The Crystal Structure of 3-(4′-Methoxyphenyl)propanoyl pyrrole of Piper lolot C.DC from Vietnam

Xanthine oxidase, α-glucosidase and α-amylase inhibitory activities of the essential oil from Piper lolot: In vitro and in silico studies

“…The whole plant of P. lolot has been used as a traditional medicine to treat toothache, headache, diarrhea, rheumatism, lumbago, purulent rhinitis, and digestive disorders [ 7 ]. Previous phytochemical investigations of this species have led to the isolation of amide alkaloids, phenanthrene-type alkaloids, steroids, chalcones, amides, benzenoids, and ionones [ [8] , [9] , [10] , [11] , [12] ]. Furthermore, pharmacological studies on extracts from P. lolot showed anti-platelet [ 8 ], anti-inflammatory [ 9 ], anti-diabetic [ 10 ], and anti-oxidant [ 11 ] activities.…”

Isolation and Identification of Antiplatelet Aggregatory Principles from the Leaves of Piper lolot

“…Piper species have been extensively investigated as a source of new natural products with potential antitumoral, antimicrobial, antifungal, antiplatelet aggregation, and insecticidal activities – . The phytochemical profile in Piper species is characterized by the production of typical classes of compounds such as amides, alkaloids, benzoic acids, lignans, neolignans, and a few flavones and chalcones – , – . P. lolot is a small shrub found widely at lower elevations in Vietnam and often used to flavor meat in Southeast Asian dishes.…”

“…P. lolot is a small shrub found widely at lower elevations in Vietnam and often used to flavor meat in Southeast Asian dishes. It has been used to treat various diseases such as rheumatism, lumbago, digestive troubles, vomiting, diarrhea, and others , . This species has not been the subject of thorough phytochemical analysis, and a methanolic extract of the leaves showed sufficient potent inhibitory activity on platelet aggregation induced by arachidonic acid (AA) and platelet activating factor (PAF) to warrant bioassay-guided fractionation.…”
