Silktree Albizzia Extract: Taxonomic Integrity & Active Markers
A rigorous analytical breakdown of *Albizia julibrissin* Durazz. (Fabaceae), elucidating the differentiation between Cortex Albizziae (He Huan Pi) and Flos Albizziae (He Huan Hua), standardized saponins, and neurological bio-targets.
Triterpenoid Saponins (Julibrosides)
The primary pharmacological drivers in Cortex Albizziae are complex oleanane-type triterpenoid saponins known as Julibrosides (A1, A2, A3, B1, C1). Our standardized wholesale batches undergo validated HPLC-ELSD and UHPLC-MS/MS fingerprinting to guarantee consistent therapeutic fractioning without synthetic adulteration.
- Assay standard: 5% to 20% Total Triterpenoid Saponins
- Key Reference: Julibroside J1, Albizziasaponins A-E
- Receptor Affinity: 5-HT1A and GABA-A allosteric modulation
Flavonoid & Lignan Complexes
Derived primarily from Flos Albizziae (Silk Tree Flower), our polyphenol-rich fractions isolate high-affinity quercitrin, isoquercitrin, hyperoside, and lignans. These components deliver potent neuro-protective activity, counteracting oxidative stress-induced neuroinflammation across the blood-brain barrier.
- Standardized UV/HPLC Flavonoids: ≥ 10.0% to 30.0%
- Free Radical Quenching: DPPH IC50 < 28.5 μg/mL
- Antioxidant Synergy: Inhibits lipid peroxidation in microglial cells
Neuro-Modulation & Cortisol Regulation
Clinical interest in Silktree Albizzia Extract centers on its dual action on the hypothalamic-pituitary-adrenal (HPA) axis and monoaminergic neurotransmission. Peer-reviewed pharmacological models demonstrate significant anxiolytic and sleep-normalizing behaviors without the sedative side-effects associated with benzodiazepines.
- Cortisol attenuation under acute psychological stress models
- Upregulation of Brain-Derived Neurotrophic Factor (BDNF)
- No motor-coordination suppression or daytime somnolence
Scientific Formulation Note: Cortex Albizziae vs. Flos Albizziae Selection
Formulators must distinguish between the stem bark (*Cortex Albizziae*) and flower (*Flos Albizziae*). Cortex Albizziae possesses higher densities of cytotoxic and neuroactive triterpenoid saponins suited for deep nervous system calming and mood stabilizing nutraceuticals. Flos Albizziae is richer in aromatic volatiles, flavonols, and antioxidant glucosides, making it the preferred candidate for daytime calm, functional beverage infusions, and premium neuro-cosmetics. ShineHerb provides both standardized isolates and bespoke customized dual-ratios.

Frequently Asked Questions by Industrial Sourcing Teams
Comprehensive technical and commercial clarity regarding botanical authenticity, testing standards, lead times, and customized OEM specifications.
Cortex Albizziae (*He Huan Pi*) is the dried stem bark of *Albizia julibrissin*, valued primarily for its high concentration of triterpenoid saponins (Julibrosides) and indicated for deep emotional balance, anxiolytic support, and sleep restoration formulas. Flos Albizziae (*He Huan Hua*) consists of the inflorescences/flowers, rich in flavonoids (quercitrin, isoquercitrin) and volatile oils, optimal for daytime stress mitigation, antioxidant formulas, clear beverages, and topical cosmeceuticals.
Because saponins lack strong UV chromophores, our internal QC and certified third-party labs utilize High-Performance Liquid Chromatography coupled with Evaporative Light Scattering Detection (HPLC-ELSD) or UHPLC-MS for quantitative Julibroside identification. Flavonoid fractions from Flos Albizziae are quantitated using UV-Vis spectrophotometry against a calibrated quercitrin standard curve or reversed-phase HPLC-DAD.
Our standard minimum order quantity (MOQ) for catalog specifications (e.g., 10:1, 20:1, or 10% standardized saponins) is 25 kg (one standard fiber drum).
