TL;DR: Rhodojaponin III, grayanotoxin III, and kalmanol, three grayanoid diterpenes, were isolated and identified as the most active constituents in dried flowers of the Chinese insecticidal plant, Rhododendron molle.

TL;DR: T tobacco cells treated with cryptogein, an extracellular protein produced by Phytophthora cryptogea, accumulated ethylene and sesquiterpenoid compounds, mainly capsidiol, which makes tobacco resistant to the pathogen P. parasitica var.

TL;DR: Three new carbazole alkaloids, 3-formyl-6-methoxy-carbazole, methyl carbazoles-3-carboxylate and 3-1,6-dimethoxy carbazolines, were reported from the root of Clausena lansium as discussed by the authors.

TL;DR: In this paper, three new sesquiterpenes, (−)-guaia-1(10),11-dien-15-al, (−-selina-3,11-Dien-9-one, and (+)-selina -3, 11-Dian-9 -ol, have been isolated from Aquilaria agollocha (agarwood), based on detailed spectroscopic analyses and synthesis.

TL;DR: The mechanism of enzymic methylenedioxy bridge group formation from an o -methoxyphenol function is discussed and both enzymes were drastically induced 20 hr after challenging the cell suspension culture with elicitor.

TL;DR: In this article, a review of acetylenes and related compounds, such as thiophenes, alkamides, unsaturated alkyl ketones and hydrocarbons, which have been isolated from the tribe Heliantheae (Asteraceae) are listed.

TL;DR: Two new friedelane-type triterpenes, named as cangoronine and ilicifoline respectively, have been isolated from Maytenus Ilicifolia by spectroscopic and X-ray analyses and the cytotoxic activities of these compounds are reported.

TL;DR: It is suggested that fatty acid composition might be utilized for the classification of Spirulina strains.

TL;DR: 3,4-Dihydroxyphenylalanine 4,5-dioxygenase, a central enzyme in the biogenesis of betalains, has been purified from the mushroom Amanita muscaria and converted to α-hydroxymuconic e-semialdehyde derivatives.

TL;DR: One new and three known phenylpropanoids have been isolated from the leaves of Piper sarmentosum as mentioned in this paper, which are 1-allyl-2,6-dimethoxy-3,4-methylenedioxybenzene, 1-(1- E -propenyl)-2,4,5-trimethoxybenzenes, and 1 -allyl 2,2,methoxy 4,5 -methylenedioxene.
