Three Piper species, Piper longum, P. ribesoides and P. sarmentosum, were selected for investigation of adulticidal potential against Stegomyia aegypti, a main vector of dengue and dengue haemorrhagic fever. Successive extraction by maceration with 95% ethanol showed percentage yields of ethanolic
Tropical and subtropical plants are rich in endophytic community diversity. Endophytes, mainly fungi and bacteria, inhabit the healthy plant tissues without causing any damage to the hosts. These fungi can be useful for biological control of pathogens and plant growth promotion. Some plants of the
The repellent activity of Piper aduncum essential oil against Aedes albopictus was investigated under laboratory conditions with human volunteers. The lowest median effective dose (ED50) value was 1.5 microg/cm2 at 60 sec of exposure when compared to 90 sec (2.1 microg/cm2) and 120 sec (1.8
OBJECTIVE
To determine the gastroprotective and antisecretory effect of ethanol extract from matico leaves (Piper aduncum) in animal models.
METHODS
To evaluate the gastroprotective effect, 220 mice of the Balb C57 strain were used. They were randomized in 22 groups of ten animals each, in which the
The pharmacological activities of the water extract of Piper marginatum Jacq. (Piperaceae), a plant reputed in the Brazilian folk medicine for its analgesic/antiinflammatory, hemostatic and skin wound-healing properties, were assessed. Intraperitoneal injection (i. p.) of the extract (0.1 to 1 g/kg)
Piplartine {5,6-dihydro-1-[1-oxo-3-(3,4,5-trimethoxyphenyl)-2-propenyl]-2(1H)pyridinone} and piperine {1-5-(1,3)-benzodioxol-5-yl)-1-oxo-2,4-pentadienyl]piperidine} are alkaloid amides isolated from Piper. Both have been reported to show cytotoxic activity towards several tumor cell lines. In the
Piper longum, commonly referred as 'Pippali', has found its traditional use in India, Malaysia, Singapore and other South Asian countries as an analgesic, carminative, anti-diarrhoeic, immunostimulant, post childbirth to check postpartum hemorrhage and to treat asthma, insomnia, In Colombia, the only authorized treatment to cure snakebite envenomation is with the use of antivenom. The antivenom neutralizes the systemic effects properly, but is not very effective at neutralizing local effects, thus several cases have lead to complications. On the other hand, BACKGROUND
Piper longum L. fruits have been traditionally used against snakebites in north-eastern and southern region of India.
OBJECTIVE
To examine the ability of ethanolic extract of fruits of Piper longum L., Piperaceae (PLE) and piperine, one of the main active principles of Piper longum, to
Thirty-one of 75 extracts of plants used by traditional healers for snakebites, had moderate or high neutralizing ability against the haemorrhagic effect of Bothrops atrox venom from Antioquia and Chocó, north-western Colombia. After preincubation of several doses of every extract (7.8-4000
BACKGROUND
Different systems of traditional medicine of the Indian subcontinent, have used Acacia chundra Willd, Adhatoda vasica Nees., Mimusops elengi L., Piper nigrum L., Pongamia pinnata L. Pirerre, Quercus infectoria Olivier., Syzygium aromaticum L., Terminalia chebula Retz., Zingiber officinale
BACKGROUND
Inflammatory bowel disease (IBD) is associated with chronic inflammation of the intestinal tract. Piperine (1-peperoylpiperidine), the primary lipophilic component in black pepper (Piper nigrum) and long pepper (Piper longum), has been reported to be effective for anti-inflammatory.
BACKGROUND
Piperine, a main component of Piper longum Linn. and Piper nigrum Linn., is a plant alkaloid with a long history of medicinal use. Piperine exhibits antidepressant, hepatoprotective, anti-metastatic, anti-thyroid, immunomodulatory, antitumor and anti-inflammatory activities, However its
Piperlonguminine (PL), an important component of Piper longum fruits, is known to exhibit anti-hyperlipidemic, anti-platelet and anti-melanogenic activities. Here, the anticoagulant activities of PL were examined by monitoring activated-partial-thromboplastin-time (aPTT), prothrombin-time (PT), and
BACKGROUND
Serious side effects such as gastric intestinal ulcer, bleeding etc. are associated with most of the antiinflammatory and analgesic drugs. So, there is a need to search novel, potent, and safer antiinflammatory and analgesic drug.
METHODS
Based on "biology-oriented synthesis approach",
