The Ames-induced mutagenic test result was 0.0, indicating a low genotoxicity risk and a solid safety foundation.
Plant Origins and Extraction Methods
Pedillaryis kneri Dalla Torre mainly comes from Pedillaryis kneri Dalla Torre, a plant belonging to the Scrophulariaceae family, widely distributed in specific geographic areas. Traditionally, Dalatorema Wormwood has been used in folk herbal medicine to treat various inflammatory diseases. Both its roots, stems, and leaves contain abundant active components, with jade leaf chrysosinic acid being one of the key components and possessing high extraction value.
The extraction method typically uses solvent extraction combined with chromatography separation technology. Common solvents include mixed solutions of methanol, ethanol, and water to ensure complete extraction of polar components. The typical extraction process is: after drying and crushing plant materials, ultrasound-assisted extraction or reflux extraction is used, followed by liquid-liquid separation to remove nonpolar impurities, and finally purification using high-performance liquid chromatography (HPLC). After purification, the structure of the jade leaf chrysanthemum is confirmed by mass spectrometry (MS), nuclear magnetic resonance (NMR), and other methods to ensure the purity of the extract and the accurate identification of active ingredients.
Pharmacological activity research
Research on the pharmacological activity of Jade leaf chrysolate mainly focuses on anti-inflammatory and anti-glycation aspects. Although its anti-glycation activity is relatively weak, it shows certain potential in regulating inflammation.
Anti-inflammatory activity
Inflammation is the common pathological basis of many diseases, and key molecular targets regulating inflammatory responses include IL-6, TNF, STAT3, NFKB1, and others. In vitro cell models, jade leaf chrysotide has shown regulatory effects on the above inflammatory factors, downregulating the expression of pro-inflammatory cytokines and suppressing the activation of inflammatory signaling pathways. For example, jade leaf chrysolate can inhibit the release of IL-6 and TNF-α, block phosphorylation of the STAT3 signaling pathway, and weaken the nuclear translocation of NFKB1, thereby reducing the intensity of inflammatory responses. Additionally, the inhibitory effect of jade leaf chrysosin on inflammation-related enzymes such as PTGS1 and PTGS2 (cyclooxygenases 1 and 2) has been reported, suggesting its potential application value in the mechanisms of nonsteroidal anti-inflammatory drugs (NSAIDs).
Anti-glycation activity
Glycation is the process by which proteins react non-enzymatically with carbohydrates to produce advanced glycation end products (AGEs), which are closely related to diabetes and its complications. Jade leaf chrynocylin exhibits weak anti-glycation activity and may have a protective effect by scavenging reactive oxygen species free radicals or inhibiting glycation intermediate formation, thereby slowing the accumulation of AGEs.
Other potential activities
Some studies also indicate that jade leaf chryotide regulates TRPV1 and TRPA1 ion channels, both of which play important roles in pain and inflammation responses. By modulating these targets, jade leaf chrysolate may play an auxiliary role in analgesic and neuroinflammation treatment. In addition, the regulation of NOS2 (induced nitric oxide synthase) expression also provides new perspectives on its anti-inflammatory mechanism.
Mechanism of action and molecular targets
The biological activity of jade leaf chrysonicotide is mainly realized through multi-target and multi-pathway synergistic interactions. Its anti-inflammatory mechanism involves several key molecular targets:
- IL-6 and TNF-α: As pro-inflammatory cytokines, upregulation of IL-6 and TNF-α expression is a hallmark of inflammatory responses. Jade leaf chrysosin reduces inflammatory responses by inhibiting the production of these factors.
- STAT3: As a signal transduction and transcription activator, STAT3 plays a central role in inflammation and immune regulation. Jade leaf chrysolate inhibits STAT3 phosphorylation, blocking its nuclear transcriptional activity.
- NFKB1: The NFKB signaling pathway is a key regulatory pathway in inflammatory responses. Jade leaf chrysotide reduces the expression of pro-inflammatory genes by inhibiting NFKB1 activation.
- CASP1 (caspase 1): involved in inflammatory cell death and activation of inflammasomes; the regulation of CASP1 by chrysosin-yl may affect the inflammatory cascade.
- TRPV1 and TRPA1: These two transient receptor potential channels play important roles in inflammation and pain transmission, and the regulatory effect of chrysosinic acid provides a molecular basis for its analgesic potential.
- PTGS1 and PTGS2: As key enzymes in prostaglandin synthesis, inhibition of PTGS1 and PTGS2 helps reduce inflammation and pain.
- NOS2: Induced nitric oxide synthase produces large amounts of NO during inflammation. Jade leaf chrynocylin affects the inflammatory microenvironment by regulating NOS2 expression.
Overall, jade leaf chrysonicotine synergistically regulates inflammation-related signaling pathways through multiple targets, exerting its anti-inflammatory effects and providing a theoretical basis for the development of novel anti-inflammatory drugs.
Druggability evaluation and pharmacokinetics
Druggability evaluation is a crucial step in the development of natural product drugs. The physicochemical properties of jade leaf chrysolate indicate good water solubility, but its strong hydrophilicity and large polar surface area may limit its oral bioavailability. Low blood-brain barrier permeability suggests limited application in the central nervous system, but it also reduces the risk of CNS toxicity.
The hERG channel inhibition test was negative, indicating a low risk of cardiotoxicity and good safety. The Ames test is non-mutagenic, further supporting its safety. Although systematic pharmacokinetic (PK) data are currently lacking, based on its structural characteristics, it is speculated that its metabolism in vivo may mainly occur through hepatic enzyme systems, with renal excretion predominant.
Future research should focus on its absorption, distribution, metabolism, and excretion (ADME) characteristics, optimize delivery routes and formulations, improve bioavailability, and evaluate its in vivo pharmacodynamic (PD) performance.
Prospects and outlooks for clinical applications
As a natural product, jade leaf chrysolate has multi-target anti-inflammatory activity and good safety, showing certain potential for clinical development. Its anti-inflammatory effects are suitable for various chronic inflammatory diseases, such as rheumatoid arthritis, inflammatory bowel disease, and certain neuroinflammatory conditions. Moreover, modulation of TRPV1 and TRPA1 channels offers potential applications in pain management.
However, current research mostly focuses on in vitro and animal models, lacking systematic preclinical and clinical research data. In the future, in-depth pharmacological and toxicological research is needed to clarify its mechanisms of action and therapeutic window, optimize formulation design, and conduct clinical trials to verify efficacy and safety.
In addition, although the antiglycation activity of jade leaf chrysonicotide is weak, combined with the synergistic effects of other natural products, it holds promise for the development of compound formulations for adjunctive treatment of diabetes and its complications.
Conclusion

Its unique chemical structure and physicochemical properties provide the basis for its pharmacological effects. Although its anti-glycation activity is relatively weak, it holds potential application value in inflammation regulation and pain management. In the future, pharmacokinetic research and preclinical evaluation should be strengthened to promote its translation into clinical application. Overall, as a candidate molecule for natural product drug development, the jade leaf chrysolate has broad prospects and application potential.
