Ferroptosis, a novel form of regulated cell death, is characterized by oxidative injury from iron accumulation and lipid peroxidation. In a natural product library screening for ferroptosis inhibitor, we found that baicalein is a potent inhibitor of erastin-induced ferroptosis in pancreatic cancer cells. Baicalein (also termed 5,6,7-trihydroxyflavone) is a flavonoid originally obtained from the roots of Scutellaria baicalensis and Scutellaria lateriflora. We showed that baicalein exhibits remarkable anti-ferroptosis activity compared with well-known ferroptosis inhibitors such as ferrostatin-1, liproxstatin-1, deferoxamine mesylate, and β-mercaptoethanol...

Since many glycoside compounds in natural products are hydrolyzed by intestinal microbiota when administered orally, it is of interest to know whether their pharmacological effects are derived from the glycoside itself or from the aglycone form in vivo. An interesting example is baicalin versus baicalein, the aglycone of baicalin, which is contained in some herbs from Labiatae including Scutellaria baicalensis Georgi and Scutellaria lateriflora Linne. The herbs have been extensively used for treatment of inflammatory diseases in Asia...

Fibrosarcoma is an aggressive and highly metastatic cancer of the connective tissue, for which effective therapeutic methods are limited. Recently, there has been a renewed interest in small molecular compounds from natural products in the treatment of cancer. In the present study, we investigated the compound, scutellarein, extracted from the perennial herb Scutellaria lateriflora, and it was found to possess anticancer potential. Cell proliferation assay and cell cycle analysis revealed that the proliferation rate of HT1080 human fibrosarcoma cells was significantly suppressed by treatment with scutellarein through the induction of apoptosis...

Scutellaria lateriflora (American skullcap) has been used in traditional medicine to treat several medical conditions including nervous disorders and cancer. Previous studies have associated these medicinal properties to flavones present in roots and leaves of this species. In order to develop a production system and study the biosynthesis of these bioactive compounds, hairy root cultures of S. lateriflora were established and line 4 was selected for further studies based on its growth performance in a modified Murashige and Skoog's medium supplemented with 0...

Scutellaria lateriflora (skullcap) is a medicinal herb that has a long history of use in the treatment of ailments such as insomnia and anxiety. Commercial herbal formulations claiming to contain S. laterifolia herba have flooded the consumer markets. However, due to intentional or unintentional adulteration, cases of hepatotoxicity have been reported. Possible adulteration with the potentially hepatotoxic Teucrium spp., T. canadense and T. chamaedrys has been reported. In this study, hyperspectral imaging in combination with multivariate image analysis methods was used to differentiate S...

Scutellaria lateriflora (American skullcap), a native plant of North America, has been used by Americans and Europeans as a nerve tonic for more than 200 years. In vivo studies have shown anxiolytic activity ofS. lateriflora in animals and humans. However, the neuroprotective mechanisms ofS. lateriflora are not fully understood. Oxidative stress plays a vital role in the neurodegenerative and neuropsychiatric diseases such as anxiety, Alzheimer's disease, depression, and Parkinson's disease. Bioactive compounds present in various medicinal plants neutralize or scavenge toxic free radicals and thus suppress oxidative stress...

Baicalin, baicalein, and wogonin were accumulated in hairy roots derived from Scutellaria lateriflora and Scutellaria baicalensis. The levels of baicalein and baicalin were 6.8 and 5.0 times higher, respectively, in S. baicalensis than in S. lateriflora. A total of 47 metabolites were detected and identified in Scutellaria species by GC-TOF MS. The metabolites from the two species were subjected to principal component analysis (PCA) to evaluate differences. PCA fully distinguished between the two species. The results showed that individual phenolic acids and phenylalanine, precursors for the phenylpropanoid biosynthetic pathway, were higher in S...

Research in the area of herbal psychopharmacology has revealed a variety of promising medicines that may provide benefit in the treatment of general anxiety and specific anxiety disorders. However, a comprehensive review of plant-based anxiolytics has been absent to date. Thus, our aim was to provide a comprehensive narrative review of plant-based medicines that have clinical and/or preclinical evidence of anxiolytic activity. We present the article in two parts. In part one, we reviewed herbal medicines for which only preclinical investigations for anxiolytic activity have been performed...

Hairy root cultures of Scutellaria lateriflora were established using Agrobacterium rhizogenes A4 and produced acteoside (18.5 mg g(-1) dry wt), baicalin (14.5 mg g(-1) dry wt) and wogonoside (12 mg g(-1) dry wt). Yeast extract (50 μg ml(-1)) increased acteoside production 1.4-fold and flavone production 1.7-fold after 7 and 14 days of elicitation. Addition of Pectobacterium carotovorum lysate in the stationary phase of the hairy root culture stimulated only the accumulation of wogonin to 30 mg g(-1) dry wt...

MeOH extracts of 37 herbs were tested in screening experiments for rat intestinal alpha-glucosidase. The MeOH extract of the aerial parts of Scutellaria lateriflora L. (Lamiaceae) significantly inhibited sucrase and maltase activities, using sucrose and maltase as the substrates. Enzyme inhibition guided-fractionation of the MeOH extract of S. lateriflora resulted in the isolation of a new diterpene glucoside, deacetylajugarin-IV 18-O-beta-D-glucopyranoside (1), along with 20 known phenolics (2-21). The structures of 1-21 were elucidated on the basis of MS and NMR data analyses...

Transmissible spongiform encephalopathies (TSE) are characterized by the misfolding of the host encoded prion protein (PrP(C)) into a pathogenic isoform (PrP(Sc)) which leads to the accumulation of β-sheet-rich fibrils and subsequent loss of neurons and synaptic functions. Although many compounds have been identified which inhibit accumulation or dissolve fibrils and aggregates in vitro there is no therapeutic treatment to stop these progressive neurodegenerative diseases. Here we describe the effects of the traditional medicinal herb Scutellaria lateriflora (S...

Scutellaria lateriflora has been used more than 200 years as a mild relaxant and as a therapy for anxiety, nervous tension, and convulsions. Currently, it is one of the most popular botanicals with many products on the USA market. Flavonoids with anxiolytic property have been reported from the aerial parts of this plant. From the HPLC chromatogram of the methanolic extract of this plant, it can be concluded that some flavonoids have not been identified yet. In the present study a simple high-performance liquid chromatography with UV and electrospray ionization mass spectrometric detection (HPLC-DAD/ESI-MS(n)) method has been developed for the identification of major phenolic compounds from it...

Scutellaria lateriflora, commonly known as skullcap, is used as an ingredient in numerous herbal products. However, it has been occasionally adulterated/contaminated with Teucrium canadense and/or Teucrium chamaedrys, commonly known as germander, due to the morphological similarities between the two genera. The latter contains hepatotoxic diterpenes. Despite the potential hepatotoxicity introduced by germander contamination, analytical methodologies for the authentication and quality assessment of S. lateriflora-based dietary supplements have not been reported...

Research in the area of herbal psychopharmacology has increased markedly over the past decades. To date however, a comprehensive review of herbal antidepressant, anxiolytic and hypnotic psychopharmacology and applications in depression, anxiety and insomnia has been absent. A search of MEDLINE (PubMed), CINAHL, PsycINFO, and the Cochrane Library databases was conducted (up to February 21st 2011) on commonly used psychotropic herbal medicines. A review of the literature was conducted to ascertain mechanisms of action of these botanicals, in addition to a systematic review of controlled clinical trials for treatment of mood, anxiety and sleep disorders, which are common comorbid psychiatric disorders...

The study of medicinal plants has many unique challenges and special considerations. These plants are studied for their specific chemistry, or pharmacologic activity. Plants are highly sensitive to their environment and respond through changes in their chemistry. To date, one of the biggest problems in the study of medicinal plants has been the acquisition of consistent, positively identified material for chemical analysis. Successful protocols for the collection, identification, and establishment of medicinal plants species in tissue culture is invaluable for future studies...
