FlavScents AInsights Entry: Lithospermum Officinale Extract (CAS: 90063-58-4)
1. Identity & Chemical Information
Lithospermum officinale extract, also known as gromwell root extract, is a natural complex material derived from the roots of the Lithospermum officinale plant. This extract is characterized by its complex mixture of bioactive compounds rather than a single molecular entity. The CAS number for this extract is 90063-58-4. It does not have a specific FEMA number or other identifiers such as FL or CoE numbers due to its complex nature. The composition of Lithospermum officinale extract can vary significantly depending on the geographical origin, harvest time, and processing methods used.

2. Sensory Profile
Lithospermum officinale extract is known for its subtle, earthy aroma with a hint of sweetness. The odor intensity is generally mild, making it suitable for use as a background note in fragrance compositions. The extract does not have a well-documented taste or odor threshold, but it is typically used to impart a natural, earthy character to formulations. Its sensory role is often as a modifier or a background realism enhancer in both flavor and fragrance applications.

3. Natural Occurrence & Formation
Lithospermum officinale is native to Europe and parts of Asia, where it grows in wild and cultivated forms. The extract is obtained from the roots of the plant, which are rich in naphthoquinones, particularly shikonin and its derivatives. These compounds are responsible for the characteristic color and some of the sensory properties of the extract. The formation of these compounds occurs naturally in the plant as part of its secondary metabolism. Lithospermum officinale extract is often used in products labeled as "natural" due to its plant-based origin.

4. Use in Flavors
In flavor applications, Lithospermum officinale extract is used primarily for its earthy and slightly sweet notes, which can enhance the complexity of herbal and root-based flavor profiles. It is typically used in low concentrations, often in the range of 1-10 ppm in finished products, depending on the desired intensity and the specific application. The extract is relatively stable under typical food processing conditions, but care should be taken to avoid excessive heat, which can degrade some of its volatile components.

5. Use in Fragrances
Lithospermum officinale extract is utilized in fragrance formulations for its earthy, grounding aroma. It is commonly found in fragrance families such as woody, oriental, and herbal. The extract serves as a modifier or a trace realism note, providing depth and complexity to the fragrance. Typical concentration ranges in fragrances are from 0.1% to 1%, depending on the desired effect and the product type. It contributes primarily to the base notes due to its low volatility.

5a. Key Constituents (Typical)
The key constituents of Lithospermum officinale extract include shikonin, acetylshikonin, and other naphthoquinone derivatives. These compounds are responsible for the extract's characteristic color and some of its sensory properties. The composition of the extract can vary based on factors such as the plant's growing conditions and the extraction method used.

6. Regulatory Status (Regional Overview)
In the United States, Lithospermum officinale extract is not specifically listed as GRAS by FEMA, but it may be used in flavors under general safety provisions. In the European Union, it is subject to the regulations under Reg. (EC) No 1334/2008, although it does not have a specific FL number. The regulatory status in the United Kingdom aligns with the EU post-Brexit. In Asia, particularly in Japan and China, the extract is used in traditional medicine, but specific flavor or fragrance regulations may vary. In Latin America, regulatory information is limited, and usage is typically guided by general safety assessments.

7. Toxicology, Safety & Exposure Considerations
For oral exposure, Lithospermum officinale extract is generally considered safe at low concentrations typical in flavor applications, although specific ADI or MSDI values are not well-documented. Dermal exposure in fragrance use is generally safe, but formulations should comply with IFRA guidelines to avoid irritation or sensitization. Inhalation exposure is minimal due to the extract's low volatility, but occupational exposure should be managed with standard safety practices. The risk profiles for food and fragrance applications are similar, with no significant differences noted.

8. Practical Insights for Formulators
Lithospermum officinale extract is valued for its ability to impart a natural, earthy character to both flavors and fragrances. It synergizes well with other herbal and woody notes, enhancing the overall complexity of the formulation. Formulators should be cautious of overuse, as its distinct aroma can dominate if not balanced properly. It is often under-utilized in modern formulations, providing an opportunity for innovation in natural product lines.

9. Confidence & Data Quality Notes
The data on Lithospermum officinale extract is well-established in terms of its sensory properties and typical uses. However, there are gaps in specific regulatory approvals and detailed toxicological data, which are often filled by industry-typical practices and safety assessments. Formulators should verify the latest regulatory updates and safety data when considering new applications.

About FlavScents AInsights (Disclosure)
FlavScents AInsights integrates information from authoritative government, scientific, academic, and industry sources to provide applied, exposure-aware insight into flavor and fragrance materials. Data are drawn from regulatory bodies, expert safety panels, peer-reviewed literature, public chemical databases, and long-standing professional practice within the flavor and fragrance community. Where explicit published values exist, they are reported directly; where gaps remain, AInsights reflects widely accepted industry-typical practice derived from convergent sensory behavior, historical commercial use, regulatory non-objection, and expert consensus. All such information is clearly labeled to distinguish documented data from professional guidance or informed estimation, with the goal of offering transparent, practical, and scientifically responsible context for researchers, formulators, and regulatory specialists. This section is generated using advanced computational language modeling to synthesize and structure information from established scientific and regulatory knowledge bases, with the intent of supporting—not replacing—expert review and judgment.
