Based on previous studies on Atractylodes lancea (Thunb.) DC., this paper focuses on the chemical composition of fresh rhizome of Atractylodes lancea. And fifteen compounds were isolated, including six guaiane-type sesquiterpenoids (1–5), one eudesmane-type sesquiterpenoid (6), one monoterpene glycoside (7), one polyacetylene glycoside (8), one phenylpropanoid glycoside (9), two nucleosides (10–11)

Effect of leaf development on the composition of Coleus amboinicus Lour. hydroethanolic extracts Biochem. Syst. Ecol. (IF 1.6) Pub Date : 2023-10-20 Guilherme Perez Pinheiro, Gabriela Ferreira da Silva, Alexandra Christine Helena Frankland Sawaya
Coleus amboinicus Lour. is an aromatic shrub widely used for therapeutic and culinary purposes. Although its phytochemistry has been broadly reported in the literature, mainly essential oil composition, little is known about the effect of developmental factors on the composition of C. amboinicus extracts. Thus, we evaluated the chemical composition of C. amboinicus extracts from leaves in different

Chemical constituents from Mallotus tetracoccus (Roxb.) Kurz (Euphorbiaceae) and their chemotaxonomic significance Biochem. Syst. Ecol. (IF 1.6) Pub Date : 2023-10-20 Qiong Wei, Quanyu Yang, Yifan Xie, Xiaoting He, Xiaoli Li, Weilie Xiao
The phytochemical investigation of the leaves and twigs of Mallotus tetracoccus (Roxb.) Kurz led to the isolation of nineteen compounds, including four lignans (1–3, 18), three flavonoids (4–6), four kaurane diterpenes (7–10), two sesquiterpenes (11–12), four phenols (13–16), one fatty acid (17), and one triterpene (19). Their structures were elucidated by spectroscopic analyses and published data

Phytochemical investigation on the roots of Piper nigrum Linn. and the chemotaxonomic significance Biochem. Syst. Ecol. (IF 1.6) Pub Date : 2023-10-18 Peng Zhang, Zhi-Yong Xu, Xiao-Xiao Huang, Shao-Jiang Song
Phytochemical investigation into the roots of Piper nigrum Linn. led to the isolation of ten compounds, including six lignans (1–6), two aromatic compounds (7–8), one lactone (9), and one sesquiterpenoid (10). Compounds 1, 2, 4, 7, 8, 9, and 10 were isolated from Piperaceae for the first time. The structures of these compounds were elucidated by comprehensive spectral methods, including UV, NMR, CD
