Lilium Candidum Bulb Extract is the active substance extracted from the dried fleshy Chemicalbook scale leaves of LiliumlancifoliumThunb. It mainly contains steroidal saponins, lily polysaccharides and other components, which have the characteristics of hypoglycemia, antioxidant, anti-tumor, anti-fatigue, enhance the immunity of the body, and improve the conversion rate of lymphocytes; not only has a wide range of clinical applications, but also has great development prospects as raw materials for processing health products.

The lily extract developed by KINTAI is mainly used in cosmetics, and phenols, polysaccharides and saponins are the main functional components of lily in cosmetics. As a raw material, lily can be widely used in various cosmetic products, and its functions are rich and diverse, including whitening, moisturizing, sun protection, acne removal, etc.

At present, phospholipids, phenolic acid glycerides, steroidal glycosides, steroidal alkaloids, proteins, amino acids and many other components have been extracted and isolated from lily. The hot methanol extract of lily of the lake (Liliumhenryi) bulbs has been chromatographically isolated 12 compounds, such as 1,2-O-diferuloylpropanetriol, 1-O-feruloy-2-O-P coumaryl propanetriol mixed with 1-O-P-coumaryl-2-O-feruloy, 1,3-O-diferuloylpropanetriol, 1-O-feruloy-3-O-P-feruloy propanol, 3,6'-O-diferuloylsuccinose, 4-O-acetyl-3,6'-diferuloylsuccinose, 4'-O-2-acyl-3,6'-O-diferuloylsuccinose, 3-O-feruloylsuccinose 6' -O(4-O-β-D-glucopyranoyl feruloyl) sucrose, (2s)-l-O-P-methoxycinnamoyl-3-O-β-D-glucopyranoside, (2s)-l-O-caffeoyl-3-O-β-D-glucopyranoside, and (25R)-3β,26-dihydroxy-5α-cholan-6,22-dione 3-O-β-D-glucopyranoside .

HPLC/ESIMS screening of steroidal saponins in lily Chromatographic conditions Column: Waters C18 column (150mm×3.9mm, 5μm); mobile phase: A(CH3CN)-B(H2O), B-phase concentration gradient: start, 85%; 40min, 15%; stop. flow rate: 0.5ml/min.
The post-column effluent of the HPLC was introduced into the electrospray ion source at a rate of 5 μl/min through a stainless steel manifold head, and the mass spectrometer was sampled in the positive ion state, and the mass spectrometry conditions were optimized based on the stability of the collected [M+H]+ signal intensity.

Preparation of the test samples
(1) A few steroidal saponins were prepared using a semi-preparative HPLC column: Waters C18 semi-preparative column (150 mm×3.9 mm, 5 μm); mobile phase: methanol-water-formic acid (55:45:0.15) Chemicalbook; flow rate: 1.5 ml/min. When the effluent from the HPLC column was concentrated under vacuum to 1/5 of its original volume, the The pH was adjusted to 2.5 with 1.0 mol/L formic acid and refluxed for 12 h. The pH was adjusted to neutral with 0.5 mol/L sodium hydroxide and extracted with an equal volume of ether three times and the ether was combined. The steroidal saponin element was obtained by blowing dry under nitrogen. The aqueous phase was used for the determination of sugar chain composition.
 

(2) A series of processes such as extraction with ethanol, liquid-liquid extraction with petroleum ether, trichloromethane and n-butanol and separation by column chromatography. The n-butanol extraction solution was concentrated under vacuum to a non-alcoholic taste, with an appropriate amount of water and adjusted to pH 8 with 0.5 mol/L sodium hydroxide, by AB-8 macroporous sorbent resin, first washed with water to remove the sugar and some pigments, and then desorbed steroidal saponins with ethanol. The post-column saponin effluent was concentrated under reduced pressure and the saponin extract was obtained by stepwise precipitation using ether-acetone (1:1) as precipitant.

Lily extract has the effect of proliferating fibroblasts and promoting the activity of tissue haploenzyme, which can enhance the metabolism of skin cells, has anti-aging function, and can promote the activity of luciferase, indicating that it has anti-inflammatory effect.
1. Moisturize the skin for a long time, supplement nutrition and regulate moisture.
2. Reduce skin sensitivity, improve blood circulation, and enhance skin metabolism.
3. Inhibit the activity of tyrosinase and the formation of melanocytes, effectively control the recurrence of pigmentation
