Eleutheroside E1 is a bioactive phenylpropanoid glycoside and one of the key marker compounds found in Eleutherococcus senticosus (commonly known as Siberian ginseng), a woody shrub native to Northeast Asia. Unlike true ginseng (Panax ginseng), Siberian ginseng contains eleutherosides rather than ginsenosides—distinct chemical markers with adaptogenic properties.
Eleutheroside E1, along with Eleutherosides B and E, is used as a standardization marker for Siberian ginseng extracts, ensuring consistent adaptogenic activity. It is distinct from Eleutheroside E (CAS 39432-56-9)—note the “1” designation indicates a specific isomer or purified fraction.

| Composto | N. CAS. | Role in Adaptogen Activity |
|---|---|---|
| Eleutheroside B (Syringin) | 118-34-3 | Anti-fatigue, immune modulation |
| Eleutheroside E | 39432-56-9 | Stress resistance, neuroprotection |
| Eleuteroside E1 | 7374-79-0 | Adaptogenic activity marker |
| Eleutheroside I | 114592-29-9 | Supporto immunitario |
Note: Eleutheroside E1 is a purified marker compound, primarily used for analytical reference, standardization, and research applications. For commercial nutraceutical formulations, standardized Siberian ginseng extract (containing a defined profile of eleutherosides) is typically used rather than the isolated single compound.
LyvBio S.r.l. supplies both pure Eleutheroside E1 (analytical grade) and standardized Siberian ginseng extract (commercial grade).

Q: What is the difference between Eleutheroside E1 and Eleutheroside E?
A: They are distinct compounds with different molecular weights and structures. Eleutheroside E (CAS 39432-56-9, MW 742.72) is a dimeric lignan glycoside. Eleutheroside E1 (CAS 7374-79-0, MW 580.58) is a different marker compound. Both are found in Siberian ginseng.
Q: Is Eleutheroside E1 the same as Siberian ginseng?
A: No. Siberian ginseng (Eleutherococcus senticosus) contains multiple bioactive compounds, including eleutherosides B, E, E1, I, and others. Eleutheroside E1 is just one marker compound.
Q: Should I use pure Eleutheroside E1 or standardized extract for my supplement?
A: For finished nutraceutical products, use standardized Siberian ginseng extract (e.g., ≥1% total eleutherosides). Pure Eleutheroside E1 is for analytical reference, research, or standardization purposes only.
Q: What is the typical eleutheroside content for extract standardization?
A: Common specifications: total eleutherosides ≥0.8–1.5% (HPLC), with Eleutheroside B ≥0.2% and Eleutheroside E ≥0.4%.
Q: Can Siberian ginseng be taken daily?
A: Yes, but cyclical use (e.g., 8 weeks on, 1–2 weeks off) is traditionally recommended for optimal adaptogenic effects and to prevent tolerance.
Q: What is your MOQ for pure Eleutheroside E1?
A: Research samples: 100mg–500mg. Bulk: 5g+. Lead time: 3–5 days (samples); 10–15 days (bulk).
Q: What is your MOQ for standardized Siberian ginseng extract?
A: Sample orders: 1kg. Trial production: 5–25 kg. Commercial: Negotiable. Lead time: 3–5 days (samples); 10–15 days (bulk).
