Terpenoids from the Stems of Drypetes congestiflora
Two new eremophilane-type sesquiterpenoids, 1α-hydroxyeremophila-6,9,11-trien-8-one (1), 4α-hydroxyeremophila-1,9-diene-3,8-dione (2), and a new friedelane-type triterpenoid, friedelane-3α,16β-diol
Total Syntheses and Biological Evaluation of (±)-Botryosphaeridione, (±)-Pleodendione, 4-epi-Periconianone B, and Analogues.
The total syntheses of (±)-botryosphaeridione, (±)-pleodendione, (±)-hoaensieremodione, 4-epi-periconianone B, and their analogues have been accomplished for the first time. All the synthesized
Uvarmicranones A and B, two new benzoquinones and cytotoxic constituents from the stems of Uvaria micrantha (A. DC.) Hook. f. & Thomson
Abstract Two novel benzoquinones, uvarmicranones A (1) and B (2), along with 15 known compounds (3 − 17) were isolated from the stems of Uvaria micrantha (Annonaceae). Their structures were
Sesquiterpenoids from the heartwood of Juniperu s chinensis
A new sesquiterpenoid, 11-hydroxy-valenc-1(10),3(4)-dien-2-one (3), two chemically synthesized but first isolate from nature, 3-oxocedran-8β-ol (1) and valenc-1(10),3(4),11(12)-trien-2-one (2) along

A high-quality chromosome-scale assembly of S. glabra genome is presented by combining Illumina HiSeq, Pacific Biosciences sequencing, and Hi-C technologies, which is the first sequenced genome of the subfamily Caesalpinioideae.
Triphenylphosphonium Cations of the Diterpenoid Isosteviol: Synthesis and Antimitotic Activity in a Sea Urchin Embryo Model.
The results obtained using the sea urchin embryo model suggested that TPP conjugates of isosteviol induced mitotic spindle defects and mitotic arrest presumably by affecting mitochondrial DNA.


Triterpenoids with antimicrobial activity from Drypetes inaequalis.
The air-dried stems and ripe fruit of Drypetes inaequalis Hutch were studied and triterpenes were tested for antimicrobial activity against some Gram-positive and Gram-negative bacteria, and two appeared to be modestly active.
Phenolic Constituents of Selaginella doederleinii.
Lignans are described here for the first time in the family Selaginellaceae for their cytotoxic activity against L 929 murine cells accounts for the use of the plant in traditional Chinese medicine as an anticancer agent.
Lignans and neolignans from Stelleropsis antoninae
The results of this study show that siringaresinol, a well-known bioavtive compound, and its glucosides are the main lignans, and lariciresinol and coniferyl alcohol derivatives are themain neolignans of S. antoninae.
Cytotoxic phenylpropanoid glycosides from the stems of Smilax china.
Bioassay-guided fractionation of an ethanol extract of Smilax china led to the isolation of nine phenylpropanoids including six new compounds, smilasides A-F (1-6), and three known phenylpropanoids,
Sesquiterpene lactone and friedelane derivative from drypetes molunduana.
Phytochemistry and antifungal properties of the newly discovered tree Pleodendron costaricense.
Antifungal assays with the two major compounds, 1 and 2, were carried out, and results showed a high activity of 1 against Alternaria alternata, Candida albicans azole-resistant strain D10, and Wangiella dermatitides and a combination of the dialdehyde sesquiterpenes with dillapiol showed a synergistic antifungAL effect with 1 and an additive effect with 4 and 5.
Lignan glycosides from bark of Albizzia myriophylla.
Three new lignan glycosides have been isolated from the bark of Albizzia myriophylla by isolating 6-epi-syringaresinol 4-O-β-d-apiofuranosyl-(1→2)-β- d-glucopyranoside and three closely related newLignan Glycosides.
