OBJECTIVETo study the chemical constituents from Delphinium honanense var. piliteram.

METHODThe constituents were isolated and purified with chromatographic methods, identified by NMR, MS and IR.

RESULTSix compounds were isolated and elucidated as siwanine E (1), isoatisine (2), 12-epi-napelline (3), acontine (4), ajadelphinine (5) and beta-sitosterol (6).

CONCLUSIONCompounds 1-6 are all isolated from the plant for the first time.

Dried herb of Delphinium brunonianum Royle (Ranunculaceae) has long been used under the herbal name "Xiaguobei" (Delphinii Brunoniani Herba) in traditional Tibetan medicine and prescribed for the treatment of influenza, itchy skin rash and snake bites. In order to find a useful and convenient method for the identification of microscopic features, the technique of fluorescence microscopy was applied to authenticate "Xiaguobei" of Tibet. The transverse sections of stem and leaf, as well as the powder of "Xiaguobei" were observed to seek for typical microscopic features by normal light and fluorescence microscopy. A style-like, single-cell glandular hair containing yellow secretions on the leaf, young stem and sepal of "Xiaguobei" was found. Under the fluorescence microscope, the xylem and pericycle fiber group emitted significant fluorescence. This work indicated that fluorescence microscopy could be an useful additional method for the authentication work. Without the traditional dyeing methods, the main microscopic features could be easily found by fluorescence microscopy. The results provided reliable references for the authentication of "Xiaguobei".

The present study was designed to determine the chemical constituents of Delphinium caeruleum Jacq. ex Camb.. The chemical constituents were isolated and purified by column chromatography with silica gel, ODS, and Sephadex LH-20. Their structures were elucidated by IR, MS, and NMR. Ten compounds were obtained and identified as caerudelphinine A (1), lycoctonine (2), talitine B (3), talitine A (4), talitine C (5), tatsienine-V (6), d-magnoflorine (7), 2-trimethyl-ammonio-3-(3-indolyl) propionate (8), vakhmatine (9), and delatisine (10). Compound 1 was a new lycoctonine-type C19-diterpenoid alkaloid, and compounds 4-10 were isolated from this plant for the first time.
