Iridoid Glucosides with Free Radical Scavenging Properties from Fagraea blumei
Four new iridoid glucosides 1–4, named blumeosides A–D, were isolated from the methanolic stem-bark extract of Fagraea blumei G. DON. (Loganiaceae). They were accompanied by the benzyl-alcoholExpand
Goji (Lycium barbarum and L. chinense): Phytochemistry, pharmacology and safety in the perspective of traditional uses and recent popularity.
In view of the available pharmacological data and the long tradition of use in the traditional Chinese medicine, L. barbarum and L. chinense certainly deserve further investigation, but clinical evidences and rigorous procedures for quality control are indispensable before any recommendation of use can be made for Goji products.

Marine actinomycetes as a source of novel secondary metabolites
New marine members of the rare genus Verrucosispora seem to be a promising source for novel bioactive secondary metabolites as shown in the case of the abyssomicin producing strain AB-18-032. Expand
Morinda citrifolia (Noni) fruit--phytochemistry, pharmacology, safety.
Current knowledge on the phytochemistry, pharmacology, safety aspects of Noni fruit and Noni-derived products, and health-related claims and benefits is reviewed. Expand
Antibacterial phloroglucinols and flavonoids from Hypericum brasiliense.
Four phloroglucinols have been isolated from a petrol extract of the leaves and flowers of Hypericum brasiliense and were antibacterial against Bacillus subtilis in a TLC bioautographic assay. Expand
Ethnobotanical survey on wild alpine food plants in Lower and Central Valais (Switzerland).
This study provides for the first time comprehensive data on present day and historical uses of wild plants as food in Lower and Central Valais and can be used to identify species which may provide interesting opportunities for diversification of mountain agriculture. Expand
Identification of TLC markers and quantification by HPLC-MS of various constituents in noni fruit powder and commercial noni-derived products.
The composition of noni (Morinda citrifolia) products has been investigated and a method for the quantification of characteristic noni constituents, such as iridoid glucosides, scopoletin, rutin, fatty acid glucoside, and anthraquinones, was developed and validated. Expand
Antioxidant and lipophilic constituents of Tinospora crispa.
Three compounds exhibiting antioxidant and radical scavenging properties towards beta-carotene and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical proved to be more active than the synthetic antioxidant butylhydroxytoluene (BHT). Expand
Anti-inflammatory and antiallergic activity in vivo of lipophilic Isatis tinctoria extracts and tryptanthrin.
The effects of a supercritical CO2 (SFE) extract, a dichloromethane (DCM) extract from Isatis tinctoria leaf and the alkaloidal constituent tryptanthrin were studied in acute and subchronicExpand
