The Gunners, missing several players including injured England forward Beth Mead who has ruptured her ACL, fell behind early in the second-half when Lineth Beerensteyn slotted Juventus ahead following a swift counter attack.
Vivianne Miedema headed in from a corner to equalise just after the hour, but Jonas Eidevall’s side could not craft a late winner.
Arsenal, who had been looking to extend their 100 per cent start, stay top of Group C, two points clear of Juventus and three of Lyon, who won 3-0 away to Zurich.
The Gunners made a positive start, with Stina Blackstenius played through by Frida Maanum, but saw her rising shot skim the top of the crossbar.
Juventus goalkeeper Pauline Peyraud-Magnin, who spent a couple of seasons with the Gunners, then made fine save after Swedish forward Blackstenius was sent clear again shortly before the break. At the other end, Arianna Caruso put the ball wide in first-half stoppage time.
Arsenal pressed again early in the second half as Australian Caitlin Foord tested Peyraud-Magnin before Lotte Wubben-Moy’s header was cleared off the line.
But it was Juve who broke the deadlock in the 51st minute. Dutch forward Beerensteyn burst through on a counter-attack to slot past Arsenal keeper Manuela Zinsberger.
Arsenal responded and got the equaliser just after the hour mark when Miedema headed in from a corner, and while the forward went close to completing the comeback, both sides had to settle for a point.
