摘要:基于高效液相色谱与电喷雾正离子化多级离子阱质谱联用,通过 HPLC-Esims(N) 方法获得了木皮地下部分和叶子的比较代谢物分析.仔细研究每个色谱峰的 HPLC-Esims(N) 碎裂模式,特别是诊断性子离子的鉴定,使我们能够快速筛选属于不同类别的皂苷,例如脱水/或非呋甾烷醇,螺甾烷醇和孕烷苷,并及时突出两个植物部分之间的异同.这种方法,然后通过 1D 和 2D NMR 实验进行分离和结构解析,导致从地下部分鉴定了 11 种皂苷,其中两种脱水呋喃甾醇苷和一种新的vespertilin衍生物,以及来自r. Ponticus叶子的九种皂苷,以前从未报道过.所取得的结果突出了在 R. Ponticus 叶子中而不是在植物的地下部分中呋甾醇糖苷衍生物的普遍存在,这显示出更广泛的结构多样性.特别是,首次从 Ruscus 物种中分离出脱水呋喃烷醇衍生物是一个不寻常的发现,这使得 R. Ponticus

权利人:LVMH RECH
摘要:The present invention relates to a method of cosmetic treatment for combating the effects of skin ageing and to novel cosmetic compositions which are particularly suitable for carrying it out. According to the invention, at least one agent for promoting the adhesion of the keratinocytes of the epidermal basal layer to the dermo-epidermal junction, especially to the collagen IV of said junction, such as, in particular, a divalent metal salt or complex, preferably magnesium aspartate or magnesium chloride, is used, optionally in association with a stimulant of collagen IV synthesis and/or a stimulant of collagen VII synthesis.

标 题:Topical Nutraceutical Compositions with Selective Body Slimming and Tone Firming Antiaging Benefits
发明人：GUPTA SHYAM K
摘要:I have discovered cosmetic or topical pharmaceutical compositions for external body part or organ slimming, firming, cellulite reduction, fat-reduction, and obesity control benefits that are in synergistic combination with benefits for the treatment of skin aging, skin wrinkles reduction, skin exfoliating, treatment of acne, treatment of rosacea, age-spots reduction, skin surface whitening, skin surface brightening striae distensae (stretch marks) reduction, treatment of pimples, treatment of skin infections and lesions, spider veins reduction, blood microcirculation (venous insufficiency) improvement, UVA/UVB protection of skin, and skin redness reduction. These compositions thus provide multiple combinations of skin and external body part or organ enhancement benefits that can be selective and specific for external body parts and organs such as face, chin, cheeks, arms, “love handlesâ€? in abdomen area, eye lids and eye zone, neck, breasts, thighs, and hips. These compositions include a body beneficial composition selected from certain nutraceutical, cosmetic, and pharmaceutical ingredients, a composition to promote collagen and elastin synthesis in the skin, and a cosmetically or pharmaceutically acceptable delivery ystem.

摘要:This invention relates to Schiff's bases derived from amino acids and hydroxyaryl alkyl ketones, or a plant extract containing the same, having general chemical structure in FIG. 1 for topical application. This invention also relates to certain metal complex of said Schiff's bases, which have a crown-like appearance in their three-dimensional chemical structure, as in FIG. 2 . The Schiff's bases and their metal complexes of the present invention are useful for the modulation of metal-activated enzymes and metalloenzymes, such as Phenylalanine Hydroxylase, Tyrosine Transaminase, Phenylalanine Transaminase, Tyrosinase, various MMP (Matrix metalloproteases), Superoxide dismutase, 5-Alpha Reductase, and citrate lyase. These are further suitable for multifunctional topical methods for skin whitening, skin wrinkles reduction, skin antiaging, collagen synthesis, acne control, hair loss prevention, hair graying control, and facial oil control.
