“…Flavonoids, coumarins (Awad 1994) and alkaloids (Lan, Dongming, Wei, Rufeng, Yi & Lijun 2005) have been reported to be important chemical constituents of this plant. In particular, it contains dopamine, dopa and a high concentration of noradrenaline (Feng, Haynes & Magnus 1961). It exhibits a wide range of pharmacological effects, including antibacterial (Zhang, Ji, Qu, Xia & Wang 2002), analgesic, anti‐inflammatory (Chen & Ainsworth 1992), skeletal musclerelaxant (Parry, Marks & Okwuasaba 1993) and wound‐healing activities (Rashed, Afifi & Disi 2003).…”

Qompsell are extracts of several traditional Chinese medicines: Astragalus membranaceus, Portulaca oleracea L, Flavescent sophora and Andrographis paniculata, etc. The macrophage phagocytic activity, macrophage ROS (reactive oxygen species), activity of serum lysozyme, SOD (superoxide dismutase), NOS (nitric oxide synthetase) and levels of total serum protein, globulin, and albumin were measured in carp that had been fed diets containing Qompsell at 0.3 g kg−1 for 60 days. The results showed that Qompsell had increased the macrophage phagocytic activity, macrophage ROS and the content of total protein, globulin, lysozyme in serum significantly (P<0.05). Also, the triglyceride and cholesterol levels had slightly increased but there was no significant difference. However, NOS, SOD and albumin showed no significant difference (P>0.05). These results indicate that the Qompsell formula might elevate the immunity function of carp (Cyprinus carpio).

“…It is also consumed as a vegetable, widely sold in shops in United Arab Emirates and Oman (Miller and Morris, 1988) and has been reported to be rich in α-linolenic acid and β-carotene (Liu et al, 2000;Barbosa-Filho et al, 2008). In addition to fl avonoids, coumarins (Awad, 1994) and monoterpene glycoside (Sakai et al, 1996), in particular, it contains N-trans-feruloyltyramine (Mizutani et al, 1998), dopamine, dopa, high concentration of noradrenaline (Feng et al, 1961), ferulic acid (Chen, 2000) and adenosine (Meng et al, 1981).…”

A sensitive and accurate high-performance thin-layer chromatographic method has been developed, validated, and used for quantification of dopamine in dried whole-plant powder of Portulaca oleracea Linn. The powder was extracted with 0.1 M HCl and the extract was separated on aluminum HPTLC plates coated with silica gel 60 F 254 , with n-butanol-glacial acetic acid-distilled water 7.0:2.0:1.0 (v/v) as mobile phase. Detection and quantitation were performed by densitometry, with a deuterium lamp, at 280 nm. The response to dopamine reference standard was linear in the concentration range 45.0 to 110.0 μg cm -3 . The validated method was used for quantitative analysis of dopamine in Portulaca oleracea Linn and can be used for routine quality-control analysis of whole-plant powder of Portulaca oleracea Linn.
