“…Biotechnological applications for the production of secondary metabolites using hairy root cultures of plants have been reported. Followings can be given as examples of secondary compounds produced from hairy roots: podophyllotoxin and related aryltretralin-lignans in Linum flavum , ( Mikac et al., 2021 ); curcumin and curcumin monoglucoside in Atropa belladonna ( Singh et al., 2021b ); feruloyl-glucoside in Turbinicarpus lophophoroides ( Solis-Castañeda et al., 2020 ); sapogenins (stigmasterol and hecogenin) in Chlorophytum borivilianum ( Bathoju et al, 2017 ); alkaloids including eburenine, quebrachamine, fluorocarpamine, pleiocarpamine, tubotaiwine, tetrahydroalstonine and ajmalicine in Rhazya stricta ( Akhgari et al., 2019 ); cryptotanshinone and tanshinone in Perovskia abrotanoides ( Ebrahimi et al., 2017 ); tropane alkaloids, atropine (hyosciamine) and scopolamine (hyoscine) in Atropa komarovii ( Banihashemi et al., 2017 ); flavonoids (rutin, quercetin, isorhamnetin, and isoliquiritigenin) in Isatis tinctoria ( Jiao et al., 2018 ); caffeic acid, prolithospermic acid, salvianolic acid J, rosmarinic acid hexoside (I) and (II), salvianolic acid E, methyl rosmarinate, salvianolic acid F (or isomer I and II) in Salvia viridis ( Grzegorczyk-Karolak et al., 2018 ); triterpenoids in Centella asiatica ( Baek et al., 2022 ) and taxol in Taxus baccata sub sp. wallichiana ( Sahai and Sinha, 2022 ).…”
