forest pests like O. formosanus and P. xylostella were examined. Our results showed that ethyl acetate and petroleum ether extracts showed the strongest toxicity against O. formosanus and P. xylostella, respectively. In order to further explore the chemical profiles of the ethyl acetate and petroleum ether extracts, UPLC-Q/TOF-MS and GC-MS analyses have been performed, and 20 and 29 compounds were identified from EA and PE extracts, respectively. The present study, for the first time, verified the noteworthy insecticidal activities on the aforementioned agricultural and forest pesticides and revealed the potential active parts and chemical composition, which are conducive to further exploiting the potential of tung meal as a natural plant-derived insecticide for biological control of agricultural and forest pests.

A report on the Pithecellobium dulce tree is provided in this review. The main characteristics of the tree, its chemical composition, traditional applications and future application in the bioenergy area are addressed. Pithecellobium dulce is a leguminous tree characterized by being fast growing, nitrogen fixing and largely available. In addition, it is distinguished by growing in different types of soils from acid to alkaline and with little water. This review could serve as a scientific basis to promote and carry out new research work focused on individual and comprehensive use for various bioenergetic processes, from the different parts that make up the P. dulce tree such as its leaves, pods, branches, flowers, fruit and seeds. Among the bioenergetic processes that could be developed are the production of bioethanol, biodiesel, biogas, heterogeneous catalysts, biochar, activated carbon and nanoparticles, among other applications.

An undescribed tigliane diterpenoid, 13-acetyl-12,17-di-O-tiglylphorbol (1), along with thirty-three known components, were isolated from the stems of Croton tiglium L. var. xiaopadou (Euphorbiaceae). Their structures were established based on spectroscopic data and ECD spectra. Their anti-neuroinflammatory effects were evaluated in LPS-induced BV-2 microglia. Thirteen tested compounds showed significant inhibitory activities, especially compounds 10, 16, 18 and 21 exhibited an inhibitory effect with IC 50 values in the range of 12.39 to 17.80 μM, which are comparable with that of the positive control (minocycline, IC 50 13.92 μM).
