Hexane extract from roots: wound healing properties and membrane-disruptive activities against methicillin-resistant .

Introduction: The extensively used Hemsl. (Lauraceae) in traditional Chinese medicine has been specifically employed for wound healing and treating skin diseases in cattle and horses, suggesting its potential antibacterial properties. To explore the antibacterial activities of plants, we investigated the chemicals, antibacterial activities and wound healing and of the n-hexane fraction of roots (LCH).

Traditional Knowledge and Efficacy Analysis of an Emerging Medicinal Food Plant: .

(Hua) Engl. ex K. Krause, locally known as (bitter greens) or , is a widely consumed wild vegetable and traditional herbal medicine in western Yunnan.

 (Ranunculaceae), a new species from West Yunnan, China.

Based on morphological and plastid data, we have described and confirmed that distributed in Tongbiguan Provincial Nature Reserve, Yingjiang County, Yunnan Province, is a new species of . It is distinctly different from C.teetasubsp.

Traditional uses, phytochemistry, pharmacology, toxicity and clinical application of traditional Chinese medicine : a review.

Cynoglossum amabile, a member of the Boraginaceae family, is a well-known traditional Chinese medicine and ethnomedicine known as Daotihu. Despite several studies confirming the presence of bioactive pyrrolizidine alkaloids such as amabiline, ambelline, echinatine, europine, and others in , there has been no comprehensive review of its traditional uses, phytochemistry, and pharmacology thus far. This review was conducted by thoroughly examining the literature and analyzing network databases.

A Middle Eocene lowland humid subtropical "Shangri-La" ecosystem in central Tibet.

Tibet's ancient topography and its role in climatic and biotic evolution remain speculative due to a paucity of quantitative surface-height measurements through time and space, and sparse fossil records. However, newly discovered fossils from a present elevation of ∼4,850 m in central Tibet improve substantially our knowledge of the ancient Tibetan environment. The 70 plant fossil taxa so far recovered include the first occurrences of several modern Asian lineages and represent a Middle Eocene (∼47 Mya) humid subtropical ecosystem.

A new furostanol saponin from Asparagus cochinchinensis.

A new furostanol saponin, (25S)-26-O-β-D-glucopyranosyl-5β-furost-20(22)-en-3β, 15β,26-triol-3-O-[α-L-rhamnopyranosyl-(1-4)]-β-D: -glucopyranoside, namely, aspacochioside D (1) were isolated from Asparagus cochinchinensis (Lour.) Merr, along with three known saponins, aspacochioside C (2), (25S)-5β-spirostan-3β-yl-O-[O-α-L-rhamnopyranosyl-(1-4)]-β-D-glucopyranoside (3), and pseudoprotoneodioscin (4). The structure of 1 was elucidated on the basis of chemical reactions and spectral analysis (IR, GC, ESI-MS, (1)H-NMR, (13)C-NMR, DEPT, HMBC, HMQC and NOESY).

Lignans from Trachelospermum jasminoides.

Seven lignans having a diarylhydroxybutyrolactone skeleton were isolated from the leaves and stems of Trachelospermum jasminoides (Lindl.) Lem. Their structures were elucidated to be nortrachelogenin 8' -O-beta-D-glucopyranoside (1), nortrachelogenin 5'- C- beta-D-glucopyranoside (2), trachelogenin amide (3), nortracheloside, trachelogenin, tracheloside, and trachelogenin 4'- O- beta-gentiobioside, respectively, on the basis of spectroscopic analyses.

[Studies on chemical constituents of Ervatamia hainanensis].

Objective: To study the chemical constituents of Ervatamia hainanensis.

Method: The compounds were separated and purified by column chromatography with silica gel, and identified by IR, MS, NMR and 2D-NMR.

Result: Five compounds were identified as I (isolariciresinol 9-O-beta-D-glucopyranoside), II (cycloartenol), III (beta-amyrin acetate), IV (beta-sitosterol), V (daucosterol), respectively.
