    Cycloastragenol: The Telomerase-Activating Marvel from Astragalus membranaceus

    For over 2,000 years, Astragalus membranaceus (Huangqi) has been revered in Traditional Chinese Medicine as the "Supreme Qi-Tonifying Herb." Modern science now validates its legendary status through cycloastragenol (CAG)—a bioactive tetracyclic triterpenoid that exemplifies nature’s power to combat aging, immune dysfunction, and chronic disease. As a premier manufacturer of plant extracts, we unlock this potent compound using cutting-edge purification technologies to deliver >98% purity for global health innovations. Botanical Origin and Chemical Profile Cycloastragenol is the aglycone of astragaloside IV, isolated from the roots of Astragalus membranaceus (Fisch.) Bge. var. mongholicus. This small molecule (C??H??O?, MW: 490.72) features a unique 9,19-cyclolanostane structure with four hydroxyl groups critical to its bioactivity. Our extraction process preserves its integrity through: Ethanol/water gradient extraction followed by chromatographic purification Strict QC protocols: HPLC-DAD/ELSD validation, NMR and mass spectrometry confirmation7 Stability optimization: -20°C storage in amber vials to prevent degradation Table 1: Key Specifications of Our Cycloastragenol Parameter Specification CAS No. 78574-94-4 / 84605-18-5 Purity ≥98% (HPLC) Appearance White to off-white crystalline powder Storage -20°C, desiccated Biological Activity Telomerase activation, CTSB inhibition Dual Mechanisms of Action: From Telomeres to Tumor Immunity 1. Telomerase Activation & Anti-Aging Effects Cycloastragenol is nature’s first documented telomerase activator. By binding the catalytic site of telomerase reverse transcriptase (TERT), it: Extends telomeres in CD4+/CD8+ T-cells, delaying replicative senescence Upregulates tert and bcl2 mRNA in neuronal cells, protecting against oxidative stress Enhances antiviral immunity by 300% in human T-lymphocytes (in vitro) This mechanism underpins its potential in age-related disorders—from skin rejuvenation to neuroprotection. 2. Immuno-Oncology: Unblocking MHC-I Antigen Presentation Groundbreaking 2022 research revealed cycloastragenol’s cancer-fighting secret: it directly targets cathepsin B (CTSB) at residues A77/G198. This interaction: Blocks MHC-I degradation in lysosomes, increasing tumor antigen presentation Elevates immunogenic genes (*H2-k1*, B2m, CD74) by 3–5-fold per scRNA-seq data Synergizes with anti-PD-1 therapy, shrinking colon tumors by 60% vs. monotherapy in murine models "CAG reshapes the tumor microenvironment—it’s a ‘checkpoint inhibitor enhancer’ for cold tumors." — Journal for Immunotherapy of Cancer, 2022 Applications in Modern Therapeutics Validated in peer-reviewed studies, cycloastragenol holds promise for: Age-delay supplements: Doubles telomerase activity at 1 μM (6-day exposure Oncology adjuvants: 10 mg/kg/day dosing with PD-1 antibodies boosts CD8+ T-cell infiltratio Neuroprotective agents: Induces CREB phosphorylation to alleviate depression-like behaviors Anti-inflammatory formulations: Suppresses NLRP3 inflammasomes in psoriasis models Quality Commitment We ensure pharmaceutical-grade cycloastragenol through: Bioactivity assays: Telomerase activation (TRAP assay), CTSB binding (MST validation) Traceability: Sustainable sourcing from GAP-certified Astragalus farms Scalability: 50–1000 kg batches with COA, stability data, and customs documentation The Future Is Natural Cycloastragenol bridges ancient wisdom and 21st-century science.

  • Bakuchiol: Nature’s Answer for Advanced Skincare and Health Innovation
    05 Jun
    Bakuchiol: Nature’s Answer for Advanced Skincare and Health Innovation

    For centuries, Psoralea corylifolia (commonly known as Bakuchi) has been revered in Ayurveda and Traditional Chinese Medicine. Today, its potent bioactive compound—Bakuchiol (C??H??O)—stands at the forefront of cutting-edge cosmetic and nutraceutical research. Extracted from the seeds of this resilient legume, Bakuchiol combines ancient wisdom with validated scientific benefits to deliver multifunctional solutions for modern health and beauty challenges. Unlocking Bakuchiol’s Science-Backed Mechanisms 1. Longevity & Cellular Resilience via DAF-16/FOXO PathwayGroundbreaking research reveals Bakuchiol’s profound anti-aging properties. In C. elegans (a model organism for aging studies), Bakuchiol at 37.5 μM extends lifespan by 38% by activating the evolutionarily conserved IIS/DAF-16 pathway. This triggers: Nuclear translocation of DAF-16 (homologous to human FOXO1), enhancing stress-response gene expression. Upregulation of SOD-3 (superoxide dismutase), boosting antioxidant capacity by 2.3× and combating oxidative damage . Dose-dependent protection against heat and ROS-induced stress, independent of gut microbiota. 2. Multi-Targeted Bioactivity for Holistic ApplicationsBakuchiol’s small molecular structure enables versatile interactions with biological targets: Skin Regeneration: Stimulates collagen synthesis, inhibits matrix metalloproteinases (reducing wrinkles), and suppresses tyrosinase (brightening skin). Antimicrobial Action: Disrupts membranes of S. aureus, E. coli, and C. albicans. Anti-Inflammatory & Estrogenic Effects: Modulates TNF-α/IL-1β and shows potential for bone health . Why Purity ≥99% Is Non-Negotiable Raw Psoralea corylifolia extract contains phototoxic furanocoumarins (e.g., psoralen, isopsoralen), which pose significant safety risks. Our advanced purification process ensures: Ultra-Pure Bakuchiol (≥99%): Using low-pressure supercritical CO? extraction followed by ethanol solvent separation, alkali treatment, and dynamic resin chromatography to eliminate allergens and toxins. Zero Residual Solvents: Unlike petroleum ether/acetate methods, our green technology avoids toxic contaminants. Stability & Scalability: Optimized for industrial production without compromising efficacy. Bakuchiol in Modern Applications Sector Benefits Formulations Cosmetics Retinol-alternative (anti-aging, acne control); non-irritating, photo-stable, suitable for sensitive skin Serums, creams, sunscreens Nutraceuticals Antioxidant/anti-inflammatory support; bone health enhancement Capsules, functional foods Clinical Antimicrobial wound care; depigmentation therapy Gels, ointments Commitment to Sustainability & Efficacy Ethical Sourcing: Psoralea corylifolia is not endangered (IUCN status: Least Concern) and is cultivated under strict ecological guidelines. Clinical Validation: Bakuchiol matches retinol’s efficacy in improving skin elasticity and hyperpigmentation, with 44% less irritation in clinical trials. Global Compliance: EU/Korea/Japan-approved cosmetic ingredient; meets ISO 16128 standards for natural origin. Elevate your formulations with Bakuchiol—where nature’s resilience meets precision science.
