TL;DR: Three new bisindole alkaloids, 3'-(2-oxopropyl)-19,20-dihydrotabernamine (1:), 3'- (2-Oxopropylene)-19-20- dihydrovobparicine (3:), and 20 known compounds were isolated from the aerial parts of Tabernaemontana bufalina using spectroscopic methods to elucidate the structures of these alkaloid structures.

TL;DR: Spiroalanpyrroids A (1) and B (2), two sesquiterpene alkaloids with an unprecedented eudesmanolide-pyrrolizidine spiro[5.5] framework, were isolated together with two new SESQUERPene-amino acid adducts, helenalanprolines A (3) and b (4), from the roots of Inula helenium as mentioned in this paper.

TL;DR: In this article, the minor compounds in Jing liqueur, the concentration of metals, amino acids, and polysaccharides, and evaluate their Nrf2 activity and cytotoxicity were determined.

TL;DR: A new monomeric nidulalin D and four known analogues, together with a xanthone dimer bearing an unprecedented heptacyclic 6/6/six/6-6/6 /6/Six/6 system, were isolated from Aspergillus sp.

TL;DR: Two new compounds heliotropiumides A and B, phenolamides each with an uncommon carbamoyl putrescine moiety, were isolated from the seeds of a naturalized Hawaiian higher plant in the borage family, which is widely used for the treatment of ciguatera fish poisoning.
