Abstract
Introduction Drug-induced liver injury is the most common cause of acute liver failure. Off-Target effect "hepatotoxicity "frequently detected during clinical examination of patients on anti-Tb medication particularly isoniazid (INH), and rifampin (RMP). However, there is no any treatment option against isoniazid and rifampicin induced hepatotoxicity. It is, therefore, necessary to search for effective affordable and safe drugs from medicinal plants for the prevention of liver toxicity caused by isoniazid and rifampicin. The aim the current study is to evaluate hepatoprotective effect of hydro methanol extract from Otostegia integrifolia leaves in isoniazid and rifampicin-induced hepatotoxicity in Swiss albino mice. Methods O. integrifolia leaves powder was macerated in hydromethanol and thirty Swiss albino mice 29.0-40.6 g were grouped in to five groups. Group I were given 20 ml/kg distilled water, group II were given 100 mg INH and 150 mg RIF per kg body weight. Group III, group IV, and group V were given 200 mg extract, 400 mg extract, and 100 mg of N-acetyl cysteine respectively per kg 1hr before induction with 100 mg INH plus 150 mg RIF per kg. The treatments were followed for 14 days. On the 15th day, all mice were anaesthetized with diethyl ether; blood samples were collected for the assessment liver enzyme and function test. Results Group II mice's serum ALT, AST and total bilirubin levels were significantly increased and serum total protein and albumin levels were significantly decreased as compared with group I mice. The groups of mice treated with O. integrifolia at a dose of 400 mg/kg and N-acetyl cysteine AST, ALT and total bilirubin level were significantly decreased; and total protein and albumin levels were significantly (P < 0.05) increased as compared with group II. The liver index of the group IV showed decreased (P < 0.05) as compared to the group II. Conclusion Evidence from our study revealed that the hydromethanol extract of O. integrifolia has a hepatoprotective effect against isoniazid and rifampicin-induced hepatotoxicity in Swiss Albino mice. This protective effect of O. integrifolia extract may be based on its metal ion reducing power, free radical scavenging activity, and anti-inflammatory activity and could be used as a potential therapeutic option.

Abstract
Spiro-9,13-epoxy-labdane diterpenoids are commonly found in Leonurus species, particularly in Leonurus japonicus Houtt., which is a medicinal herb of long-standing use in Asia and in which such spiro-heterocycles are present in at least 38 diterpenoids. Here, through generation of a transcriptome and functional characterization of six diterpene synthases (diTPSs) from L. japonicus, including three class II diTPSs (LjTPS1, LjTPS3, and LjTPS4) and three class I diTPSs (LjTPS5, LjTPS6, and LjTPS7), formation of the spiro-9,13-epoxy-labdane backbone was elucidated, along with identification of the relevant diTPSs for production of other labdane-related diterpenes. Similar to what has been found with diTPSs from other plant species, while LjTPS3 specifically produces the carbon-9 (C9) hydroxylated bicycle peregrinol diphosphate (PPP), the subsequently acting LjTPS6 yields a mixture of four products, largely labda-13(16),14-dien-9-ol, but with substantial amounts of viteagnusin D and the C13-S/R epimers of 9,13-epoxy-labda-14-ene. Notably, structure-function analysis identified a critical residue in LjTPS6 (I420) in which single site mutations enable specific production of the 13S epimer. Indeed, extensive mutagenesis demonstrated that LjTPS6:I420G reacts with PPP to both specifically and efficiently produce 9,13S-epoxy-labda-14-ene, providing a specialized synthase for further investigation of derived diterpenoid biosynthesis. The results reported here provide a strong foundation for future studies of the intriguing spiro-9,13-epoxy-labdane diterpenoid metabolism found in L. japonicus.

Abstract
Within the Open Science project entitled 'Botanic Garden, factory of molecules', a multidisciplinary study approach was applied to Ballota acetabulosa (L.) Benth., at the Ghirardi Botanic Garden (Toscolano Maderno, BS, Italy). Micromorphological and histochemical investigations were performed on the secreting structures of the vegetative and reproductive organs under light, fuorescence and electronic microscopy. Concurrently the characterization of the volatiles spontaneously emitted from leaves and flowers were examined. Four trichome morphotypes were identified: peltate and short-stalked, medium-stalked and long-stalked capitate trichomes, each with a specific distribution pattern. The histochemical analysis was confirmed using ultrastructural observations, with the peltates and long-stalked capitates as the main sites responsible for terpene production. The head-space characterization revealed that sesquiterpene hydrocarbons dominated both in leaves and flowers, with γ-muurolene, β-caryophyllene and (E)-nerolidol as the most abundant compounds. Moreover, a comparison with literature data concerning the ecological roles of the main compounds suggested their dominant roles in defence, both at the leaf and flower level. Hence, we correlated the trichome morphotypes with the production of secondary metabolites in an attempt to link these data to their potential ecological roles. Finally, we made the obtained scientific knowledge available to visitors of the Botanic Garden through the realization of new labelling dedicated to B. acetabulosa that highlights the 'invisible', microscopic features of the plant.

Abstract
Phytochemical investigations of an extract of the aerial parts of Rydingia persica led to the isolation of 14 labdane-type diterpenoids, of which compounds 1-5, 8, and 12-14 turned out to be new natural products, while the remaining compounds were isolated for the first time from the genus Rydingia. Their structures were elucidated using 1D- and 2D-NMR and mass spectrometry, and their absolute configurations were determined by quantum chemical calculation methods. Furthermore, DP4+ NMR chemical shift probability calculations were performed for compounds 12-14, in order to elucidate the orientation of the ambiguous chiral center at C-15, prior to absolute configuration determination. The methanol extract of the aerial parts of R. persica along with subfractions obtained and selected isolated compounds were evaluated for their effects on inflammation-related factors such as nitrotyrosine formation, IL-6 release, and TNF-α release, along with tight-junction proteins claudin-1 and occludin expression in LPS-stimulated HaCaT cells. Occludin and claudin-1 are tight-junction proteins, which play a pivotal role in wound repair mechanisms. Overall, the subfractions and compounds isolated showed moderate to high activity, indicating that labdane-type diterpenoids contribute to the anti-inflammatory and wound-healing activity of R. persica.
