Oxiranylphenyl esters from Pimpinella diversifolia

Studies on the Biosynthesis of Pseudoisoeugenols in Tissue Cultures of Pimpinella anisum

“…In a previous paper we reported the occurrence of several unusually substituted phenylpropanoids in three Pimpinella species which we called pseudoisoeugenols [1], Other authors independently found the same class of compounds in different Pimpinella species and thus confirmed our results [2]. The unusual 2,5-dioxy substitution pattern of the pseudoisoeugenols is not consistent with the normally assumed phenylpropanoid pathway and requires its own explanation.…”

Synthesis and GC–MS analysis of angelates and tiglates as an aid to identification of these components in essential oils

“…[1][2][3] The importance of the relative intensities of m/z 82 and 83 as well as 100 and 101 peaks in their mass spectra has been applied towards the diff erentiation of angelates from tiglates. [4] This method seems to be satisfactory primarily in distinguishing lower molecular weight angelates from tiglates.…”

Effect of essential oils and isolated compounds from Pimpinella species on NF‐κB: a target for antiinflammatory therapy

“…In the Himalayas, the ethanol extract of P. diversifolia DC. seeds, has been reported to be a strong fungitoxic and the extract of the whole plant has been found to possess spermicidal activity in rat semen (Bottini et al, 1986). The hot aqueous extract of the root of P. tirupatiensis Balakr.…”
