HPLC laboratory analysis of saffron extract

Saffracin™

Saffron (Crocus sativus L.) stigma extract, crocins standardized to 35.0 to 37.0% by HPLC

Saffracin saffron extract

What is it made from?

Saffracin™ is an ingredient extracted solely from the stigma of saffron (Crocus sativus L.). Each saffron flower yields only three stigma threads, so about 150,000 flowers are needed to obtain 1 kg of dried raw material.

The content of crocin and safranal, the representative active compounds of saffron, is measured by HPLC (high-performance liquid chromatography) and standardized so that each batch maintains consistent levels.

Ethanol and water are used as extraction solvents, and the finished product is supplied as a fine reddish-brown powder. The detailed extraction process is protected as a trade secret of the manufacturing partner.

Used in a marketed product

Saffracin™ is the raw material of ATTENSAF®, a 10 mg capsule (60 per bottle) marketed in Iran since February 2022.

Key active compounds

Saffron contains more than 150 compounds. Saffracin™ uses the following three as its standardization markers

CROCIN

Crocin

A carotenoid glycoside that gives saffron its red color and accounts for a substantial share of saffron’s weight, making it the representative marker compound. Saffracin™ is standardized to 35.0 to 37.0%.

SAFRANAL

Safranal

A volatile monoterpene aldehyde that gives saffron its characteristic aroma. It forms when picrocrocin breaks down during drying and processing, and Saffracin™ is specified at 0.10% or higher.

PICROCROCIN

Picrocrocin

A glycoside that gives saffron its bitter taste and acts as a precursor of safranal. It is monitored as a reference marker during quality control.

Every lot ships with a Certificate of Analysis.

Clinical evidence

Saffron extract has been studied in 15 clinical trials published in 16 peer-reviewed papers. The trials were led by Prof. Shahin Akhondzadeh’s group at Tehran University of Medical Sciences (TUMS).

15clinical trials
16peer-reviewed papers
750+randomized participants
7indications

Indications: ADHD, depression, Alzheimer’s disease, premenstrual syndrome, sexual dysfunction, type 2 diabetes and menopausal depression. Samanik has confirmed in a signed statement (L07-R2, 20 October 2026) that all 16 papers were conducted with Saffracin™, and Prof. Akhondzadeh has confirmed in writing that the study extract was supplied by Samanik. Most trials were small, and none was designed to prove equivalence.

Clinical dose and Saffracin™

Seven papers state the crocin content of the study capsules. Their dose of two 15 mg capsules a day contains about 3.4 mg of crocins (1.65 to 1.75 mg per capsule).

3.4 mgcrocins a day in the trial dose
9 to 10 mgof Saffracin™ a day gives the same crocins (at 36.1% crocins)
12xless extract than a 3% crocin extract, which needs about 113 mg a day

One 10 mg capsule covers the trial dose. The other nine papers do not state crocin content, so their doses (20 to 60 mg a day) are quoted as printed in each paper.

These were small trials and not equivalence tests. Reported side-effect rates of 8% versus 20% in Baziar 2019 were not tested for significance.

ADHD

Two ADHD trials: a direct comparison in children and an add-on trial in adults.

Baziar et al., 2019

J Child Adolesc Psychopharmacol. Children 6 to 17, 54 randomized, 6 weeks.

Double-blind pilot. Saffracin™ 20 to 30 mg a day versus methylphenidate 20 to 30 mg a day. Response rate 100% versus 96%. Parent-rated total score: no significant difference (p=0.975). Reported side effects 8% versus 20%, not tested for significance.

Pazoki et al., 2022

Adv Integr Med. Adults, 56 randomized, 6 weeks.

Placebo-controlled add-on trial. Methylphenidate 30 mg plus Saffracin™ 30 mg versus methylphenidate plus placebo. The ASRS score fell by 21.1 versus 15.9 points (p=0.024).

Doses are as stated in the papers. Neither paper states crocin content.
