“…The relative configuration of glucose anomeric proton was confirmed as β on the basis of the coupling constant ( J 1′, 2′ = 7.8 Hz). Furthermore, the glucose was identified as D-form by GC analysis comparing with a standard after acid hydrolysis [12, 13]. The relative configuration of 1 was same with mascaroside I by comparison of the NMR data.…”

Five new ent-kaurane diterpenoids, named mascaroside III–V (1–3), and 20-nor-cofaryloside I–II (4–5), together with seven known diterpenoids, were isolated from methanol extracts of the green coffee beans of Yunnan Arabica Coffee. Their chemical structures were elucidated by extensive spectroscopic analyses. Meanwhile, cytotoxicity assay against HL-60, A-549, SMMC-7721, MCF-7 and SW480 cell lines showed that they have not evident inhibition of cytotoxicity.Graphical AbstractElectronic supplementary materialThe online version of this article (doi:10.1007/s13659-016-0099-1) contains supplementary material, which is available to authorized users.

Three compounds were obtained from Sabia parviflora Wall., and their structures were identified through nuclear magnetic resonance (NMR) spectroscopy, particularly 2-dimensional (2D)-NMR. The molecular masses were determined using quadrupole-time-of-flight-mass spectrometry. Electronic circular dichroism spectra were used to determine the absolute configuration of compound 1. The 3 new compounds were identified as 2,2,7,7-tetramethyl-8S,10-dihydroxy-2,7,8,9-tetrahydro-2H-naphtha[2,3-b]pyran-6-one-10- O- β-D-glucopyranoside, (2Z)-4-(3-carboxy-4-hydroxyphenyl)-2-methylbut-2-enoic acid, and (2Z)-5-(3-carboxy-4-hydroxyphenyl)-5-oxo-2-methylpent-2-enoic acid. The liver protective activities of these compounds were tested by HepG2 and LO2 cell lines, which were induced using free fatty acids.

The plants of the genus Phyllanthus (Euphorbiaceae) have been used as traditional medicinal materials for a long time in China, India, Brazil, and the Southeast Asian countries. They can be used for the treatment of digestive disease, jaundice, and renal calculus. This review discusses the ethnopharmacological, phytochemical, and pharmacological studies of Phyllanthus over the past few decades. More than 510 compounds have been isolated, the majority of which are lignins, triterpenoids, flavonoids, and tannins. The researches of their remarkable antiviral, antioxidant, antidiabetic, and anticancer activities have become hot topics. More pharmacological screenings and phytochemical investigations are required to support the traditional uses and develop leading compounds.
