Sturgeon has said she was not aware that Murrell had purchased many of the high-value items listed in court documents.
The former first minister added that she had no reason to believe that Murrell had not used his own money for any items he bought for her.
Sturgeon – who had stepped down as first minister in March 2023 – was arrested In June 2023 but was later told that she was no longer under investigation.
The former first minister announced last year that the pair were ending their marriage.
Responding to Murrell’s sentencing, her lawyer Aamer Anwar said his client “remains angry, hurt and distressed” by Murrell’s crimes.
He said Sturgeon was “utterly deceived and let down by her husband whom she had trusted” and that his actions were “beyond her comprehension”.
Anwar reiterated that the ex-SNP leader was not charged after a “robust” police investigation.
First Minister John Swinney, who appointed Murrell in 2001 during his first spell as SNP leader, has apologised to party members.
However, he has denied any attempts to shut down concerns about party finances.
After the sentencing, the SNP leader told reporters at Holyrood: “I was not a serving office bearer in the Scottish National Party from 2004 to 2024, so I had no operational right to look at these things.
“But is it distressing? Is it hurtful? Is it agony? Yes, all of those things.”
He said that he was focused on ensuring that the SNP “operates with clear and effective governance that protects the interests of the party”.
