What Are Jujubosides A/B and Spinosin?
Jujubosides A, Jujubosides B, and spinosin are the three core active components derived from the dried mature seeds of Ziziphus jujuba Mill. var. spinosa, a plant of the Ziziphus genus in the Rhamnaceae family.
They also act as the key substances that determine the sedative, sleep-promoting, and stress-relieving effects of sour jujube seed and its extracts, with the levels of these components directly dictating the quality grade of Sour Jujube Seed Extract.
As a unique flavonoid C-glycoside, spinosin differs from common flavonoids: it not only improves sleep quality but also exhibits significant antioxidant and neuroprotective effects. Moreover, it can form a synergistic effect with jujubosides A and B, further enhancing the regulatory efficacy of Sour Jujube Seed Extract on sleep and stress-related issues.
How Does Sour Jujube Seed Extract Work for Sleep?

Improves difficulty falling asleep
The jujubosides A and B in Sour Jujube Seed Extract act like a key to turn on the “calming switch” in the brain, quickly calming an overactive mind. At the same time, they reduce the substances in the brain that keep us alert. Working in these two ways, they shorten the time it takes to fall asleep.
Enhances sleep quality
The jujubosides A and B and spinosin in the extract work together. Not only do they prolong the duration of deep sleep, but spinosin also helps stabilize sleep rhythms. Additionally, spinosin protects the sleep-regulating areas of the brain from damage, reducing the number of nighttime awakenings and the frequency of dreaming.
Regulates sleep rhythms
After staying up late, experiencing jet lag, or working shift hours, the body’s stress system becomes disrupted, causing stress hormone levels to stay abnormally high at night and throwing sleep rhythms off balance. Sour jujube seed extract can calm this disrupted stress system, lower the elevated nighttime stress hormone levels, and regulate the substances in the brain that control sleep rhythms, helping to gradually restore normalcy to disrupted sleep schedules.

How Does Sour Jujube Seed Extract Work for Stress?
Rapidly relieves acute stress and anxiety
The jujubosides A and B in Sour Jujube Seed Extract can directly inhibit the overactivation of the body’s stress regulation system and reduce the secretion of stress hormones—acting like hitting the brakes on an overactive stress system to quickly soothe discomforts such as irritability, nervousness, and palpitations. At the same time, they regulate the balance of neurotransmitters in the brain and reduce anxiety-inducing substances, helping emotions return to a calm state rapidly.
Improves fatigue and cognitive decline caused by chronic stress
Long-term stress produces a large number of harmful free radicals in the body, which damage the brain regions responsible for memory and mood regulation. Spinosin in the extract has strong antioxidant properties; it can scavenge these free radicals and protect brain nerve cells from damage. Additionally, it promotes the brain’s secretion of neurotrophic factors, enhancing the vitality of nerve cells, thereby alleviating issues such as fatigue, inattention, and impaired memory caused by chronic stress.
Enhances the body’s stress resilience and stabilizes mood
By continuously regulating the function of the HPA axis, the extract prevents the body from having excessive stress responses when facing pressure, reducing stress-induced mood swings (such as irritability and low mood). It also synergistically regulates the balance of neurotransmitters, helping the body establish a more stable mood regulation mechanism. Long-term use can enhance the body’s overall stress resilience potential, making people less likely to be overwhelmed by pressure.
