Salvia digitaloides
Salvia digitaloides · Accepted scientific name
Scientific literature: Very Sparse (0 studies) · ★☆☆☆☆
Salvia digitaloides is a unique botanical species that holds significant interest for pharmacological research. While the whole plants are often studied, much of the focus lies on the chemical properties found within the root. Scientists frequently utilize a 95% ethanol extract to isolate the bioactive compounds contained within its tissues. This specific preparation method allows for a concentrated analysis of the plant's potential medicinal properties. Understanding these extracts provides valuable insight into the complex biological profile of this Salvia species.

Biological Activities
Compounds
Conditions
Salvia digitaloides contains isoprenylated flavonoids, such as compound 2, that strongly and dose-dependently inhibit $\text{Ca}_{\text{v}}3.1$ low voltage-gated $\text{Ca}^{2+}$ channels. The plant also yields bioactive compounds like sadigitaloide A, which demonstrates noticeable anti-inflammatory activity against lipopolysaccharide (LPS)-induced TNF-$\alpha$ production in rat macrophage cells. Furthermore, sadigitaloide B provides significant neuroprotection for dopaminergic neurons in a Caenorhabditis elegans model injured by 6-OHDA. These specific diterpenoids and sesquiterpenoids highlight the plant's potential for treating inflammatory and neurological conditions. Collectively, these chemical constituents illustrate the diverse therapeutic mechanisms inherent to the species.
Preparations
Salvia digitaloides is prepared as a 95% ethanol extract to facilitate the isolation of various bioactive compounds. This extraction process utilizes the whole plants of the species to ensure a comprehensive range of diterpenoids and sesquiterpenoids are obtained. By using the whole plants, researchers were able to identify several undescribed chemical structures. The 95% ethanol extract serves as the primary medium for recovering these important medicinal components. Consequently, the preparation of Salvia digitaloides as a whole plant ethanol extract is essential for studying its anti-inflammatory and neuroprotective properties.
Parts used
Salvia digitaloides serves as a significant subject of pharmacological study due to its unique chemical profile. Recent research has successfully isolated several new isoprenylated flavonoids, specifically Saldigones A-C, from the roots of this plant. These diverse architectures, including flavanone and pterocarpan structures, were identified through extensive spectroscopic analysis. Most notably, these compounds demonstrate a capacity to interact with calcium channels within the body. One specific isolate was found to strongly and dose-dependently inhibit CaV3.1 low voltage-gated calcium currents.
