Two new ent-kaurane-type diterpenoids, E-semiaquilegin (1) and Z-semiaquilegin (2), together with eight known compounds (3–10) were isolated from the dried roots of Semiaquilegia adoxoides (DC.) Makino. The structures of compounds 1 and 2 were elucidated mainly by 2D NMR techniques including 1H–1H COSY, HSQC, HMBC, NOESY as 16α-hydroxy-ent-kaurane-17,20-di-(3,4-dihydroxy-E-cinnamoyl) ester and its (Z)-isomer.

Phytochemical investigation of Semiaquilegia adoxoides was initiated in view of its common usage in traditional Chinese medicine and the scarcity of previous phytochemical studies. Fractionation of an ethanol extract from the roots of this plant led to the isolation and identification of a novel cyanogenic glycoside, 2-(β-d-glucopyranosyloxy)-4-hydroxybenzeneacetonitrile (1). The structure of 1 was elucidated on the basis of IR, FAB-MS, 1D and 2D NMR spectral analysis.

Extraction of Tripterygium doianum (Celastraceae) afforded five new diterpenoids and 11 known diterpenoids belonging to the ent-kaurane and abietane families. Their structures were established based on spectroscopic studies. The isolated compounds showed moderate cytotoxicity against human tumor cell assays.

Two new diterpenoids of the pimarane type, flavidusin A and B, as well as seven known compounds, glutinosin, ent-kauran-16 beta, 17-diol, siegesbeckiol, 16-hydroxy feruginol, hinokiol, maslinnic acid and 5-hydroxy-7,4'-dimethoxyflavone were isolated from the dried leaves of Isodon flavidus. The new diterpenoids were identified as isopimar-8(14)-15, 16-diol and 15,16-dihydro-15 beta-hydroxy-14 alpha,16-epoxyisopimar-8(9)-ene. The absolute configuration of glutinosin is revised to the isopimarane ...

Abstract Extracts of the tropical rainforest trees Homalanthus acuminatus and Chrvsobalanus icaco were active in the NCI AIDS-antiviral screen. Diterpenes 1–4 were found in H . acuminatus , while two (6,7) were found in C . icaco . Compounds 1 and 6 were active in the anti-HIV screen; 1, 3 and 4 were previously unknown.

Tricyclic compounds 756 and 757 have been found to exist in low concentration in lavender oil. Structure proof was realized by selenium dioxide oxidation of α-cedrene. Hydrogenation of 756 and subsequent copper-catalyzed oxidation of the saturated aldehyde furnished 757 [347].

This chapter reviews the correlation between phylogeny, chemical constituents, and pharmaceutical aspects of Ranunculaceae (i.e., a pharmacophylogenetic study of this medicinal family). Phytochemical, ethnopharmacological, and pharmacological information are integrated in the context of systematics and molecular phylogeny of Ranunculaceae. Chemical components of this family include several representative groups: benzylisoquinoline alkaloid, ranunculin, triterpenoid saponin, diterpene alkaloid, e...

Abstract Natural products have historically been, and continue to be, an invaluable source for the discovery of various therapeutic agents. Oridonin, a natural diterpenoid widely applied in traditional Chinese medicines, exhibits a broad range of biological effects including anticancer and anti-inflammatory activities. To further improve its potency, aqueous solubility and bioavailability, the oridonin template serves as an exciting platform for drug discovery to yield better candidates with uni...

AbstractContext Hydrogen peroxide (H2O2)-induced damage in the lens epithelium leads to cell death and cataract. Semiaquilegia adoxoides (DC.) Makino (Ranunculaceae), a folk medicine of Hmong (an ethnic group of China), has been traditionally used to treat cataract; however, the underlying molecular mechanism is yet to be uncovered.Objective This study aimed to investigate whether the n-butanol extract of S. adoxoides (nSA) is effective against the H2O2-induced oxidative stress in human lens epi...

Abstract Through bioassay-guided fractionation, thirteen compounds (1-13) were isolated from the dry root of Semiaquilegia adoxoides, known as Tiankuizi in traditional Chinese medicine (TCM). Among these, four benzoic acid derivatives (1, 2, 4, 5), one 4,6-dimethoxy-5-methyl-2H-pyran-2-one (10) and one 1,2,3-propanetriol (13) were found for the first time in S. adoxoides. This is the first record of compound 10 from a natural source. 4-Hydroxybenzoic acid (1) and 3,4-dihyroxybenzoic acid (2) sho...

Inflammatory bowel disease (IBD) affects the mucosal lining of the gastrointestinal tract; the etiology is unknown and treatment is directed at systemic immunosuppression. Natural products, including medicinal herbs, have provided approximately half of the drugs developed for clinical use over the past 20 years. The purpose of our current study was to determine the effects of a novel combination of herbal extracts on intestinal inflammation using a murine model of IBD. Female Swiss-Webster mice ...
