TL;DR: Sargassum swartzii was studied for antioxidant potential in this paper, where sulfated polysaccharide extracted from the brown algae Sargasso swartzi was used.

TL;DR: The present review focuses on the lead compound, that is, podophyllotoxin and summarizes its structural characteristics, natural sources, biological activities, novel derivatives, medicinal applications and future perspectives.

TL;DR: This preliminary screening of fungal endophytes revealed their potential to yield potent bioactive compounds for drug discovery programmes.

TL;DR: Nine compounds, among them compounds 1-3, 5-8 were found from this plant for the first time, and their structures were elucidated on the basis of spectroscopic analysis.

TL;DR: Findings indicate that Achillea millefolium inflorescence aqueous extract may be partially protective against CP-induced testicular toxicity.

TL;DR: Compounds 2 and 9 are reported from A. bidentata for the first time and are a new feruloyl tyramine glycoside and triterpenoid saponins respectively.

TL;DR: Seventeen compounds isolated from ethanol extract of S. suberectus Dunn were isolated from the Spatholobus genus for the first time and were characterized based on their physical characteristics and spectra data.

TL;DR: The present review summarizes the list of plant material, and their isolated phytoconstituents which have been tested for their AR inhibitory activity, and covers the period to 2011, and a total of 72 plants are listed.

TL;DR: In this paper, the antioxidant activity of Garcinia xanthochymus leaf, root and fruit extracts in vitro was investigated by determining the total phenolic content, evaluating the reducing power, measuring the capability for scavenging free radicals, as well as its ability to inhibit DNA cleavage, using appropriate assay systems.

TL;DR: All processing procedure, including fermentation, might reduce the anti-oxidative activity of Polygoni Multiflori Radix (PMR), however, most of the processed products could lessen the adverse effect on gastrointestinal tract compared to PMR.

TL;DR: In this article, the chemical constituents from the stems of Celastrus orbiculatus Thunb were investigated and their structures were elucidated on the basis of physical characteristics and spectral data.

TL;DR: The results indicate that the extracts of Achillea millifolium are effective in hyperglycemia and can effectively protect against other metabolic aberrations caused by alloxan monohydrate.

TL;DR: In this article, the chemical constituents from the bran of Avena sativa Linn were identified and their structures were elucidated by physicochemical properties and spectroscopic data.

TL;DR: Both extracts showed significant and dose-dependent anti-inflammatory and anti-arthritic effects compared to control group, suggesting that extracts of P. sajorcaju can be used against inflammatory and autoimmune disease.

TL;DR: In this article, a novel ultrasonic assisted aqueous extraction process was optimized and orthogonally designed to pave the way for replacing the toxic organic solvent, methanol with water.

TL;DR: In vitro bioactive assays including antifungal activity against three human pathogenic fungi Microsporum canis, Tricophyton rubrum and Epidermophyton floccosom and cytotoxic activity against the human nasopharyngeal epidermoid tumor KB cell line were evaluated.

TL;DR: In this paper, a high performance liquid chromatography-diode array detection-electrospray ionization tandem mass spectrometry (HPLC-DAD-MS/MS) method was established for the characterization and quantification of multi-constituents in Aurantii Fructus Immaturus extracts.

TL;DR: In this paper, the chemical constituents from the seeds of Millettia pachycarpa were investigated and their structures were elucidated on the basis of spectroscopic analyses, and their cytotoxic activities against human tumor cell lines (7860, A549, A2780, Hela, K562) and murine tumor cell line (LL/2, B16) were evaluated by MTT assay.

TL;DR: The minimum bactericidal concentration (MBC) indicated that the bactericidal activities of 1 occurred at concentrations higher than its growth inhibitory concentrations, and clearly demonstrated the in vitro bactericidal effect of 1 against S. aureus and S. epidermidis.

TL;DR: In this paper, the chemical constituents in the roots of Euphorbia fischeriana were identified on the basis of spectroscopic analyses and physiochemical properties using various chromatographic techniques.

TL;DR: The MeTD at 500 mg·kg(-1), p.o. was found to possess significant estrogenic activity and the results are in consistent with the literature reports related to anti-fertility effect of flower extracts of Tabernaemontana divaricata.

TL;DR: In this article, the chemical constituents of Hericium erinaceums (Hericiaceae) were isolated using silica gel column chromatography and preparative HPLC, and their structures were elucidated on their basis of the spectral data.

TL;DR: In this article, the sesquiterpene lactones from Vernonia bockiana were used as antitumor agents against the human leukemic cell line HL-60.
