Plants are still a source in nature to obtain and isolate molecules with pharmacological applications (drug discovery), but can also be used as herbal medicinal products in traditional or complementary medicine.In addition, the WHO has launched a Traditional Medicine Strategy (2014-2023), including herbal medicines as medicinal therapies, with the aim to ensure the quality, safety, proper use, and effectiveness of traditional medicines, among other objectives.This is a reprint of articles from the Special Issue on "Bioactivity of Medicinal Plants and Extracts" published online in the open access journal Biology. This reprint includes a collection of original research and review articles on new advances in the development and application of bioactive compounds and extracts from plant matrices. 606 $aChemistry$xStudy and teaching 606 $aBiomedical engineering 615 0$aChemistry$xStudy and teaching. 615 0$aBiomedical engineering. 676 $a540.71 700 $aLes$b Francisco$01369479 702 $aCa?sedas$b Guillermo 702 $aLo?pez$b Vi?ctor 801 0$bNjHacI 801 1$bNjHacl 906 $aBOOK 912 $a9910674015303321 996 $aBioactivity of Medicinal Plants and Extracts$93395605 997 $aUNINA LEADER 05607nam 22007814a 450 001 9911019095303321 005 20200520144314.0 010 $a9786610238927 010 $a9780470869666 010 $a0470869666 010 $a9780470491232 010 $a047049123X 010 $a9780471498483 010 $a0471498483 010 $a9781280238925 010 $a1280238925 035 $a(CKB)3520000000000212 035 $a(EBL)239026 035 $a(OCoLC)475950094 035 $a(SSID)ssj0000120565 035 $a(PQKBManifestationID)11130177 035 $a(PQKBTitleCode)TC0000120565 035 $a(PQKBWorkID)10092490 035 $a(PQKB)11297035 035 $a(MiAaPQ)EBC239026 035 $a(Perlego)2755388 035 $a(EXLCZ)993520000000000212 100 $a20030416d2004 uy 0 101 0 $aeng 135 $aur|n|---||||| 181 $ctxt 182 $cc 183 $acr 200 10$aChemistry in alternative reaction media /$fDave J.
