Abstract

Rhizome wide-creeping, densely scaly; scales lanceolate, long-acuminate, rufo-brown, nitid, thick, entire; frond 2-4 cm apart, stipe 30-50 cm long, 3 mm thick near base, green or pale straminous, smooth, glabrous above base, rounded beneath, lower part flattened with sharp edge above and upper part deeply grooved, lamina ovate, bifurcate at the tip of stipe into two similar pinnae of oblong outline, 30-40 cm long, 13-16 cm broad, acuminate, axillary bud large, densely scaly, scales ovate, entire, with long subulate apices; pinnules linear-lanceolate, acuminate, short-petiolate, the lower ones on the exterior side of rachilet much the longest, to 12 cm long, 2 cm broad, gradually shortened up

Bisbenzylisoquinoline Alkaloids

“…K+ (60mM)-induced contraction of thoracic aorta strips was inhibited by the alkaloid, and Ca+2 related vascular effects were antagonized by both the alkaloid and verapamil. Thus, vascular relaxation due to the alkaloid is probably because of Ca*2 antagonism (rabbit) (186).…”

Separation, identification and rapid determination of liensine, isoliensinine and neferine from embryo of the seed of Nelumbo nucifera GAERTN. by liquid chromatography coupled to diode array detector and tandem mass spectrometry

“…Since the first isolation of liensinine in 1962 [17], the three alkaloids have received considerable attention because of their reputation of chemical and biological properties and many studies were focused on the isolation, quality analysis, pharmacology and pharmaceutical preparation of them [18][19][20][21][22][23][24][25]. However, their pharmacological and pharmaceutical studies often suffer from the limits of sample purity and sources.…”

“…In addition, counter-current chromatography (CCC) [26], a unique liquid-liquid partition chromatography developed recently, needs off-line high performance liquid chromatography (HPLC) detection for every peak fraction. To determine the compounds in samples, the vast majority of analysis methods, performed by using thin-layer chromatography (TLC) scanning [19,20], UV absorption [21], normal-phase and reversed-phase high performance liquid chromatography (NP/RP-HPLC) [22][23][24][25], have less specificity and sensitivity among the compounds with similar structure.…”
