In addition, their inhibitory activity on NO production and cytotoxic effects against human embryonic kidney cells (HEK-293A) and human hepatocellular carcinoma (HepG2) were evaluated. This is the first study of the phytochemical investigation of P. ginseng sprouts cultivated in Vietnam and ginseng sprouts also contained the same main active ginsenosides as in the 4–6-year old roots.

The present study investigated the phytochemical and biological properties of the rhizomes C. aromatica. From the CHCl3 extract of C. aromatic rhizomes, six known compounds, including (-)-hannokinol, (3R,5R)-3,5-diacetoxy-1,7-bis(4- hydroxyphenyl)heptane, naringenin, 2-(4- (hydroxymethyl)phenyl)propan-2-ol, 5-hydroxymethylfurfural, and bisacurone, were isolated. All compounds were tested on the biological inhibitory activities against tyrosinase, αglucosidase, and urease. It was the first time all compounds were isolated from rhizomes of C. aromatica Salisb.

This study was conducted to investigate the potential of phytochemical extracts on extending the shelf-life of harvested tomato fruits, and to determine which phytochemical extracts can best enhance its shelf-life. The free radical scavenging activity (FRSA) of tomato fruits coated with phytochemical extracts stored under ambient condition and the toxicity of the phytochemical coatings was also evaluated.

A phytochemical investigation on the ethanolic (EtOH) extract of the Vietnamese Curcuma longa (C. longa) rhizomes has led to the isolation of four curcuminoids including curcumin (1), demethoxycurcumin (2), bisdemethoxycurcumin (3), and cyclocurcumin (4). The chemical structure of compounds 1-4 was elucidated by Nuclear magnetic resonance (NMR) and Mass spectrometry (MS) spectral data.

In our current phytochemical investigation on the Tunisian plant Lycium arabicum Schweinf. ex Boiss., we attempted to explore the oil obtained from its fruits. This oil was extracted by cold maceration with ethanol and was analyzed to estimate its sterol and fatty acid content. The physicochemical parameters of the oil were also examined. They were specified in terms of acid value (0.8 ± 0.01 mg KOH g–1 oil), peroxide value (10.9 ± 0.02 meq O2 kg–1 oil), saponification value (162.97 ± 0.03 mg KOH g–1 oil), chlorophylls (1.011 ± 0.03 mg kg–1 oil) and carotenoids (42.1 ± 0.05mg kg–1 oil).

Onosma L., the largest genus of Boraginaceae, is represented by 105 species in Turkey with an endemism rate of 52%. Phytochemical studies indicate that Boraginaceae plants mainly comprise naphthoquinones with a wide range of biological activities including anticancer, antiinflammatory, wound healing, and antioxidant effects. However, few taxa of the genus Onosma have been investigated in detail for their bioactivities.

The present study intended to investigate the effect of aqueous extract from Calotropis procera L. on growth of wheat (Triticum aestivum L.), barley (Hordeum vulgare L.) and some pathogenic microorganisms (Escherichia coli L. and Staphylococcus aureus R.) by the laboratory experiments. Also, phytochemical screening of aqueous extract of C. procera was qualitatively tested for the presence of some bioactive compounds (alkaloids, phenolics, flavonoids, tannins, saponins, sterols and terpenoids).

The crude extract was obtained from the dried lichen powder's extraction at room temperature. The n-hexane, n-hexane-ethyl acetate, and ethyl acetate extracts were obtained by the liquid-liquid partition method. The organic compounds were isolated from n-hexane extract by silica gel and Sephadex LH-20 column chromatography. Their chemical structures were identified by the NMR and HR-ESI-MS data analysis and the comparison of their NMR data with the published data.
