Besides bornyl caffeate (1, already been reported by us previously), bioassay-guided fractionation resulted in two additional cinnamic acid derivatives 2\u20133 with moderate leishmanicidal activity. The structure of a novel nepetolactone derivative 4 having a cinnamic acid moiety was elucidated by means of spectral analysis. To the best of our knowledge villoside aglycone (5) was isolated from this plant for the first time. The bioassay-guided fractionation yielded two new (compounds 6\u20137) and two known valtrates (compounds 8\u20139) with leishmanicidal potential against Leishmania major (L. major) promastigotes. In addition, \u03b2-bisabolol (10), \u03b1-kessyl alcohol (11), valeranone (12), bornyl isovalerate (13) and linarin-2-O-methylbutyrate (14) were identified. This is the first report on the isolation of 4'-demethylpodophyllotoxin (15), podophyllotoxin (16) and pinoresinol (17) in V. wallichii. In total thirteen known and four new compounds were identified from the extract and their cytotoxic and antileishmanial properties were evaluated.<\/jats:p>","DOI":"10.3390\/molecules20045740","type":"journal-article","created":{"date-parts":[[2015,4,7]],"date-time":"2015-04-07T03:47:46Z","timestamp":1428378466000},"page":"5740-5753","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":44,"title":["Antileishmanial and Cytotoxic Compounds from Valeriana wallichii and Identification of a Novel Nepetolactone Derivative"],"prefix":"10.3390","volume":"20","author":[{"given":"Jan","family":"Glaser","sequence":"first","affiliation":[{"name":"Institute of Pharmacy and Food Chemistry, University of Wuerzburg, Am Hubland,  97074 Wuerzburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martina","family":"Schultheis","sequence":"additional","affiliation":[{"name":"Institute for Molecular Infection Biology, University of Wuerzburg, Josef-Schneider-Str. 2,  97080 Wuerzburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heidrun","family":"Moll","sequence":"additional","affiliation":[{"name":"Institute for Molecular Infection Biology, University of Wuerzburg, Josef-Schneider-Str. 2,  97080 Wuerzburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Banasri","family":"Hazra","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Technology, Jadavpur University, Kolkata-700032, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ulrike","family":"Holzgrabe","sequence":"additional","affiliation":[{"name":"Institute of Pharmacy and Food Chemistry, University of Wuerzburg, Am Hubland,  97074 Wuerzburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2015,4,1]]},"reference":[{"key":"ref_1","first-page":"2337","article-title":"Valeriana wallichii: A phyto-pharmacological review","volume":"3","author":"Sah","year":"2010","journal-title":"J.
