The biochemistry and medical significance of the flavonoids.

Morinda citrifolia L (Noni) has been used in folk remedies by Polynesians for over 2000 years, and is reported to have a broad range of therapeutic effects, including antibacterial, antiviral, antifungal, antitumor, antihelmin, analgesic, hypotensive, anti-inflammatory, and immune enhancing effects. In order to reveal the nutritional and medicinal value of the Noni plant, and to summarize scientific evidence that supports the Polynesians' claim, a literature review and recent advances in Noni research is given below.

Morinda citrifolia (Noni): a literature review and recent advances in Noni research.

Passiflora: a review update.

Labiatae family is well represented in Iran by 46 genera and 410 species and subspecies. Many members of this family are used in traditional and folk medicine. Also they are used as culinary and ornamental plants. There are no distinct references on the ethnobotany and ethnopharmacology of the family in Iran and most of the publications and documents related to the uses of these species are both in Persian and not comprehensive. In this article we reviewed all the available publication on this family. Also documentation from unpublished resources and ethnobotanical surveys has been included. Based on our literature search, out of the total number of the Labiatae family in Iran, 18% of the species are used for medicinal purposes. Leaves are the most used plant parts. Medicinal applications are classified into 13 main categories. A number of pharmacological and experimental studies have been reviewed, which confirm some of the traditional applications and also show the headline for future works on this family.

Behavioural effects of Passiflora incarnata L. and its indole alkaloid and flavonoid derivatives and maltol in the mouse

The traditional therapeutic indications for the use of Morinda citrifolia L. (Rubiaceae) have been investigated. The lyophilised aqueous extract of roots of M. citrifolia was evaluated for analgesic and behavioural effects in mice. The extract did not exhibit any toxic effects but did show a significant, dose-related, central analgesic activity in the writhing and hotplate tests; this effect was confirmed by the antagonistic action of naloxone. Furthermore, administration of M. citrifolia extract at high dosages decreased all behavioural parameters in the two compartment test, the light/dark choice situation test, and the staircase test; together with the induced sleeping time, these results are suggestive of sedative properties.

Eschsholzia californica Cham. is a traditional medicinal plant of the Indians used by the rural population of California for its analgesic and sedative properties. Our study on the aqueous extract shows that this plant reduced the behavioural parameters measured in a familiar environment test in mice (novelty preference, locomotion and rearings in two compartments test) at doses above 100 mg/kg and in non-familiar environment tests (staircase test) at doses above 200 mg/kg. This finding validates its traditional sedative properties confirmed by the sleeping induction at doses above 100 mg/kg. Furthermore, when administered at a dose a of 25 mg/kg, E. californica appeared to also have an anxiolytic action since it produced an increase of the number of steps climbed by mice in the staircase test (anticonflict effect) and that of the time spent by animals in the lit box when they were confronted with the light/dark choice situation. Before evaluation of the behavioural effects, it was verified that our aqueous extract did not induce any toxic effect when administered i.p. and p.o.

Behavioural effects of the American traditional plant Eschscholzia californica: sedative and anxiolytic properties.

A lyophilised hydroalcoholic extract of Melissa officinalis L. (Lamiaceae) has been evaluated for behavioral effects in mice. According to the traditional use of M. officinalis, sedative properties have been confirmed for low doses by the decrease of behavioral parameters measured in a non-familiar environment test (staircase test) and in a familiar environment test (two compartment test). With high doses, a peripheral analgesic activity was obtained by reducing the acetic acid-induced pain (writhing test); moreover, the plant extract induced the sleep in mice after treatment with an infrahypnotic dose of pentobarbital and potentialised the sleep induced by a hypnotic dose of pentobarbital.
