scopolia sinensis/scopolamine

Potions from plants, now known to contain scopolamine, were used in antiquity and the middle ages. However, wide-spread application of drugs for induction of insensibility to pain did not occur, probably because of side-effects and unpredictable dose-effect relationships. The word "scopolamine" is

A non-aqueous solid phase extraction (SPE) method utilizing silica based strong cation exchange (SCX) was developed and optimized for the enrichment of alkaloids. In this method, silica based SCX SPE columns were used for the elimination of non-alkaloid compounds and the preconcentration of

Scopolia lurida, a medicinal plant native to the Tibetan Plateau, is among the most effective producers of pharmaceutical tropane alkaloids (TAs). The hyoscyamine 6β-hydroxylase genes of Hyoscyamus niger (HnH6H) and S. lurida (SlH6H) were cloned and respectively overexpressed in hairy root cultures

A uniformly sized molecularly imprinted polymer (MIP) for atropine has been prepared. The MIP was prepared using 2-(trifluoromethyl) acrylic acid and ethylene glycol dimethacrylate as a functional monomer and cross-linker, respectively, by a multi-step swelling and thermal polymerization method. The

A rapid method that does not require a complicated preparation was developed for determining by HPLC the content of atropine (At) and scopolamine (Sc) in a sample of scopolia extract powder. The sample solution for HPLC was extracted using 0.1 mol/L HCl/methanol (8:2). At and Sc were separated using

Anisodine (Ani), a new selective M receptor blocking agent, was isolated from Scopolia tangutica in China. The structure of Ani is similar to scopolamine. Ani (2.5, 5 mg.kg-1 i.v., or 0.6 mg.kg-1 icv) increased the rate of phrenic nerve discharges (PND), while the time of inspiration and expiration,

Scopolia tangutica (S. tangutica) is a traditional Chinese medicinal plant used for antispasmodics, anesthesia, analgesia and sedation. Its pharmacological activities are mostly associated with the antagonistic activity at muscarinic acetylcholine receptors (mAchRs) of several known alkaloids such

Four new hydroxycinnamic acid amides, scotanamines A-D (1-4), and seven known alkaloids, including N (1),N (10)-di-dihydrocaffeoylspermidine (5), scopolamine (6), anisodamine (7), hyoscyamine (8), anisodine (9), caffeoylputrescine (10), and N (1)-caffeoyl-N (3)-dihydrocaffeoylspermidine (11), were

Scopolia extract (SE) contains hyoscyamine and scopolamine, which are both anticholinergic. It is usually used as a patent medicine to treat gastrointestinal disorders, to relieve spasmotic discomfort, or to decrease the secretion of gastric acid. Poisoning by SE presents similar symptoms and signs

The mass production of tropane alkaloids from adventitious root cultures of Scopolia parviflora, in small-scale bubble column bioreactor (BCB) was attempted. Adventitious roots of S. parviflora produced relatively enhanced levels of scopolamine and hyoscyamine in bioreactor compared to flask type

A rapid micropropagation system for Scopolia parviflora Nakai (Solanaceae), a rare medicinal plant native to Korea, was established using rhizome cultures. Shoots that originated from adventitious shoots of the rhizome were multiplied when the rhizomes were cultured on half-strength B5 liquid medium

In the present paper, effects of scopolia drugs (scopolamine, anisodine, anisodamine) on experimental gastric mucosal lesion models in rats were investigated. Scopolia drugs were found to be effective anti-ulcer agents in three experimental gastric ulcer models (i.e. cold-restraint stress induced

The production of tropane alkaloids during differentiation and de-differentiation of Scopolia parviflora calli was studied. Tropane alkaloid production drastically decreased during calli de-differentiation. Scopolamine (1) production decreased after 10 days of culture, whereas that of hyoscyamine
