“…In the 1 H NMR spectrum (Table 1) two cyclopropane-methylene protons as an AX system at δ H 0.28 and 0.41 (each 1H, d, J 4.2 Hz, H 2 -19) together with nine tertiary methyl groups indicated a cycloartane triterpenoid structure. The 1 H NMR and 13 C APT data were closely related to those of beesioside I (Tables 1, 2) (Sakurai et al, 1990). The differences showed that 7 had a carbonyl group attached to C-12, which caused C-12 to move to a lower field, and the chemical shift is greatly increased to δ C 216.6).…”

Phytochemical studies on the rhizomes of Actaea asiatica led to the isolation of seven new cycloartane triterpenes, actaticas A−G (1−7). Their structures were determined by NMR, HRESIMS, and chemical analysis. All the isolates were evaluated for their antiproliferative activity against HT-29 and McF-7 cell lines. The results showed that all the compounds displayed cytotoxicity. All compounds showed significant inhibitory effects with IC50 values of 9.2–26.4 μM.

Two new polyoxygenated steroids, reticulatic acid (1) and reticulatin (2), together with a known compound 3,22,25‐trihydroxy‐16‐24,20‐24‐bisepoxy‐3β,16β,20S,22R,24S‐cholest‐5‐ene (3), were isolated from the CH2Cl2/EtOH extract of the South China Sea gorgonian coral Subergorgia reticulata. Their structures were established on the basis of extensive spectroscopic analysis. The absolute stereochemistry of compounds 2 and 3 was determined by the X‐ray crystallographic analysis and the Mosher ester determination.
