The title compound, C(24)H(39)NO(6) [systematic name: (1α,6α,14α,16β)-N-ethyl-6,16-dimeth-oxy-4-meth-oxy-methylaconitane-1,8,14-triol], is a C(19)-diterpenoid alkaloid from the roots of Aconitum flavum Hand. The mol-ecule has an aconitane carbon skeleton with four six-membered rings and two
Eight new C19-diterpenoid alkaloid arabinosides, named aconicarmichosides E-L (1-8), were isolated from an aqueous extract of the lateral roots of Aconitum carmichaelii (Fu Zi). Their structures were determined by spectroscopic and chemical methods including 2D NMR experiments and acid hydrolysis.
Amino alcohol alkaloids are the active components in the lateral root of Aconitum carmichaelii Debx. (Fuzi), and they have a variety of pharmacological activities. However, the chemical fingerprints of the ester alkaloids reported to date were mainly obtained from high-performance liquid
Aconitum jaluense Komar. (Ranunculaceae) is one of the Aconitum plants growing in Korean peninsula. An investigation of the alkaloidal constituents of this species led to the isolation of seven C19-norditerpenoid and a C20-diterpenoid alkaloid. Three of them have been identified as neoline,
Despite their well-known toxicity, Aconitum species are important traditional medicines worldwide. Aconitum carmichaelii, known in Chinese as (fuzi), is an officially recognized traditional Chinese medicine with characteristic analgesic and anti-inflammatory activities, whose principal
Aconitum carmichaelii Debeaux is a widely used herbal medicine, which has anti-inflammatory and analgesic activities. However, due to its high toxicity, poisoning incidents often occur all over the world. To systematically understand the pharmacokinetics (PK) and tissue distribution of A.
An efficient and refined method for the separation of six aconitine-type alkaloids from the alkaline prepared "Kusnezoff monkshood root" was extablished. It is the first study that two new lipo-alkaloids were successfully isolated from refined sample by pH-zone-refining counter-current
Aconitum brachypodum is traditionally known to be toxic chinese medicie, but its chemical constituents is not enough studied to date. To further elucidate the chemical constituents of A. brachypodum, 80% ethanol extract of A. brachypodum collected from Dong-Chuan area was investigated, which led to
A rapid, convenient and effective identification method of alkaloids was established and an attempt on isolating and analyzing the alkaloids in Aconitum pendulum Busch was conducted successfully. In this article, four high-content components including deoxyaconitine, benzoylaconine, aconine and
Two new alkaloids, aconicarmine (1) and aconicaramide (5), were isolated from the EtOH extract of the lateral roots of Aconitum carmichaelii, together with five known compounds: fuziline (2), neoline (3), N-ethylhokbusine B (4), 5-hydroxymethylpyrrole-2-carbaldehyde (6), and oleracein E (7). Their
A new denudatine-type C20-diterpenoid alkaloid, designated as sinchianine (1), together with eight known diterpenoid alkaloids, 12-acetyl-12-epi-napelline (2), 12-epi-napelline (3), neoline (4), talatisamine (5), 14-O-acetylsenbusine A (6) and benzoylaconine (7), songorine (8) and aconitine (9),
Diterpene alkaloids neoline (1), napelline (2), isotalatizidine (3), karakoline (4), senbusine A (5), senbusine C (6), aconitine (7) and taurenine (8) were identified from Aconitum napellus L. subsp. firmum, four (2-4, 6) of which are reported for the first time from this plant. The structures were
Aconitum laciniatum is used in Bhutanese traditional medicine for treating various chronic infections and inflammatory conditions. We carried out in-depth isolation and characterization of the phytochemicals from the root component and determined the anti-inflammatory effects of the isolated
As a representative variety of hypertoxic herbs, aconite has a very high medicinal value but certain security risks. With the advance of urbanization and industrial transfer and upgrading, traditional geo-authentic regions and emerging regions have gradually coexisted. However, there are significant
Four new and five known norditerpenoid alkaloids were isolated from the processed tubers of Aconitum carmichaeli. The new alkaloids are 14-O-cinnamoylneoline (3), 14-O-anisoylneoline (4) 14-O-veratroylneoline (5), and lipo-14-O-anisoylbikhaconine (8). The known alkaloids are neoline (1),
