Simultaneous determination of nine phenolic compounds in imitation wild samples using ultrahigh-performance liquid chromatography-tandem mass spectrometry.

Kimura et Migo (), one of the nine everlasting types of grass, has gained increasing attention owing to its important roles in alternative medicines and drug discovery. Due to its natural resources being in danger of being extinct, imitation wild planting is becoming increasingly common. To assess the product's quality completely, an efficient ultrahigh performance liquid chromatography-triple quadrupole tandem mass spectrometry (UHPLC-QQQ-MS/MS) method was established to simultaneously quantify nine phenolic compounds in samples.

Lignans from the genus Piper L. and their pharmacological activities: An updated review.

The genus Piper, a member of the Piperaceae family, comprises >2000 species, of which many are well known to possess considerable economic and medicinal values. Lignans are essential ingredients and are rich in Piper plants. Although many phytochemical studies have reported many lignans identified from Piper plants, comprehensive research has not reviewed these compounds.
